Known issues

Item ID Problem Description Product Filter Workaround Release where fixed
x0002 Expanding the NAS pool with LUNs of sector size greater than 512 (e.g. 4KB) fails and stucks the system. FS76x0 Starting from version 9.03 the EqualLogic firmware prevents using such LUNs to expand the NAS pool, and is therefore strongly recommended. If already there, FluidFS Support should be contacted.
45777 Performance might be affected if AD is used as LDAP server and many (thousands) of groups have no gidNumber (i.e. Windows-only groups).
45745 When client belongs to multiple netgroups, NFS export access is evaluated alphabetically, by netgroup name, and may lead to unexpected behavior.
45740 FluidFS systems accessed via Layer-3 (IP-based, as oppose to standard, MAC-based) switches are likely to provide disruptive service. Assuming it is accessed via a standard Layer-2 (MAC based) switch, FluidFS can consistently assign and service different clients specifying same FluidFS VIP, with different FluidFS ports (MAC addresses). Layer-3 switches disrupt this scheme, by dynamically and continuously imposing a 1:1 mapping between an IP address (e.g. VIP) and a single MAC address. Specifically, an IP packet sent by a FluidFS system will cause the Layer-3 switch to direct ALL traffic to this IP (VIP) to the source switch port. If Layer-3 switch cannot be avoided, a partial workaround may be applied: using FluidFS GUI/CLI, manually map all {client-IP, VIP} pairs to FluidFS ports, where all pairs specifying same VIP are mapped to the same port. The drawbacks: 1. It will not survive a failover scenario, where FluidFS will not maintain the mapping between VIPs and FluidFS ports. 2. It is not practical for environments with many local clients. (Remote clients can be handled by mapping the router-IP as client-IP).
45655 Malformed IP addresses (e.g. "1.2.3") are not detected when configuring NTP servers in CLI
45654 Failover times for NFS sessions are sometimes longer than usual
45244 Upgrade to version 5.0.400014 fails when started immediately after service pack was uploaded. issue can be avoided by waiting few minutes after upload (to allow the service pack be extracted)
44563 During replication process, false error status "Secondary volume reclaim" is displayed This error can be ignored safely
43547 Files locked by an NFS client that locks a large amount of files (tens of thousands), may not be accessible from other clients after controller failover After failover, the lock list needs to be processed by the alternate controller which may take some time
43545 Accessing an NFS export may be very slow after controller failover/failback if a huge number (thousands) of files were locked on the related volume
43327 NDMP snapshots may not be deleted automatically
42798 Browsing the directory of NDMP backup may fail
42461 FluidFS will not accept file and share names with UTF8 characters in the range of 1F300 till 1F5FF
41323 Systems configured with external auditing may show Intermittent error: *File Auditing services are unavailable on all NAS Controllers* This message is triggered also when no real problem exists.
40792 Frequent "power down" activity may prevent the cluster from starting up
40587 Listing quota usage for many users (over 10,000) times out. This usually happens when latency to AD or LDAP server is too high.
40345 Recurring FSLowOnCache Events may appear when using the VDI module of VMWare Horizon.
40307 Replica Promotion may sometimes fail after 10 minutes, with "Error: System is busy please try again later." Despite the error the promotion continues and will complete later on
39898 Replication may fail when DR site has high load. Disable/Enable replication to revive it.
39424 FLuidFS may experience service interruptions when bound to AD on SAMBA server using NTLM Use Kerberos authentication
37254 Concurrent replications to same target may cause subsequent replicaton to hang after first replication finished.
37215 REST API operations may fail if arguments contain "/" (e.g path). Upgrade to Dell Storage Manager (DSM) 2016 R1 or later
37015 Operations involving share name may fail if share name is entered in a different case - althiugh share name should be case-insensitive Type in the share name exactly in the same case it was created
35293 Archive bit is not always set when file is changed
32427 MAC OSX SMB clients experience slowness when browsing directories on shares that have Anti Virus enabled. OSX is reading the file data instead of only its metadata.
29899 If there is a local and NIS/LDAP user with the same name (and different UIDs), creating a quota rule for this user affects only the local user UID and does not limit the NIS/LDAP user UID FS76x0
29567 After upgrade to v4 performance is negatively impacted for some time. Following the upgrade a policy kicks in, that frees inodes that were previously occupied by deleted small files. This is causing the system cache to fill, impacting performance. This is a one-time activity.
28334 Win8/10 clients cannot directly access the .snapshots folder, e.g. \\fluidfs\share\\.snapshots from Windows Explorer. Clients should access snapshots using the "Previous Versions" tab
27944 SACL audit events do not show in EM Use FluidFS CLI, e.g. "events auditing summary-list LastDay"
27204 AIX 7.1 clients cannot mount SMB shares as they use ANSI encoding while FluidFS only supports UNICODE encoding.
27105 In some conditions, adding a 3rd appliance does not scale-out the system
27103 Enabling/Disabling read-only access to a replica container does not update the Group Manager GUI FS76x0
24825 If SMB max version is set below SMBv3 and SMBv3 Encryption is enabled, access is denied from all SMB clients (regardless of SMB version). SMBv3 Encryption should be enabled only if the max SMB protocol version is at least SMBv3.
24036 Failure to configure quota directory (if parent directory previously was quota directory) delete and recreate the directory (it must be empty anyway to become quota directory)
23995 If new AD domain was created within the forest, and automatic user mapping is enabled, FluidFS will not map user identities (UID - SID) for users in the new domain and will map them to "guest/nobody" instead leave and join domain to refresh the FluidFS forrest/domains cache
20846 CLI Login Banner is not displayed

Item ID Problem Description Product Filter Workaround Release where fixed
x0002 Expanding the NAS pool with LUNs of sector size greater than 512 (e.g. 4KB) fails and stucks the system. FS76x0 Starting from version 9.03 the EqualLogic firmware prevents using such LUNs to expand the NAS pool, and is therefore strongly recommended. If already there, FluidFS Support should be contacted.
45777 Performance might be affected if AD is used as LDAP server and many (thousands) of groups have no gidNumber (i.e. Windows-only groups).
45763 When Hard Quota is exceeded writes to existing file is truncated without error message 6.0.110054
45745 When client belongs to multiple netgroups, NFS export access is evaluated alphabetically, by netgroup name, and may lead to unexpected behavior.
45740 FluidFS systems accessed via Layer-3 (IP-based, as oppose to standard, MAC-based) switches are likely to provide disruptive service. Assuming it is accessed via a standard Layer-2 (MAC based) switch, FluidFS can consistently assign and service different clients specifying same FluidFS VIP, with different FluidFS ports (MAC addresses). Layer-3 switches disrupt this scheme, by dynamically and continuously imposing a 1:1 mapping between an IP address (e.g. VIP) and a single MAC address. Specifically, an IP packet sent by a FluidFS system will cause the Layer-3 switch to direct ALL traffic to this IP (VIP) to the source switch port. If Layer-3 switch cannot be avoided, a partial workaround may be applied: using FluidFS GUI/CLI, manually map all {client-IP, VIP} pairs to FluidFS ports, where all pairs specifying same VIP are mapped to the same port. The drawbacks: 1. It will not survive a failover scenario, where FluidFS will not maintain the mapping between VIPs and FluidFS ports. 2. It is not practical for environments with many local clients. (Remote clients can be handled by mapping the router-IP as client-IP).

Known issues

Item ID Problem Description Product Filter Workaround Release where fixed
x0002 Expanding the NAS pool with LUNs of sector size greater than 512 (e.g. 4KB) fails and stucks the system. FS76x0 Starting from version 9.03 the EqualLogic firmware prevents using such LUNs to expand the NAS pool, and is therefore strongly recommended. If already there, FluidFS Support should be contacted.
45777 Performance might be affected if AD is used as LDAP server and many (thousands) of groups have no gidNumber (i.e. Windows-only groups).
45763 When Hard Quota is exceeded writes to existing file is truncated without error message 6.0.110054
45745 When client belongs to multiple netgroups, NFS export access is evaluated alphabetically, by netgroup name, and may lead to unexpected behavior.
45740 FluidFS systems accessed via Layer-3 (IP-based, as oppose to standard, MAC-based) switches are likely to provide disruptive service. Assuming it is accessed via a standard Layer-2 (MAC based) switch, FluidFS can consistently assign and service different clients specifying same FluidFS VIP, with different FluidFS ports (MAC addresses). Layer-3 switches disrupt this scheme, by dynamically and continuously imposing a 1:1 mapping between an IP address (e.g. VIP) and a single MAC address. Specifically, an IP packet sent by a FluidFS system will cause the Layer-3 switch to direct ALL traffic to this IP (VIP) to the source switch port. If Layer-3 switch cannot be avoided, a partial workaround may be applied: using FluidFS GUI/CLI, manually map all {client-IP, VIP} pairs to FluidFS ports, where all pairs specifying same VIP are mapped to the same port. The drawbacks: 1. It will not survive a failover scenario, where FluidFS will not maintain the mapping between VIPs and FluidFS ports. 2. It is not practical for environments with many local clients. (Remote clients can be handled by mapping the router-IP as client-IP).

45740 FluidFS systems accessed via Layer-3 (IP-based, as oppose to standard, MAC-based) switches are likely to provide disruptive service. Assuming it is accessed via a standard Layer-2 (MAC based) switch, FluidFS can consistently assign and service different clients specifying same FluidFS VIP, with different FluidFS ports (MAC addresses). Layer-3 switches disrupt this scheme, by dynamically and continuously imposing a 1:1 mapping between an IP address (e.g. VIP) and a single MAC address. Specifically, an IP packet sent by a FluidFS system will cause the Layer-3 switch to direct ALL traffic to this IP (VIP) to the source switch port. If Layer-3 switch cannot be avoided, a partial workaround may be applied: using FluidFS GUI/CLI, manually map all {client-IP, VIP} pairs to FluidFS ports, where all pairs specifying same VIP are mapped to the same port. The drawbacks: 1. It will not survive a failover scenario, where FluidFS will not maintain the mapping between VIPs and FluidFS ports. 2. It is not practical for environments with many local clients. (Remote clients can be handled by mapping the router-IP as client-IP).

45740 FluidFS systems accessed via Layer-3 (IP-based, as oppose to standard, MAC-based) switches are likely to provide disruptive service. Assuming it is accessed via a standard Layer-2 (MAC based) switch, FluidFS can consistently assign and service different clients specifying same FluidFS VIP, with different FluidFS ports (MAC addresses). Layer-3 switches disrupt this scheme, by dynamically and continuously imposing a 1:1 mapping between an IP address (e.g. VIP) and a single MAC address. Specifically, an IP packet sent by a FluidFS system will cause the Layer-3 switch to direct ALL traffic to this IP (VIP) to the source switch port. If Layer-3 switch cannot be avoided, a partial workaround may be applied: using FluidFS GUI/CLI, manually map all {client-IP, VIP} pairs to FluidFS ports, where all pairs specifying same VIP are mapped to the same port. The drawbacks: 1. It will not survive a failover scenario, where FluidFS will not maintain the mapping between VIPs and FluidFS ports. 2. It is not practical for environments with many local clients. (Remote clients can be handled by mapping the router-IP as client-IP).

x0002 Expanding the NAS pool with LUNs of sector size greater than 512 (e.g. 4KB) fails and stucks the system.

45740 FluidFS systems accessed via Layer-3 (IP-based, as oppose to standard, MAC-based) switches are likely to provide disruptive service. Assuming it is accessed via a standard Layer-2 (MAC based) switch, FluidFS can consistently assign and service different clients specifying same FluidFS VIP, with different FluidFS ports (MAC addresses). Layer-3 switches disrupt this scheme, by dynamically and continuously imposing a 1:1 mapping between an IP address (e.g. VIP) and a single MAC address. Specifically, an IP packet sent by a FluidFS system will cause the Layer-3 switch to direct ALL traffic to this IP (VIP) to the source switch port. If Layer-3 switch cannot be avoided, a partial workaround may be applied: using FluidFS GUI/CLI, manually map all {client-IP, VIP} pairs to FluidFS ports, where all pairs specifying same VIP are mapped to the same port. The drawbacks: 1. It will not survive a failover scenario, where FluidFS will not maintain the mapping between VIPs and FluidFS ports. 2. It is not practical for environments with many local clients. (Remote clients can be handled by mapping the router-IP as client-IP).

22239 The Microsoft security patch MS15-027 (https://support.microsoft.com/en-us/kb/3002657), breaks NTLM authentication for clustered solutions such as FluidFS, as well as for other cluster-based NAS products. The patch mandates NTLM authentication requests to provide computer names identical to the AD account names, otherwise the authentication will fail. Symptoms: Following the patch installation on Domain Controllers, users can't access SMB shares. Systems properly using Kerberos authentication are NOT affected by this security patch. Ensure that FluidFS clients and server properly authenticate using Kerberos (to avoid NTLM fallback). All below requirements must be met: 1. Clients should use the FluidFS DNS name (and not the IP address) to access shares 2. The DNS FluidFS name is identical to the AD FluidFS SPN. There are 3 alternatives to achieve that: a.

45740 FluidFS systems accessed via Layer-3 (IP-based, as oppose to standard, MAC-based) switches are likely to provide disruptive service. Assuming it is accessed via a standard Layer-2 (MAC based) switch, FluidFS can consistently assign and service different clients specifying same FluidFS VIP, with different FluidFS ports (MAC addresses). Layer-3 switches disrupt this scheme, by dynamically and continuously imposing a 1:1 mapping between an IP address (e.g. VIP) and a single MAC address. Specifically, an IP packet sent by a FluidFS system will cause the Layer-3 switch to direct ALL traffic to this IP (VIP) to the source switch port. If Layer-3 switch cannot be avoided, a partial workaround may be applied: using FluidFS GUI/CLI, manually map all {client-IP, VIP} pairs to FluidFS ports, where all pairs specifying same VIP are mapped to the same port. The drawbacks: 1. It will not survive a failover scenario, where FluidFS will not maintain the mapping between VIPs and FluidFS ports. 2. It is not practical for environments with many local clients. (Remote clients can be handled by mapping the router-IP as client-IP).

22239 The Microsoft security patch MS15-027 (https://support.microsoft.com/en-us/kb/3002657), breaks NTLM authentication for clustered solutions such as FluidFS, as well as for other cluster-based NAS products. The patch mandates NTLM authentication requests to provide computer names identical to the AD account names, otherwise the authentication will fail. Symptoms: Following the patch installation on Domain Controllers, users can't access SMB shares. Systems properly using Kerberos authentication are NOT affected by this security patch. Ensure that FluidFS clients and server properly authenticate using Kerberos (to avoid NTLM fallback). All below requirements must be met: 1. Clients should use the FluidFS DNS name (and not the IP address) to access shares 2. The DNS FluidFS name is identical to the AD FluidFS SPN. There are 3 alternatives to achieve that: a. (Preferred method) Change the cluster name to match the DNS hostname. (Leave domain, rename cluster, rejoin domain). This is somewhat invasive as authentication is broken when out of the domain. b. Add SPNs to the AD computer object of the FluidFS cluster that match the DNS hostname. The folowing SPNs should exist: HOST/, HOST/, nfs/, nfs/. See https://technet.microsoft.com/en-us/library/cc731241.aspx for managing SPNs. c. Change the DNS FluidFS hostname to match the FluidFS cluster name. This is very invasive as clients will have to start using new name for FluidFS. 3.

21199 Cannot create ADS for share root folder: INTERNAL_ERROR returned. 4.0.200700
20888 In version 3, SMB home shares could reside on folders in UNIX volumes. Due to the addition of the "automatic home folder creation" feature in FluidFS v4, and since this feature is automatically enabled on upgrade, FluidFS v4 upgrades are rejected if SMB home shares reside on a UNIX volume. 4.0.100714
20848 After upgrade to v4, shares went down and events like "Due to SMB high resource usage suspend receiving SMB." are issued the problem happens when system is configured to update access time for every file access. Configuring the volumes to update access times at lower granularity will resolve the issue. 4.0.100714

Assuming it is accessed via a standard Layer-2 (MAC based) switch, FluidFS can consistently assign and service different clients specifying same FluidFS VIP, with different FluidFS ports (MAC addresses). Layer-3 switches disrupt this scheme, by dynamically and continuously imposing a 1:1 mapping between an IP address (e.g. VIP) and a single MAC address. Specifically, an IP packet sent by a FluidFS system will cause the Layer-3 switch to direct ALL traffic to this IP (VIP) to the source switch port. If Layer-3 switch cannot be avoided, a partial workaround may be applied: using FluidFS GUI/CLI, manually map all {client-IP, VIP} pairs to FluidFS ports, where all pairs specifying same VIP are mapped to the same port. The drawbacks: 1. It will not survive a failover scenario, where FluidFS will not maintain the mapping between VIPs and FluidFS ports. 2. It is not practical for environments with many local clients. (Remote clients can be handled by mapping the router-IP as client-IP).
