Dell FluidFS Version 5.0 FS8600 Appliance Firmware Update Guide
Performing Pre-Update Tasks
Complete the tasks in the following list before updating to FluidFS version 5.0.
- Change the FluidFS cluster name and NetBIOS name to match.
Make sure the cluster name contains fewer than 15 characters and does not begin with a number.
- Delete local user names that have a period as the last character. Recreate these accounts with different names.
- Stop all NDMP backup sessions.
If an NDMP backup session is in progress during the update, the temporary NDMP snapshot remains in place.
- Open additional ports on your firewarll to allow replication between replication partners.
- Make sure SMB shares and NFS exports have only alphanumeric characters in the Comment field.
- Make sure NAS volumes do not have the names in the following list.
These names are reserved for internal FluidFS cluster functions.
- .
- ..
- .snapshots
- acl_stream
- cifs
- smb
- int_mnt
- unified
- Any name starting with locker_
- Make sure local groups do not have the names in the following
list. These names are reserved for internal FluidFS cluster functions.
- Backup Operators
- Local Users
- nobody_group
- Users
- Make sure all the defined DNS servers are accessible using ping and dig (DNS lookup utility).
- Make sure the Active Directory domain controller is accessible using ping, and that the FluidFS cluster system time is in sync with the Active Directory time.
- Make sure the NAS controllers are running, attached, and accessible
using ping, SSH, and rsync.
Although the minimum requirement to update is that at least one NAS controller in each NAS appliance must be running, Dell recommends that all NAS controllers be running.
