Working on a new implementation of InsightIQ. The default /datastore size
created by the OVA is 6.5GB, and we'd like to expand this. How do we expand
the local /datastore file system? We've already expanded the ESX datastore
that supports the InsightIQ VM.
Please note that we do NOT want to use NFS for /datastore. We want to
expand the local /datastore file system.
Thanks in advance,
Thank you for your question! To expand the datastore partition on InsightIQ, you will need to create a new virtual disk and move the data (if there is any.) If you have a login to EMC online support, you can follow the resolution in this Knowledge Base article:
If you do not have a login to EMC online support, send me a message and I can get the information you need. Please let me know if there is anything else I can do for you.
Thanks for the response. I do have access to support.emc.com, but following the link I get an "Access Denied" error.
Can you forward me the information?
Statistics from Isilon clusters are no longer being gathered. This issue applies to all virtual machine (VM) installations of InsightIQ.
The /var/log/insightiq.log file on the InsightIQ VM contains entries similar to the following:
2013-07-18 12:59:54,413 ERROR [insightiq.lib.cluster.errors] mycluster Cannot recover from exception - monitoring will not restart: Traceback (most recent call last):
2013-07-18 12:59:54,406 INFO [insightiq.lib.cluster.fact.pruning_monitor] Data store /net/smartconnect.mycluster.com/ifs/InsightIQDataSt
The amount of data being gathered for InsightIQ exceeds the allotted datastore size.
Perform the following steps to create a new, larger local datastore, configure InsightIQ to use the new datastore, and copy the existing data from the old datastore to the new datastore.
Reverting to the previous datastoreIf these changes need to be reverted, you can revert to the old /etc/fstab by running the folliwng command and then rebooting:
sudo cp -v /etc/fstab.bak /etc/fstab
rebootAlternatively, you can shut down and revert to a snapshot if one was taken.
Remove the old datatstoreAfter confirming that the new datastore works as expected and contains all the desired historical data, you can remove the old datastore:
Additional informationRelated article:
Can we get this information added to the InsightIQ installation guide? At the very least can we get some details added about disk space layout for local directories? Without this KB there is no way to plan how to build the InsightIQ VM structure.
Further, is there a reason that the command "parted" is not in the CentOS release being used for the InsightIQ VM?
Thank you for your feedback. I will pass the documentation request along to the team.
As for the "parted" command, the OVA was designed to be very stripped down and easily packaged by engineering, and I cannot speak to their decision to remove certain commands over others; however, you can install any command you would like through the "yum" package manager. I use this functionality a lot myself to add commands to my OVAs to customize them to my needs.
Please let me know if you have any additional questions or concerns.
