Expand InsightIQ local datastore

Hello Jacob,

It doesn't look like this question has been answered. I would suggest to open up a support ticket so you can get this sorted out. Please let us know what you find out!

Hi Jacob, what you're asking is doable.  But I highly recommend working with support team b/c improper editing of configuration files can corrupt the VM.

I have noticed on the InshightIQ VM that the local data store (local - 63GB) becomes full almost every month (FSA is turned on) and I use to regain space by deleting "Per file IFS Operation Counters" from the configuration settings, data set management. If that will not work for you, then you can expand the data store by either pointing it to NFS export space from Isilon or expand the data store by presenting a new disk to the VM. Scan the new disk and mount it on a temporary mountpoit call it /datastore1 for example. (Use CLI). Then stop the insightIQ process. ( #sudo stop insightiq ).Copy all the data from /datastore to /datastore1 using any unix utility. cp, cpio, tar etc. (# cp -r /datastore /datastore1). Once the copy is done compare the folder sizes and if it looks good, unmount new & old disks from the mount point and mount the new disk as /datastore ( also edit fstab to make it permanent). Start the insightIQ service or reboot the host and it should work fine. I will keep a backup of the VM though and test it.

If you had an external NFS export (not on the Isilon), that would be the preferred option. 

Yes, I agree most will put the export on the Isilon cluster itself.  Please note that I mentioned "generally" recommended.

Keep in mind, generally it isn't recommended to use an NFS export on the cluster you are also monitoring.

new recommendation ? It sure is available as an option in InsightIQ interface and working with support i wasn't told not to use it.

Would the reason for this, just be extra load on the cluster?

I usually save storage space by deleting the configuration form insightIQ appliance GUI.

Setting --> Monitored cluster -> configure --> action delete or disable unwanted

Data Set Configuration

In answer to the original question, there is nothing "special" about the IIQ appliance and so the same rules that apply to expanding space for a generic Linux VM apply here.

The simplest way to do this, and what I would recommend is as follows.

1. Shut down the VM.
2. Snapshot the VM (so you can go back if you make a mistake).
3. Add a new larger disk to the VM.
4. Boot up the VM.
5. Login as administrator, sudo su
6. Create a filesystem on the new drive (either create an MSDOS partition table or just use the whole LUN).
7. Stop InsightIQ (run "iiq_stop").
8. mv /datastore /datastore.old
9. mkdir /datastore
10. mount the new LUN onto /datastore and add it to /etc/fstab
11. cp -ax /datastore.old/* /datastore
12. iiq_start
13. verify InsightIQ is working
14. rm -rf /datastore.old

HTH,

Tim
