How to remove Primary Storage / NPE in Maintenance mode
Hi All,
Is there a way to remove the Primary Storage?
I’m running a clean devcloud on a VM with almost the latest code from the
Master branch (commit ba69ce0c8911eb7186774d2ddbae97483e65d48c from 3/19).
The only UI options I see for 2 Primary Storage instances I’ve added are:
- Enable Maintenance mode
- Edit (only allows storage tag edits)
States of both Storage elements are Up (one is NetworkFilesystem, another -
PreSetup). When I select a Maintenance mode it fails with the
NullPointerException. It looks very similar to CLOUDSTACK-1635.
Thanks,
-Vladimir

so cloudstack should be controlling your storage via the hypervisor. you'll
need to check the health of the storage via the hypervisor. see if youre
able to provision a vm to it.

This time I was unable to bring it up. It was failing with Out of memory
error.
But I noticed another set of exceptions prior to that - "Can not see
storage pool"
Please find the log attached.

care to post your management server logs, after trying to perform the
maintenance action. It should reveal an error and possibly clues as to why
it doesnt want to transition your storage.

care to post your management server logs, after trying to perform the
maintenance action. It should reveal an error and possibly clues as to why
it doesnt want to transition your storage.

Hi Ahmad,
Thanks for the reply. I have no VMs in this setup. I guessed that storage
removal option should be allowed after moving it into the maintenance mode,
but this operations fails and it is stuck in "Up" state :-)

If your primary storage were able to successfully transition into
maintenance mode, you'd be able to remove it. You'll need a second PS
attached to the cluster, so vm's can migrate offe storage that's going into
maintenance OR disable the zone and nuke the system vm's power down the
guest vm's wait for storage cleanup to run, then try the process of putting
the storage into maintenance and removing it.

If your primary storage were able to successfully transition into maintenance mode, you'd be able to remove it. You'll need a second PS attached to the cluster, so vm's can migrate off the storage that's going into maintenance OR disable the zone and nuke the system vm's power down the guest vm's wait for storage cleanup to run, then try the process of putting the storage into maintenance and removing it.
