Solved: Can't delete volume

garges · ‎2020-08-11

Pardon my naivete, I"ve not used NetApp much. I've inherited an old FAS8040 running OnTap 8.2.4. It's out of support and the only thing I need to do is securely erase the disks prior to system disposal. So I want to run disk sanitize. To do that (as I understand it) I have to delete the aggregates and make all the disks spares. So to do that I need to delete the volumes. There were 481 and I was able to delete all but 53 of them. They give this error:

dco-prod-netapp::*> volume delete -vserver es-prod-netapp-vs2 -volume urcdev_data_a_vol

Error: command failed: Volume urcdev_data_a_vol in Vserver es-prod-netapp-vs2 must be offline to be deleted.

Error: command failed: [Job 39372] Job failed: Failed to delete junction from volume rootvol_esprd_vs2 on Vserver es-prod-netapp-vs2. Reason: The volume or plex is offline.

Any pointers would be appreciated.

Thanks to everyone that offered a solution. Still could not resolve it though. We decided to get a bigger hammer for this problem. Literally, we're just going to physically destroy the disks.

Hello,

This could be due to different reason, but you can check couple things listed below:

1. Check if you have any failed drive that belong to the aggr in question.

2. Check the status of the aggr (online, offline foreign....)

3. Check the volume and if you have any clone.

Thanks

There were 2 failed drives, but they were not listed as part of any aggregate or spares.

Tried this both when the aggregate was online and offline. Same result.

There were 5 FlexClones listed but I didn't see any way to delete them.

You have to unmount the volume from the namespace first. It says as much here:

Warning: Volume "urcdev_data_a_vol" on Vserver "es-prod-netapp-vs2" must be unmounted before being taken offline or restricted.

So, do this:

- Online the volume

- Run "volume unmount" to unmount the junction path

- offline the volume

- delete the volume

Keep in mind that deleting the volume without -force will put the volume into the recovery-queue and won't free up space for 12ish hours:

If you want to zero all drives, just reboot the filer and push ctrl+c to interrupt boot menu. I believe there is an option there in 7-mode to wipe the drives. Option 4 will wipe then initialize with a new O/S.

Well...that's one way to do it!
