Provisioning manager vFiler migrate fails with "volume exists on desitination" - won't refresh with dfm host discover

fletch2007 — Thu, 05 Jun 2025 07:06:33 GMT

Hi,

I'm deleting the existing volume on the snapmirror destination to make way for vFiler migrate to re-init the snapmirror.

But Provisioning Manager is erroring out in the vFiler migrate (see below) since it thinks the deleted volume is still existing on the destination.

I follow the suggestion to run dfm host discover <filer with deleted volume> and tried it several times via the MC refresh, but it will not clear.

Any ideas besides rebooting the DFM?

thanks

Hello fletch2007,

DFM doesn't immediately update its DB when some volumes are deleted from the filer. Even if you do numerous discoveries the DFM will retain the volume information for 1 hour. This is purposely done.

To get over your problem, you need not reboot the dfm server.

just do the following.

dfm volume delete <volume_name or ID>

to see the volumes do

dfm volume list <filer_name>

It will delete the volume info immediately from your DFM db and allow you to proceed.

I hope this helps.

warm regards,

Abhishek
