How space is released after volume deletion in ONTAP 8.3.1?
I quisced/break/deleted Snapmirror destination. I did nothing on the source. Then offlined/deleted destination volume, volume disappeared from 'volume show', but no space was released.
I found the following message in logs:
INFORMATIONAL wafl.vvol.renamed: Volume 'vsCIFS_foto_mirror@vserver:3baa94ea-039d-11e5-acfe-00a0987ca09e' renamed to 'vsCIFS_foto_mirror_1035@vserver:3baa94ea-039d-11e5-acfe-00a0987ca09e'
I checked space in 8 hours (before midnight), no changes, still space was not released.
But it in the morning space finally released in aggregate.
I found this at 4 AM (in 13 hours after deletion)
INFORMATIONAL wafl.vvol.destroyed: Volume vsCIFS_foto_mirror_1035@vserver:3baa94ea-039d-11e5-acfe-00a0987ca09e destroyed.
In 7-mode a background scanner started after deletion and you could see how space is released.
Can anybody explain how this works in cDOT?
