Hi all,
I recently noticed that snapvault is failing because there is not enough space on the primary filer volume, and thus snapshots are automatically removed to free up space (otherwhise the lun that is in this volume will probably run full with the lun failing).
To prevent snapvault from failing I want to make the volume on the primary bigger.
The volume is on aggr3_fc
delng153> df -Ah
Aggregate total used avail capacity
aggr3_fc 4675GB 4104GB 571GB 88%
aggr3_fc/.snapshot 246GB 231GB 14GB 94%
So there seems to be plenty of space to resize the volume.
However what I wonder if there is any recommended percentage of space I should keep free on the aggregate to keep the filer fully functional (as in both functionality and performance).
Furthermore I wonder if I can size the volume down later if necessary without any interuptions or if this is only possible in very specific cases.
Note that I am using flexvols.
Thanks in advance for any help!
