How to free some space on a volume to quiesce a snapmirror (to delete it) ?
2013-03-04 09:51 AM
Hello, i'm having some trouble freeing space on a FAS2220 Volume.
I've got two FAS2220 which are snapmirroring / snapvaulting their data on the filerB of the other FAS2220.
All start by a broken lrep (replication destination failed to load the offset into the directory metadata) from a snapmirror baseline.
So i start deleting the failed qtree (snapmirror quiesce > snapmirror break > and finality deletion of the qtree).
All works great on the FAS2220 "A".
But on the FAS2220 "B" :
-I can't quiesce qtree volume because I don't get enough free space on my volume.
-I cant delete a snapshot because it seems busy/lock with snapmirror
-I dont get anymore freespace on the FAS2220 to growth my volume.
Any idea ?

snap list [volume name]
output: (for instance)
%/used %/total date name
---------- ---------- ------------ --------
25% ( 1%) 8% (0%) Feb 28 02:37 Daily.23
31% (11%) 12% ( 3%) Feb 12 02:37 Daily.28 (busy,LUNs)
36% (10%) 14% (3%) Feb 04 02:13 monthly.FB032008
lun snap usage -s [vol name] [busy snapshot name]
Snapshot - Daily.7
Snapshot - MR162008
Snapshot - Daily.8
Snapshot - Daily.9
this is an example of how it could be, however you have to delete all listed snapshots
snap delete -V [volume name] [snapshot name]
PS: you might set vol options snap reserve [vol name] a bit less, for instance 10% instead of default 20 (if it set) it gives you a bit of "breathing" space on volume
worked for me hope it helps
