One of my zfs pools is growing very large:
NAME SIZE ALLOC FREE CAP DEDUP HEALTH ALTROOT
zonepool01 556G 535G 21.2G 96% 1.00x ONLINE -
df -h
shows that the largest mount point on this pool has 6 files in the directory so files are not the issue.
I looked for old snapshots:
zfs list -t snapshot -o name -S creation | grep 2015 | grep zonepool01
zonepool01/server06/rpool/ROOT/solaris-3@2015-09-24-03:10:49
zonepool01/server06/rpool/ROOT/solaris-3/var@2015-09-24-03:10:49
zonepool01/server05/rpool/ROOT/solaris-3@2015-09-24-03:10:45
[...]
zonepool01/server28/rpool/ROOT/solaris-3@2015-08-12-17:02:10
zonepool01/server27/rpool/ROOT/solaris-0/var@2015-08-12-16:55:37
zonepool01/server27/rpool/ROOT/solaris-3@2015-08-12-16:55:37
The last time I tried to delete snapshots I messed up my boot and system. To prevent this, I need to know:
- How do I know what is old and obsolete?
- How do I know what is not referenced by other snaps?
- How do I stop this auto snap feature?
