[zfs-discuss] Unable to destroy/rollback snapshot
I''ve been trying to rollback a snapshot but seem to be unable to do so. Can anyone shed some light on what I may be doing wrong? I''m trying to rollback from thumperpool/mnt at 200908271200 to thumperpool/mnt at 200908270100. 344 root at thumper1:~> zfs list -t snapshot | tail thumperpool/mnt at 200908261700 73.0M - 1.45T - thumperpool/mnt at 200908261800 72.0M - 1.45T - thumperpool/mnt at 200908261900 72.4M - 1.45T - thumperpool/mnt at 200908262000 71.9M - 1.45T - thumperpool/mnt at 200908262100 67.7M - 1.45T - thumperpool/mnt at 200908262200 67.5M - 1.45T - thumperpool/mnt at 200908262300 72.0M - 1.45T - thumperpool/mnt at 200908270000 71.0M - 1.45T - thumperpool/mnt at 200908270100 75.0M - 1.45T - thumperpool/mnt at 200908271200 0 - 1.45T - 345 root at thumper1:~> zfs list -t filesystem NAME USED AVAIL REFER MOUNTPOINT rpool 10.4G 446G 33K /rpool rpool/ROOT 757M 446G 21K legacy rpool/ROOT/solaris_u8 757M 446G 757M / rpool/export 6.39G 446G 23K /export rpool/export/home 6.39G 446G 6.39G /export/home rpool/opt 234M 446G 234M /opt thumperpool 6.72T 9.27T 48.8K /thumperpool thumperpool/export 11.7G 9.27T 48.8K /oldexport thumperpool/export/home 11.7G 9.27T 11.7G /oldexport/home thumperpool/mnt 6.70T 9.27T 1.45T /thumperpool/mnt 346 root at thumper1:~> zfs rollback thumperpool/mnt at 200908270100 cannot rollback to ''thumperpool/mnt at 200908270100'': more recent snapshots exist use ''-r'' to force deletion of the following snapshots: thumperpool/mnt at 200908271200 347 root at thumper1:~> zfs rollback -r thumperpool/mnt at 200908270100 cannot destroy ''thumperpool/mnt at 200908271200'': dataset already exists This is an X4500 running Solaris U8.
