Hi all, I have several machines here that do automatic snapshotting via RSEs snapshot-tool (sysutils/freebsd-snapshot). I use a homemade script to incrementally transfer daily snapshots to a backup server. This runs fine with machines running 7.0-STABLE of Jun 08. However, I have one box with 7.1-PRERELEASE from Sep 08 showing the following error after some time (when trying to rotate the snapshots via the freebsd-snapshot tool): cannot destroy 'tank/www@daily.6': dataset is busy I fact I cannot do anything to the snapshot, neither destroy nor export (not even with "-f"), it is always "busy". The only chance to get away from this I found is to reboot the machine. After a reboot it is fine for some weeks, but then comes back with the same problem. Has anyone seen this before? Is there a fix or workaround available? Are there any improvements I could take profit of by upgrading to 7.2-stable? Right now the machine is in this state, so I could get some more information from it (if anyone tells me what to do :-). cu Gerrit
