I did a quick search but couldn't find anything about this little problem. I have an X4100 production machine (called monster) that has a J4200 full of 500GB drives attached. It's running OpenSolaris 2009.06 and fully up to date.
It takes daily snapshots and sends them to another machine as a backup. The sending and receiving is scripted and run from a cronjob. The problem is that some of the snapshots disappear from monster after they've been sent to the backup machine. Example: [i]sh...@monster:/$ zfs list -t snapshot | grep local@ ... mpool/lo...@zfs-auto-snap:daily-2009-07-02-00:00 64.5K - 176K - mpool/lo...@zfs-auto-snap:daily-2009-07-03-00:00 76.5K - 171K - mpool/lo...@zfs-auto-snap:daily-2009-07-05-00:00 59.8K - 173K - mpool/lo...@zfs-auto-snap:daily-2009-07-06-00:00 59.8K - 173K - sh...@chucky[11:53:46]:/$ zfs list -t snapshot | grep local@ .... mpool/lo...@zfs-auto-snap:daily-2009-07-01-00:00 35K - 92K - mpool/lo...@zfs-auto-snap:daily-2009-07-02-00:00 36K - 93K - mpool/lo...@zfs-auto-snap:daily-2009-07-03-00:00 43.5K - 89K - mpool/lo...@zfs-auto-snap:daily-2009-07-04-00:00 0 - 90K -[/i] As you can see the snapshot for 2009-07-04 exists on chucky (the backup machine) zpool history shows the snapshot was taken: [i]sh...@monster:/$ pfexec zpool history mpool | grep 2009-07-04 2009-07-04.00:00:02 zfs snapshot mpool/lo...@zfs-auto-snap:daily-2009-07-04-00:00 2009-07-04.00:00:04 zfs snapshot -r mpool/local/vmwaremachi...@zfs-auto-snap:daily-2009-07-04-00:00 2009-07-04.00:00:05 zfs snapshot -r mpool/local/cvsr...@zfs-auto-snap:daily-2009-07-04-00:00 2009-07-04.00:00:06 zfs snapshot -r mpool/proje...@zfs-auto-snap:daily-2009-07-04-00:00 2009-07-05.00:05:09 zfs destroy mpool/lo...@zfs-auto-snap:daily-2009-07-04-00:00 2009-07-05.00:05:12 zfs destroy mpool/local/cvsr...@zfs-auto-snap:daily-2009-07-04-00:00[/i] and the script did not produce any errors: [i]pfexec /usr/sbin/zfs send -I mpool/lo...@zfs-auto-snap:daily-2009-07-03-00:00 mpool/lo...@zfs-auto-snap:daily-2009-07-04-00:00 | ssh sh...@chucky pfexec /usr/sbin/zfs recv mpool/local[/i] Any ideas? -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
