This was indeed caused by the old boot environment. This is how to solve it: - disable snapshots on the old boot environment: pfexec zfs set com.sun:auto-snapshot=false rpool/ROOT/opensolaris-1 - clear zfs snapshot services pfexec svcadm clear auto-snapshot:frequent pfexec svcadm clear auto-snapshot:hourly pfexec svcadm clear auto-snapshot:daily - launch the time slider and enable zfs snapshots on the appropriate systems - check the services are online: svcs ... online 21:50:20 svc:/system/filesystem/zfs/auto-snapshot:hourly online 21:50:26 svc:/system/filesystem/zfs/auto-snapshot:frequent online 21:50:36 svc:/system/filesystem/zfs/auto-snapshot:daily Hurray ! -- Axelle -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
