I had some trouble installing a zone on ZFS with S10u4 (bug in the postgres packages) that went away when I used a ZVOL-backed UFS filesystem for the zonepath.
I thought I'd push on with the experiment (in the hope Live Upgrade would be able to upgrade such a zone). It's a bit unwieldy, but everything worked reasonably well - performance isn't much worse than straight ZFS (it gets much faster with compression enabled, but that's another story). The only fly in the ointment is that ZVOL level snapshots don't capture unsynced data up at the FS level. There's a workaround at: http://blogs.sun.com/pgdh/entry/taking_ufs_new_places_safely but I wondered if there was anything else that could be done to avoid having to take such measures? I don't want to stop writes to get a snap, and I'd really like to avoid UFS snapshots if at all possible. I tried mounting forcedirectio in the (mistaken) belief that this would bypass the UFS buffer cache, but it didn't help. -- Rasputin :: Jack of All Trades - Master of Nuns http://number9.hellooperator.net/ _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
