We have customers using SRDF with ZFS, but one issue that comes up is failing *back* to the original host. If that host never goes down (panic, reboot), then the pool is already imported on the original host, and when you try to fail back, there will be a mismatch between what's in memory vs. what's on disk (assuming the pool was modified by the secondary host). See: 6695687 Force-export a ZFS pool Ugly workaround is to purposely reboot the original host. And you will want: 6282725 hostname/hostid should be stored in the label http://blogs.sun.com/erickustarz/en_US/entry/poor_man_s_cluster_end which will be in s10u6. eric _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
