I recovered the pool by doing export, import and scrub. Apparently you could export pool with a FAILED device, and import will restore labels from backup copies. Data errors are still there after import, so you need to scrub pool. After all that the filesystem is back with no errors/problems.
It would be nice if documentation mention this, namely that before trying to replace disks or restoring backups, you could try to export/import. Also, it is not clear what "zpool clear" actually clears (what a nice use of word "clear"!). It does not clear data errors recorded within the pool. In my case they were registered when I tried to read data from pool with one device marked as FAILED (when in fact only label was corrupted, the data itself was OK), and disappeared upon scrub. So my thanks go to people on Internet who share their findings about zfs, and zfs developers who made such a robust system (I still think it's the best from all [free] systems I used). -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
