Hey world, I've got an AMD64 system on SVN r209893 of 8.1, with a standard GENERIC config [except that DDB and DTRACE are turned on]. I've got a 10-disk RAID-Z2, made on 8.0-RELEASE, that had two disks in it fault, one after another. I did a zpool replace on each of them, and it was happily resilvering for about 12 hours, and got to 25% done at 12 hours. I'll let the following output of zpool status speak for itself: # zpool status -v pool: bukkit state: DEGRADED status: One or more devices has experienced an error resulting in data corruption. Applications may be affected. action: Restore the file in question if possible. Otherwise restore the entire pool from backup. see: http://www.sun.com/msg/ZFS-8000-8A scrub: resilver in progress for 23h15m, 25.16% done, 69h11m to go config: NAME STATE READ WRITE CKSUM bukkit DEGRADED 0 0 28 raidz2 DEGRADED 0 0 56 replacing DEGRADED 0 0 0 da1 FAULTED 0 244K 0 corrupted data da11 ONLINE 0 0 0 274G resilvered da9 ONLINE 0 0 0 333M resilvered da1 ONLINE 0 0 0 348M resilvered da8 ONLINE 0 0 0 333M resilvered da0 ONLINE 0 0 0 348M resilvered replacing DEGRADED 0 0 0 12471449581279369829 FAULTED 0 234K 0 was /dev/da7 da2 ONLINE 0 0 0 274G resilvered da6 ONLINE 0 0 0 348M resilvered da10 ONLINE 0 0 0 333M resilvered da5 ONLINE 0 0 0 349M resilvered da7 ONLINE 0 0 0 333M resilvered So, 12 hours have progressed, and the resilver hasn't. zpool iostat 1 reports activity whenever I do any IO on any of the filesystems contained in the pool, but otherwise is just a straight line of 0 activity. dmesg has nothing interesting - the last messages in it are from when I inserted the replacement disks and it noted the secondary GPT tables were wrong. I could restart it, but it's not clear to me that this would help anything. Thanks, - Rich
