Hi Robert, We've experienced luck with flaky SATA drives in our STK array by unseating and reseating the drive to cause a reset of the firmware. It may be a bad drive, or the firmware may just have hit a bug. Hope its the latter! :-D I'd be interested why the hot-spare didn't kick in. I thought

After watching the flash demo on self-healing I thought I would try the experiment myself. Instead of a mirror, i created a raidz pool made up of 9 disks. I copied a large file into the pool. Then, like in the demo, I corrupted one of the disks with a dd command. I did the digest... I did the

[zfs-discuss] Replacing a drive in a raidz2 group
