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 export/import... did the digest command, which returned the proper results. However when I ran a zpool status I expected to see check sum errors. There were no errors listed. I then ran a scrub which detected the corruption and appears to have fixed it. So to me it looks like the raidz worked in that it return the proper results to me but: 1) It did not seem to report the corruption in the status... 2) Doesn''t appear to fix the errors "on the fly"... had to do a "scrub" to correct... Just curious if this is the expected behavior... This message posted from opensolaris.org
