[zfs-discuss] (Meta)Data corrupted on multiple triple mirrors
Hello.
3 month old pool hosted across two SAS JBODs w/ SATA disks on an x4170m2
running Solaris 11 SRU6.6, ran a scrub and I got this:
pool: zdata
state: ONLINE
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
scan: scrub repaired 0 in 19h51m with 1 errors on Fri Nov 9 18:54:22 2012

How did this happen and how screwed are we? I''ve sent a bug report to
Oracle too..
Log is an OCZ Vertex2EX (slc&supercap), cache is an Intel 510.
Host has been rebooted 3 times after the pool was created, all the same
day as creation.
