Hello FreeNAS Community,
I have a FreeNAS-11.3-U2.1 server that is connected (via a SAS9217-4i4e HBA) to two Dell PowerVault MD1200 disk enclosures, each of which has 12 x 1.82 TiB hard disks. I've created 4 x Pools, each with 6 HDD RAIDz vdevs.
I don't know what really happened but out of a suddent 3 pools went into UNAVAIL status! In the attached syslog file, you would see many errors starting at Jul 18 17:53.
What do you expect the reason behind this problem? I thought it was a power problem that took the Dell MD1200s down but if that was the case why was one of the pools not affected at all?!
After clearing errors with "zpool clear", two pool went back online. The other pool required a reboot to get back to online status. After the reboot, it seems everything is ok with the data but "zpool status" reports errors with one of the pools resulting in data corruption although scrubbing that pool did not fix anything. Should I worry about these errors?:
Thanks in advance for your help!
Regards,
Shwan
