I have a Acasis EC-7352 set to JBOD mode (Just Bunch Of Disks) so not trying to do hardware raid. (that's another story I abandoned)
I have 2 identical WD Ultrastar HUS726T6TALE 6TB hard drives.
I have (had) a working raid-1 that mounts and runs ok for a few weeks, seeming like earlier problems were in the past.Today I powered it up, and tried to mount it, but it failed.
After 5 minutes the computer froze up, no screen updates, no keyboard. Frozen.
Rebooted, and looked at /var/log/messages
Lots of errors, several call-Trace events.
I repeated the sequence and confirmed it is repeatable.
I have clipped the 5 minutes of /var/log/messages showing the attempts to mount the drives, the multiple Call-Trace events, right up to the system freezing. It is long and repetitive, but contains useful back trace I hope. See zip file.
Besides saying the enclosure firmware is garbage, despite being advertised as being compatible with linux, can anyone say why it crashes so badly? and anything I should try before tearing it apart and trying other solutions to get my data rescued?
Thanks
