Hi,
I have a big problem with my NAS.
The first issue was a Degraded pool (2 disks in Raid1-ZFS), with one disk REMOVED. I tried to put it back online but it was impossible.
OK, I don't tell the whole story since that moment (several tries+ I lost the other disk stupidly...). Nevermind.
All I'd like now is to know if I have a chance to get back the data. Here is the current situation:
System Information
Hostname freenas.local
Build FreeNAS-9.1.1-RELEASE-x86 (a752d35)
Platform AMD Sempron(tm) Processor LE-1250
Memory 1903MB
Initially, two disks 2 TB in RAID1
ZFS File system (I know, I'd have needed more memory)
OS on USB stick
Behavior at boot:
OS starts. No anomaly except:
a CAM error, like:
Then, the last thing I can see are:
Behavior at boot
Then, the system freezes.
Behavior at boot, disk being disconnected
I've then tried to boot without any disk, then plug it when the OS is ready.
Here is the a part dmesg output
dmesg(1)
Then, I plug the disk and get:
