Hi,
I've been using freenas for a while now and generally not had any significant problems. Until a few days ago! I recommended that a friend get a freenas box as its cheap (compared to things like QNAP) and you get more bang for your buck. So he purchased an HP proliant N40L I think or P... and installed 8Gb of ECC ram and put in 4 hard drives. At the point he was running 9.2.1.5, then upgraded to 9.2.1.6... and now finally is running .8.. He has one pool RAIDZ1, one jail running crashplan, one user.. and all is very simple...
only the other day the crash plan stopped working, so i suggested he reboot... but now it refused to boot. this was all a bit weird... so i suggested he re-image a new USB stick with 9.2.1.8 which he did. The machine boots just fine, now when i auto import the volume. it reboots... immediately...
if i run
zpool import -f -R /mnt tank
the machine crashes immediately...
if I run
zpool import -f -R /mnt -o rdonly=on tank
then the pool mounts, and all the data is there... this is good... but my questions is this...
1) what do I do now... I don't really have the option 'just yet' to copy the data of the NAS to something else and recreate the pool.. which i guess is the straightforward easy option.. so apart from this, is there anything else that I can try...
2) Why did this happen... I've had a lot of faith in ZFS .. but there are other posts about this thing happening... and it is rather disconcerting.. given that there are no rescue tools available. I'm running ECC ram... system is up to spec, freenas is uptodate.. there is loads of space on the pool... technically I don't think i've done anything wrong... cyberjock may not agree with me on that one.. but i do have ECC!!!!!!!!
