Kernel Panic
I received a new unit for my PSU failed NV+ today (FW 4.1.7).
Plugged in the 4 disks (in the right order) and powered on.
Came back a while later to see "Kernel Panic" on the LCD.
Powered off and on to see what the cause was, and heard the hard drives going ker-chick, ker-chick about a dozen times.
So that seems like a disk problem on maybe more than one.
Tested with a spare 1T drive and it started and formatted for XRaid with no issues.
So more likely it's my old disks.
Reinstalled the old drives.
Using the paperclip and reset button.
FW reinstall succeeded - but made no difference.
Factory reset worked - restarted and selected XRaid and left to do its thing.
Can a bad drive cause a Kernel Panic?
I guess Colonel Panic is related to General Protection.

- Yes, flakey drive can cause a Kernel Panic.
Try booting without one of the disks inserted. If still panic, replace that disk, and remove the next one. Power off between add/removing the disks. Eventually you should boot up successfully with a failed drive notice. The drive removed at that point was the cause of the panic, RMA time. - It was orignally a diskless NV+, so the drives are my problem.
Seagate Barracuda 7200.12 ST31000528AS installed 27/6/10 so out of warranty by nearly 3 months, and discontinued.
Replacement/upgrade 2T disks are hard to find with 60% of the HCL discontinued.
Only one drive on the HCL that is currently available is NAS rated by the manufacturer.
The hardware compatibility list doesn't keep up to date with manufacturers' changes.
e.g. the 5 year warranty RAID designed Hitachi HUA722020ALA330 appears to be replaced by the HUA723020ALA640
Western Digital WD RED WD20EFRX - £92 (3yr warranty) 24x7
Hitachi Ultrastar A7K2000 HUA722020ALA330 - discontinued
Hitachi 7K3000 HDS723020BLA642 - discontinued
Barracuda 7200.14 ST2000DM001 - £72 (1yr warranty)
Barracuda LP ST2000DL003 - discontinued
Caviar Green WD20EARX - £75 (1yr warranty)
Caviar Black WD2002FAEX - £130 (5 yr warranty)
Hitachi 7K2000 HUA722020ALA330 - discontinued
Samsung HD204UI Spinpoint F4 - discontinued
Barracuda LP ST32000542AS - discontinued
Barracuda XT ST32000641AS -discontinued - My advice on drives is to go with the WDC WD20EFRX.
Also I thought Seagate warranties back in 2010 were 3 years. You might use their warranty checker tool. However, they would send you a refurbished drive, and often don't replace it with the same model. So often I've done their RMA return, but used the replacement drive somewhere else...
BTW, a flakey SATA interface in the NAS could also be the cause. So it would be good to try Chirpa's procedure, and then confirm that it is in fact the disk. - I've tested in two different brand new RMS NAS with the same result.
Both work with a new drive in slot 1 and no other drives.
Both fail with Kernel Panic with the disk set form my old 01ABBF unit.
So I'll try pulling disks one at a time.
Pulling disk 2 reduced the clicking - but gave a bad firmware error I tried to reinstall using the reset button.
Reinstall appeared to work, but then gave a Panic.
So I'll try 3, 4, and 1 to see what if any works.
No difference, removing any one of the 4 disks and attempting to boot now gives a Kernel Panic.
If there are two dead disks the array is dead - and it's the backup of the backup (NAS3 backs up NAS2 which backs up NAS1) so I don't have to worry :o
Just buy a new set of drives, hard drives are (expensive) consumables.
Drives ordered - that's my Xmas present sorted!
