ReadyNAS X6 with repeated disk failures on same channel
I have an aging X6 (original one, PN: RNX6S2000-009). Several months back it began occasionally sending "RAID event detected" emails ("RAID sync started on volume C.", then "RAID sync finished on v...
mdgm, I tried a few things:
Not having a fresh drive readily available, I took one of the 3 drives I have (one that tested "good" with SeaTools) and ran it through the long-version SeaTools test (good) and then wiped the disk with SeaTools (low-level format, I think?) (Still trying to find a way to run SpinRite or borrow a fresh drive, but thought I'd try this for now.)
I installed this disk on Channel 2, and the array appeared to rebuild (and again, worked for several days).
In the meantime I noticed another serious problem (possibly related - not sure). When trying to power the unit back up, it had trouble powering on. When I flipped the hard power switch (rocker switch on back of unit) the NAS would power on for about half a second (fan and blue LED) then stop/go silent. By jiggling the power supply cord and repeatedly flipping the rocker switch on, I was able to get it to power on. (I tried a couple different outlets and a couple different power cables to rule this out.) It seemed like if it got past the initial disk spin-up, it would continue running, but about 4 out of 5 attempts to power up never made it past the first 1/2 second.
So this sounds like a power supply problem/PSU failure to me. I have no idea if this would explain the drive failures (or false drive failures) I've been having.
I came home after a couple days to find the unit powered off (no warning emails, etc.) I powered it back on and it did a RAID re-sync successfully. Another day later I got the dreaded "producing I/O errors" and "disk fail event" emails related to Channel 2. Then the two "Automatic Shutdown" emails (this time it sent 8 copies of each email ... weird).
How would you proceed at this point? Replace just the PSU or replace the whole box (with cheapest available used X6) and move the disks over? Is it true that I can move my disks to any SPARC-based ReadyNAS and preserve my data? (Even if the array is in a degraded state now?)
Thanks again for your gracious help!
