It has had a number of XFS filesystems over the years for media storage,
and except for one major flameout a few years ago when I had a PATA
interface lose a cable wire -- which Dave politely helped me dig out from
under -- it's been quite reliable.
About halfway through June, a surge apparently put a hurtin on our 7 year
old Antec power supply, and it slowly failed over the next couple weeks.
In the process, its 12V rail apparently went first; this is my perceived
cause for a 2TB deathstar giving me a SMART failure for Spin Retry Count.
But the week before that, the 1TB deathstar started actually dropping
sectors, and I copied all its data onto a freshly bought Seagate 3TB.
4 days later, when I noticed that SMART had tripped on the 2TB, I copied
all its data to the same new 3TB, which didn't quite fill, and that drive
has been well behaved.
The *earlier* 3TB, though, hs been giving me trouble; it's filesystem has
had some deeply buried problem that neither mounting nor running xfs_repair
has been able to fix -- and it's probably been exacerbated by the fact
that if I inadvertantly boot the box with that filesystem in fstab, and
it tried to mount it while broken, a) it locks up that disk channel and
b) the machine won't reboot, forcing me to hit the big orange switch.
That's where I am right now: the drive was throwing a kernel oops if I
mounted it, and xfs_repair would just lock up. I had to do a -L on
it, after which it would mount and unmount cleanly, and xfs_repair runs
and finds problems, but then fails an assert at the end and dies.
Here's that entire repair run:

Phase 1 - find and verify superblock...
Not enough RAM available for repair to enable prefetching.
This will be _slow_.
You need at least 491MB RAM to run with prefetching enabled.
Phase 2 - using internal log
- zero log...
- scan filesystem freespace and inode maps...

xfs_repair: dinode.c:2136: process_inode_data_fork: Assertion `err == 0' failed.
Aborted
=============================================================
This is xfs_repair 3.1.11, from xfsprogs 3.1.11 from tarball, compiled on
the machine in question, which is a 32-bit OS with 512MB of ram (the
mobo, an old MSI KT6V, pukes if we try to put more ram on it for some
reason). I have run memtest+ on the ram and multiple passes come
back clean as a whistle; the SATA controller is a SiI 3114, which we
had to buy to talk to the 3TB drives; boot is from the VT6420 on the
motherboard and a dedicated 40G Samsung.
I have done some work on this repair booted from a Suse 12.1 rescue disk
with a 3.7 kernel, on the theory that the XFS drivers in the kernel
might help; I found that mounting and unmounting in between multiple
repair runs made me have to do less of them -- though I'm sure more
than two dirty runs before one sees a clean one ought to be Right Out
anyway.
I've seen suggestions on the mailing list archives and other places
that (some) assertion fails were for things fixed in earlier tools
releases, but that one's not helping me...
I have space to move this data off and remake the filesystem,
if I can get it to mount reliably and stay that way long enough.
Any assistance cheerfully appreciated. :-)
Cheers,
