Hi Brian,
I'll start from the beginning.. I have a mdadm raid 5 array with 4 SATA
disks (2xST4000NC000 and 2xST2000NC000) that were attached to a
RocketRaid 2722 controller in an Addonics tower all on the same PMP.
Something had a fit in there and knocked the RR driver offline taking
out the array when I was adding data to the array.
I moved the disks off the array onto individual sata controllers on the
system and finished my repairs from there as that setup has some kind of
issue when I near 89% usage on the array.
I ended up with the xfs log and superblock being screwed up. I was
running kernel 3.19.18 and upgraded to 4.6.7 in case there was some
unknown bug hiding in there. I did all my repair work on 4.6.7 kernel.
I could not get the 4.5 tools to sort things out as the log was messed
up (the log head/tail could not be found), and the superblock was messed
up (if I remember right it was a metadata error).
I tried moving the log to an external setup, but xfs_db would complain
about corruption at 0x0/0x200 in the superblock and not let me do this.
I upgraded to 4.10 tools with hope but no luck any which way. For some
reason with 4.5 I could use the xfsrepair -L option and then re-run with
xfsrepair and no -L option and it would do something with the log and
superblock and I could mount the FS again. Doing that with 4.10 would
not work at all.
I ended up downgrading to 4.5 tools again and doing the xfsrepair,
xfsrepair -L and xfsrepair and I had success. I have no idea why, but it
worked and everything is happy again. I'm on kernel 4.8.17 at the moment
and so far so good with the drives nowhere near the highpoint card.
I've attached a printout of the superblock that was messed and as it is
now as well as one of the xfsrepair straces. For whatever reason, when I
went to pull the sb values for this e-mail I had 4.10 installed again
from a system update and it kept segfalting.. going back to 4.5 worked.
If you need more I can dig through syslog and messages and see what I
can pull out for you.

Hello,
I went through a corruption issue on a v5 filesystem I have and the v4.5 of
the tools fixed the log but 4.10 would only complain about not being able to
fix it?
Can you provide details please?
Brian
I can provide some background on the issue if that helps but I though it
might be worthwhile to mention the above..?
