greets
I have a customer server that was set up with a hardware raid and on top
of that /dev/sda exists a btrfs filesystem.
Yes, I know, that is stupid (can't change that easily).
In dmesg I get flooding:
[2329426.792480] BTRFS warning (device sda): csum failed ino 7454384 off
81708052480 csum 3746940842 expected csum 3305376500
[2329427.844757] BTRFS warning (device sda): csum failed ino 7454384 off
81708052480 csum 3746940842 expected csum 3305376500
[2329428.929354] BTRFS warning (device sda): csum failed ino 7454384 off

...
I googled how to spot the file containing that problematic block(?):
find / -type f -exec cp {} /dev/null \;
I have that running within tmux now, are there any other ways to find
that file and somehow fix it?
That btrfs contains the root-fs of the server ... so I would maybe have
to driver there, boot from stick or so and btrfsck the unmounted fs?
thanks, Stefan
