Hi everyone,
Few days ago, during a system update, some errors appeard:
"can''t
create file XXX (Input/Output errors)". ls, stat, rm, on these files
gave always the same Input/output error. "btrfsck --repair" told me
that
some leaves were corrupt (bad key order) but nothing changed. They were
all in the same folder so i tried to move its contents into another dir
and delete it.
Surprisingly it fixed some bad files but i got new errors. Trying to
delete the file "kgthemeselector.h" gives these kernel messages:

I''m on a 64 bit Arch Linux up to date, uname gives
Linux ... 3.6.11-1-ARCH #1 SMP PREEMPT ... x86_64 GNU/Linux
Is there a way to get rid of these files?
Thanks!
