I have here a 2TB Verbatim USB2 HDD, partitioned with LVM and
containing a single logical volume with a BTRFS filesystem.
When I read from the filesystem everything is working fine, I can
access all the files. I can "btrfs scrub" the whole drive without any
errors and "btrfs check" can't find anything either.
However when I try to write anything beyond a few KB onto the drive or
try a "btrfs balance" or "btrfs fi resize", the write gets extremely
slow (<100KB/s) or things just freeze. dmesg is getting filled with
call traces from btrfs and a call to "sync" will take 5-10 minutes to
complete, if it completes at all.
I did a non-destrictive read/write scan of the drive with:
badblocks -nvs /dev/vg_verbatim2tb/btrfs
And that worked fine as well, so it seems like the btrfs on there
corrupted in some way that "btrfs check" can't detect.
