error 2001, no inode item

[Arun Persaud <apersaud@lbl.gov>]

Hello

my HD recently started crashing, so I rescued all files to a new one and
thought that this might be a good time to convert from ext4 to btrfs. I
copied all the files from my old HD using dd, converted and then resized
the file system. However, my old drive already had some errors.
Currently I have one file that I can't rm or overwrite (stale file
handle). Here is what I get when running btrfs check:

> btrfs check /dev/sda4

the file is a git object, so that's why the name looks like a hash ;)

I'm running opensuse/Tumbleweed.

Any idea how I can fix the above? check --repair doesn't seem to help.
Any suggestions would be highly appreciated.

thanks
