Seafile library damaged

Hi, I’ve got a similar problem as described here that I can not access a certain shared library, while others are working fine. The library is damaged after a recent server crash.

seaf-fsck.sh output:

/opt/seafile/seafile-server-latest/seaf-fsck.sh --repair 83a08e46-cd97-4553-aaae-223dd7e46c0c

Starting seaf-fsck, please wait ...

I also tried to run seaf-gc.sh, but it doesn’t want to look at the library because of the dmaaged HEAD commit. Any way to repair the library?
