Seaf-fsck.sh crashes with error

Seafile Server
1

Hi,
I’m getting errors when accessing data from a library:

https://seafile.example.com/seafhttp/files/c2dd59fe-05b7-4fd0-8259-194d3ece519b/ABBYY_FineReader_14.exe

Which gives me:

Secure Connection Failed

An error occurred during a connection to seafile.example.com.

so the Library seems corrupted. I tried to fix it with seaf-fsck.sh:

seafile@seafile:~/seafile-server-latest$ ./seaf-fsck.sh 4ad6f367-a0d4-4f75-8b7f-65df3bdac157

Starting seaf-fsck, please wait ...

seaf-fsck run done

Done.

Which give me a segmentation fault:

This is a very old Library and I will need to repair it. Deleting and rebuilding it will be a real pita.
The Server runs Debian 10 (buster) and seafile is the CE Edition 9.0.8.
Thanks for help!

Ok, so it was fixed in 9.0.9.
seaf-fsck.sh does not crash anymore but the fix was kinda disappointing. It simply deleted every file in every corrupted directory. As for the corruption, they occurred during the first versions with the golang server which crashed badly a few time during an upload to this specific library (well, the library is called software and so there are a few multi-gig-sized iso files I wanted to save :slight_smile: ). So for me I restored that library from my last backup via seaf-fsck.sh export and uploaded it again. Yes, a real pita. But back in business.
