Fixing file system corruption on Synology NAS

I recently recycled my hard-drives on my Synology DS1010+ as one of the drives started to fail. Migration of the drives was easy, but I did notice that I had file-system corruption when looking at dmesg:

htree_dirblock_to_tree: bad entry in directory
Multiply-claimed block(s) in inode

The Synology does not have a facility to check the file-system during boot up, and the following instructions will allow you to run a file-system repair (if possible, make a backup of critical files before):

1. Make sure that you have SSH enabled and log into the Synology via SSH
2. Shutdown all services except SSH (this will unmount the volume):

   syno_poweroff_task -d

3. Enable the volume:

   vgchange -ay

4. Check for errors, but do not fix:

   e2fsck -nvf -C 0 /dev/vg1/lv

5. Try to fix the file-system errors

   e2fsck -pvf -C 0 /dev/vg1/lv

6. If -pvf can’t work, use -yvf instead.

   e2fsck -yvf -C 0 /dev/vg1/lv

7. Reboot the Synology
