hi,

After re-reading the mail my comments don't really make sense - please
ignore that mail.

Can you verify if there are still any open file handles on the /mnt/srv
partition that are not accounted for/associated with real filenames ?

Please check with:
"lsof  -nR /mnt/srv"    -- you might want to grep for "deleted"
"fuser -auv /mnt/srv"


Kind regards,
Achim
