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"
