The file may have been unlinked (name to inode mapping removed from the filesystem), but the inode and therefore the data will stay until no process references the inode. I *think* this may be what's happening in your case?

Hi,

i have a strange situation:
A domain is still running where domblklist points to a snapshot file and also dumpxml says the current drive is that snapshot file.
But the file has been deleted hours ago. And the domain is still running. I can login via ssh, the database and the webserver are still running,
domain is performant.
How can that be ?
Also lsof shows that the file is deleted:
