CentOS 6.2. I have a 2TB drive, one partition, which is used for online backups. It filled up the other day. I moved a couple of b/u directories off it, and deleted the originals, which should have given me 42G free. I also reduced the reserved blocks by 1/3rd.
I've just finished an fsck, which it needed anyway, and in which there was a problem in an HTREE directory node.
df *still* tells me that there are zero bytes free.
Clues?
