Hi Karl,
thanks for the prompt answer.
FYI: I always use the "-x" flag on du too, as this will not recurse down
other mounted file systems - e.g. if you have /var/cache on a separate
logical volume.
that's good to know. This doesn't change anything in this case, though :
server:~# du -h -s -x /var
1.6G /var
- Deleted files which are open: When a file is deleted, the space is
usually freed immediately. UNLESS the file is open, in which case
the space will not be freed until whatever-has-it-open closes it.
good point ! I'll check with the sysadmin whether he can reboot
the server or not
- Other mountpoints: If you have lots of files in a subdirectory
(e.g. /var/cache) and then mount another file system on /var/cache,
you cannot reach the original contents of /var/cache - and this will
then be invisible to "du"...
I don't think this is the case here, but that's something I'll try to
keep in mind too :
server:~# mount | grep /var
/dev/mapper/vg00-var on /var type ext3 (rw)
rpc_pipefs on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
in your case:
lvdisplay vg00/var
as you have a logical volume mounted on /var.
Hope this helps
yes it does, thanks again. Hopefully a reboot is all we need ..
David.
