I mounted the root partition at /mnt/test and used du.
server4:/home/ron# du /mnt/test/mnt -hx --max-depth=1
2.7G /mnt/test/mnt/backupserver
0 /mnt/test/mnt/test
2.7G /mnt/test/mnt
server4:/home/ron#
The 2.7GB is the remnant of a first backup attempt to a new backup
server. We backup over NFS, to a server mounted at /mnt/backupserver.
During that backup trial, the new backup server was not configured
correctly, and this machine had not - actually - seen it, though it
had appeared to do so. As a result, this machine tried to do a backup
to that destination, /mnt/backupserver, and had - evidently - filled
the root partition before complaining about space.
I hadn't understood - then - what had happened, and I corrected (only)
the missing NFS export and connectivity. That fix meant that the
mountpoint no longer 'pointed' to a set of directories on the root
partition but - instead - to the NFS export (correctly). A 'proper'
backup then succeeded; what I hadn't realised, until now, was that the
original set of failed-test directories was still there, filling the
partition and, moreover, now invisible.
There are some very clever people on this list; how on earth did
anyone know that.
I need one more piece of advice. I will delete those files but 'I
think' I need to keep
/mnt/test/mnt - because that's the main server fs /mnt directory
/mnt/test/mnt/backupserver - because that's the normal NFS mountpoint
for the backups
and I think I can delete everything within, and beneath,
/mnt/test/mnt/backupserver
Does anyone see a problem with what I intend to do?
regards, Ron
