Question

df -h output confusing ?

Asked by: rajsolaris

Ok. We had one  of the server out side of our office network which will talk to the peoplesoft DB and  which in turn would talk to our application server  and the application server to our internal Oracle DB the application server is a local zone so I had to make a ruleset to allow the 1521 port to aloow backtrace i.e. there were random ports involved in this. so something like this

 pass in quick proto tcp from <ip address> port=1521 to any port > 1024 group 188

that solved the issue and the ETL load was completed without any hassle.
Thanks,
-Raj

You should run the du command again, but run it like this:

du -sdh *

I don't know what to tell you. It may be that there is an invisible file (unlinked) on the root filesystem somewhere in which case rebooting should reclaim the storage. It may also be that there is a large file in a directory that is shadowed by a filesystem being mounted on it. And the usage may be an artifact of VxFS, with which i have very little experience. Sorry.

That is ok. Thank you. I will try to find out by installing lsof, that which process files are open in case
and will try to go ahead.

 

by: SaranyakkaliPosted on 2009-11-28 at 01:37:46ID: 25924610

Try this

fuser -cu /fs name
cd /fsname

du -sh * |sort -nr

if it show the correct o/p it's okay other wise run the below command

fuser -ck /fsname

it will kill all the sessions and use the below command

mount -F vxfs  -o remount /fsname

 

by: mectzaPosted on 2009-12-02 at 21:27:55ID: 25959441

You don't by any chance have any old snapshots lying around do you?  Try:
zfs list -t snapshot

If so, removing them (zfs destroy snapshotname) should sort out your problem.
