Disk Usage 100%

orclrunnerDec 9 2014 — edited Dec 10 2014

OEL 5.10

Oracle 11gR2

Database has been up and running for a month, without incidence.

But yesterday, I could not log in to Oracle though sqlplus. I got unable to write I/O error for audit_file_dest.

I knew it was not privileges issues so I checked the disk space

[root@dub-ImrORA2 ~]# df -h

Filesystem Size Used Avail Use% Mounted on

/dev/mapper/VolGroup00-LogVol00

419G 398G 0 100% /

Not sure where the missing 21G is, maybe the swapfile.

I used Linux "find" command to locate large files and there was nothing that would cause usage to be 398G.

I rebooted the server...it took a while to come back up, but when it did I re-ran the "df" command

[root@dub-ImrORA2 ~]$ df -h

Filesystem Size Used Avail Use% Mounted on

/dev/mapper/VolGroup00-LogVol00

419G 16G 382G 4% /

Now this is what I was expecting.

Any ideas what would cause disk usage to jump to 100%?
