/var/opt/omni directory full

[Lai Nee Shyang_1]

Hi there,

I'm new to omniback and I'm having problem with this directory "/var/opt/omni" because it is nearly full. How can I clear some space?


Thanks

You have two options one is to clear up /var/opt/omni or extend the space in /var or /var/opt/omni depending on whether they are mounted on different file systems.

You can try clearing log files in /var/opt/omni/log .It may not release much space anyway.You can purge the old entries in omniback database using omnidb -purge option.
Then do a readascii and write ascii back to shrink the omnibd size .

If u have enough space I would recommend extending the filesystem.If /var/opt/omni is a directory it would be better to move it to a new file system.
create a new lvol .Mount it in a temp name and cpio the data under /var/opt/omni.

lvcreate -n lomni /dev/vgxx
lvextend -L 200 /dev/vgxx/lomni /dev/dsk/cxtxdx
newfs -F vxfs /dev/vgxx/rlomni
mkdir /tmp/omni
mount /dev/vg02/lvomni /tmp/omni
omnistat
/opt/omni/sbin/omnisv.sh stop
cd /var/opt/omni
find . -depth -print | cpio -pdumV /tmp/omni
mv /var/opt/omni /var/opt/omni.old
mkdir /var/opt/omni
update /etc/fstab
umount /dev/vg02/lvomni
mount /var/opt/omni
/opt/omni/sbin/omnisv.sh start
omnistat
run some query to database

Note :Verify that the file and directory permissions are appropriate.

Try purging the OmniBack database. These files can consume quite a bit of space unless managed regularly.

Try the following. The omnidb get's full rather quickly. You need to do maintance on it about once a month. These are the procedures:

Purging the Omniback database

UNIX
======
1. Calculate the size of the existing Omniback database, by running the
command:
omnidbutil -info
The amount of disk space can be determined by adding up the values in
the 'disk space' column.

2. Create an empty directory on a Mount Point that will accomodate at least
130% of the current size of the omniback database. For this discussion, I
will call this directory , which will include the full path to the
directory, ie, /tmp/omnidb

3. Run the command:
omnidb -strip
This will mark for removal any sessions for which the media has been
reused. When this completes-

4. Run the command:
omnidbutil -purge -detail -days 5
This will remove anything marked by the previous command. This will
remove all filenames for which there are no file versions. This remove any
Aborted Session, and failed Sessions, and Restore Sessions older than 5
days. This command will immediately return you back to the command prompt,
so you will need to periodically check the process list ('ps -ef | grep
omni') until there are no more 'psm' processes running.

5. Run the command:
omnidbutil -writeascii -cdb -mmdb
when this completes-

6. Run the command:
omnidbutil -readascii -cdb -mmdb



Hope this helps,

Brian

Hi there.
Another option cold be to create a directory
on a disk with enough space and create a softlink, that points to this directory.
