cd /etc/opt/resmon/log
ls
api.log api.log.old client.log client.log.old emsagent.log registrar.log reslog.html reslog.old.html


Is it possible to move the old log files to other file system (or by soft link)..like

(a)api.log.old (b) client.log.old (c) reslog.old.html

(4) OR is there are any other solution or i can move to get more free space on root (/).

Thanks in advance.

Re: How to make more free space on root LV

Hi


1)Check for the NSR logs at /nsr , ask the application team if they can be moved to some other filesystems or can be kept at other location. That consumes a lot of space.

2) Ignite is the most Safe and Reliabale way of doing the Root LV increase.

3)In the unconvential ways if possiblr and having free space in the VG, the pvmove for the lvol4 can be tried if that is not defined as a Contiguous Volume, generally that use to be /tmp.

Re: How to make more free space on root LV

I would suggest that you move /nsr elsewhere. I'm not sure what it is, but I don't think it NEEDS to be part of the root VG.

If you have some spare space you can create another VG/FS and move /nsr to it, giving you plenty of space in /.

Shalom,

You have data in /etc, not only configuration files.

Clean it up.

Re: How to make more free space on root LV

Hi once again....

(1)Is it possible to move the old log from

#cd /etc/opt/resmon/log

# ls -ltr
total 6496
-rw-r--r-- 1 root root 500141 Aug 29 2007 client.log.old
-rw-r--r-- 1 root root 1000093 Nov 10 2007 reslog.old.html
-rw-r--r-- 1 root root 500673 Dec 17 2007 api.log.old
-rw-r--r-- 1 root root 213126 May 25 2008 client.log
-rw-r--r-- 1 root sys 13612 May 25 2008 emsagent.log
-rw-r--r-- 1 root root 208667 May 25 2008 registrar.log
-rw-r--r-- 1 root root 67916 Oct 9 15:43 api.log
-rw-r--r-- 1 root root 765213 Jan 27 08:02 reslog.html

old log ..i.e

(a)api.log.old (b) client.log.old (c) reslog.old.html

(2)/nsr taking more space but i am not sure which one can we move without affecting Env.

Re: How to make more free space on root LV

Hi Subodh,

You have your back-up client software (Networker) installed in the root filesystem.

Reinstall or move it to a separate filesystem, this will save 180MB in your root filesystem.

Re: How to make more free space on root LV

Hello Subodh,

can find from googl emore about /nsr/applogs .
These seem to be the logs for Oracle RMAN Backup.

Immmediately get in touch with the Oracle Database team or the backup team and ask about utility of these log files.


You can well leave the resmon logs that is the Event manager logs. They are taking only 9 MB of space.

Where as /nsr seems to take close to 184 MB.


This is always a good practice while working in the Production Environment to at least have a backup of any file that you are going to delete.


As suggested by the Gurus before deleting a file you can have the File copied to some other location or can have a zip of that file on other location or moiunt point .

Sujit

(2)/nsr taking more space but i am not sure which one can we move without affecting Env.
---
as long as you backup is not running.

Create a new filesystem
Stop your legato client (/sbin/init.d/networker stop)
Move your /nsr directory to a nsr_temp
Create /nsr
mount your new filesystem on /nsr
check the permissions on /nsr
Copy the data from nsr_temp back to /nsr and start your networker client.

Re: How to make more free space on root LV


assuming / is /dev/vg00/lvol3


pvmove -n /dev/vg00/lvol4 to another disk
lvextend -L XXXX /dev/vg00/lvol3
fsadm -F vxfs -b xxxxxx /

you can then pvmove lvol4 back to the original disk.

Re: How to make more free space on root LV

/etc/nsr must never be installed in the root filesystem. In the / filesystem, /etc and /sbin should be the largest directories, nothing else. If removing and corectly installing NSR is not an option, shutdown NSR, then move everything in /nsr to /var. Finally, create a symlnk from /nsr to /var/nsr.

Note that the resmon directories are too small to worry about (9 MB). NSR is 184 MB - fix that one.

Re: How to make more free space on root LV

Hi...

Further update on this...

I'd moved a /nsr/applogs to newly created file system and made a soft link between them.

my root is now 67% ...

Thanks to all for helping me in this scenario.
