/var space incress steps

Mast-San — Wed, 03 Aug 2011 08:53:55 GMT

Dear All,

We have HP-UX 11.23 U ia64 server. VAR partition 75% full, what can I do to increase free space? Please guide the same.

Thanks in advance

Thanks & Regards, Mastan.

It may be simpler to find out what's taking all of that space and remove it.

What are the large directories?

For /var/adm/sw/, you can use cleanup(1m) to cleanup superseded patches.

For /var/tmp/, you can remove old files.

For /var/spool/, you can clean up old mail messages.

Hi Mastan:

Analyze output from next commands:

# du -skx /var/* | sort -nr | head -10

# find /var -type f -xdev -size +5000000c -exec ll {} \;

rgs,

Check, with vgdisplay, to see if there is free space in vg00. If there is, you can lvextend the lvol containing /var and then extendfs the file system (see the examples section of man lvextend (1M). If not, you will have to provide extra space through vgextend first or start trimming, as others have suggested.

Hi,

You need free PEs in your root vg (vg00) to be able to extend any LVs. If you dont have any free space, then you need to add new disk and follow below steps.

# ioscan -fnC disk

# insf

# reboot the server in single user mode (i.e. boot -is from EFI shell)

# pvcreate /dev/rdsk/cxtxdx

# vgextend vg00 /dev/rdsk/cxtxdx

# umount /var

# lvextend /dev/vg00/lvol5 (Here, lvol5 is for /var mount point)

# extendfs -F vxfs /dev/vg00/lvol5

# mount /dev/vg00/lvol5 /var (Or use mountall as it is already there in /etc/fstab)

Hope this helps!!!!

Cheers.

Hey;

As others have mentioned, the first thing to do is to see if there is anything that can be cleaned up in /var. That filesystem holds log files and various temp files which have to be periodically cleaned up or the filesystem fills.

Things to check:

* /var/tmp - old files in here

* /var/adm/syslog - logs in here can grow w/o bounds

* /var/adm/*tmp* - btmp, wtmp, and wtmpx grow w/o bounds

* /var/adm/sw/save - where commitable patches are saved.

You should run "cleanup -c 1" to clean up any patches, then check those items above. After that, I tend to run "du -sk * | sort -n -k 1" to find out where the space is being used.

Once you've done that, and still need more space, you can extend the space in /var assuming you have the space available.

First, find out if you have online jfs: "swlist -l fileset | grep -i onlinejfs".

Next, find out if you have the space in vg00 to extend: "vgdisplay vg00"

If you have the space, ID the lv for /var: mount | grep -i "/var " | awk '{print $3}'

extend the filesystem: lvextend -L ${new_size_in_megs} ${lv}

if you have online jfs: fsadm -F vxfs -b $(new_size_in_megs}m /var
If you don't have online jfs, unmount /var and run extendfs -F vxfs ${raw_lv}

You'll probably have to go into single user mode in order to unmount /var. *LOTS* of processes keep files open in that filesystem...

Hope that helps.

Is that supposed to be a question or a statement? If it's a question, what is it you're questioning? If it's a statement, could you explain what you're commenting about?

Actually triplicate.

Duplicate, triplicate - whatever. Frankly, this sad excuse for a Community can use all the traffic it can get.
