increase the fs.

/var if often violaitng, so in the vg00 4gb space is remaining, so planned to increase the /var by another 2gb, more logs are getting generated, so planned to increase the partition size.

I'm guessing you're asking how to do this?

Take a look at the EXAMPLES section of the lvextend man page, in particular the section labeled "Increase the size of a file system existing on a logical volume:".

OK, that was what you were asking.

For your second question, "is it advisable?", you would have to decide. Personally, I would say yes. The other vg00 file systems should not experience much growth and, unless you want to devote a lot of your time to cleaning out /var, it makes sense to utilize your extra space where it is needed.

whether i need to unmount /var before increasing, if so after lvextend i want to use extendfs or fsadm? for increaing /var.

Here's the relevant man page section:

Increase the size of a file system existing on a logical volume:

First, increase the size of the logical volume.

lvextend -L 400 /dev/vg06/lvol3

Unmount the file system.

umount /dev/vg06/lvol3

Extend the file system to occupy the entire (larger) logical volume.

extendfs /dev/vg06/rlvol3

Remount the file system.

mount /dev/vg06/lvol3 /mnt

When I read that, it tells me you have to unmount. Maybe it says something different when you read it.

Fizan,

- Do you have online JFS on the system.
If yes, you dont need to unmount the filesystem.

Check:
# swlist -l product | grep -i OnlineJfs

Following steps needed to extend the FS by another 2GB (2048MB):

1. Check if you have free space & equal free space on both disk:
# vgdisplay -v vg00 | grep -e 'Free PE' -e dsk | grep -v Alt

From above output looks 4.4GB free space available , so you can go ahead:

2. # lvextend -L 6648 /dev/vg00/lvol7 #[4600+2048 = 6648MB the new size will be. ]

3. # fsadm -b 6648M /var

4. # bdf /var #To check.

Cheers,
Raj.

/var its under mirroring whether before increasing the /var mirror has to be breaked.
