File System in a VG

[Ricky B. Nino]

Hi,

I have a file system in my vg03 that is about to get full.

I have a free disc available.

How can I use this free disc for the same file system?

regards...

[Balaji N]

add this disk to the vg.

1. pvcreate /dev/rdsk/xxxxxx
2. vgextend /dev/vg03 /dev/dsk/xxxx
3. lvextend /dev/vg03/lvol_to_be_extended.
4. umount the lvol
5. extendfs /dev/vg03/lvol.....

hi,

before adding the disk check whether the parametere Max PE per PV and PE size.
this will determine what is the maximum size of the hard disk
that VG will support.
suppose Max PE per PV is 2500
and PE size is 4 ( default is 4 this can be also changed using vgcreate command).
then multiply both , Max size of the PV can be only 10GB.

if ur VG supports u can follow the above steps.

If you got Online JFS, there is no need to unmount the filesystem, you can extend it online.

There are always ifs.

Of the fs was set up continguous strict, you can't extend it unless its ajacent to the free space.

You can check it with

vgdisplay -v /dev/vg03 | more

If it was set up strict contiguous, you'll need to back it up remove it and put it back in according to the above instructions bigger and then restore the data.

Good Luck.

Hi,

normally lvol1 and lvol2 under vg00 are contiguous and other lvol's under vg00 and other vg's are all vxfs or jfs
(fstyp /dev/vgxx/lvolx)

In your case insert the free disk to the system and after conforming that system is recognizing the disk drive (ioscan -fnC disk)
#pvcreate -f /dev/rdsk/cxtxdx
(cxtxdx is the free disk)
#vgextend /dev/vg03 /dev/dsk/cxtxdx

Now you can create any new lvol's or can extend the existing lvol's under vg03
(lvcreate, lvextend)
