Reg:increasing file system space

[praneepteja]

Can any one give correct commands in a order to increase space of filesystem which are built in LVM.Please try give me whole procedure.

The commands are lvextend and extendfs. Take a look at the man page for lvextend. In the EXAMPLES section, the procedure is clearly explained.

Hi,

if you have online jfs license you can extend fs online

swlist -l product | grep -i online

Procedure:

lvextend -L 1500 /dev/vg00/lvolxx (1500 as MB)

if you don't have licence

umount /mount_point
extendfs /dev/vg00/lvolxx
mount /mount_point

if you have:

fsadm -F vxfs -b 1536000 /mount_point (1500*1024)

Hi,

Please first provide following:
OS version?
Is an OS filesystem related?
Have you installed OnlineJFS?

Rgds.

OS version is hp-ux 11i v3

It is not OS related file system

I have vxfs in my rx 8640 integrity server

Hi,

You can follow kenan's procedure and make use of the fsadm command rather than extendfs... Seems like you have an environment better than base or foundation. Note with fsadm you mention the mount point and_not the device file of the logical volume.

Remember, the lvextend command gives the complete size unlike certain other flavors of unix. With the -L option, you need to specify the "complete" size and not just the size you_want_extended.

Do assign points for those who help you out.

Extend the logical volume.# lvextend -L 144 /dev/vg01/lvol9
For systems with OnlineJFS: # fsadm -b 147456 /test1

if u don't have online jfs u have to umount /test1
then use extendfs command.

thanks and regards

first u have to check space is available in vg
by using vgdisplay

then free PE*PE size(MB)

then lvextend -L 574440 /dev/vgtest/lvol9
then fsadm -b 574440m /test1(where test1 is mount point) if u have online jfs then only
u can do it
otherwise u have to umount the file system first. then increase the logical volume then increase the file system by using extendfs command.
