Re: lvextend
To extend File system first you need to check for free PE in VG, if you have free PE in VG than you can extend it.If you have online JFS installed no need to unmount
lvextend -L 6000 /dev/vgname/lvname
than fsadm
For renaming
you need to create directory called /backup1
copu all data from /backup to /backup1
umount /backup
edit /etc/fstab change /backup to /backup1
mount -a

Re: lvextend
fsadm -F vxfs -b 6000M /backup
if not
umount /backup
extendfs -F vxfs /dev/vg01/rlvol3 # adjust vg and lv names acc. to your system
The fastest way to rename it from /backup to /backup1 goes through taking the mountpoint offline:
mkdir /backup1
umount /backup
mount /dev/vg01/lvol3 /backup1 # change vg and lv according to yours
at this point, don't forget to modify /etc/fstab, if this is a filesystem to be mounted at the boot time.
Hope this helps

Re: lvextend
why we need to copy all the data from /backup to /backup1 for changing the mount point.

Re: lvextend
How you will get in new mount point without copying the data ?
Simply mounting with it on new mount point you will not get data :-)

Re: lvextend
You meant say that data is residing on mount point instead of file system??????

Re: lvextend
My Mistake, I read question wrongly
you are correct, I thought we have created new LV as well and than mounting it on another mount point :-)

Re: lvextend
I don├в t wanted to check..there is no need of copy file system for changing mount point.
just unmount file system and mount it on new mount. All the data will be available under new mount point
