Smile Resizing the LVM

Hi All,

I have Volume Group contains 5 logical volumes...I need to increase one of the logical volume with 5G and volume group has sufficent space to increase it..........

I think these are two commands to do that.


Nothing is I went to my friend GOOGLE.......

After googling, It mentioned that online resize support only exists for ext3 and not ext2.

then i found all other 4 logical volumes are ext3 filesystems & the one i m trying to increase is ext2 filesystem.So i tired to convert the the ext2 to ext3 fs.

I thought this is simple.....

tune2fs -j
edit /etc/fstab [replace ext2 wiht ext3]
mount -o remount

And this didnt work at all..........

Please suggest me is there any way to increase the filesystem wihtout bring unmounting the FS....

Any help is appreciated...

Its remain with ext2 yet and I am not able to convert it.

If you have RHEL, you should use the Redhat LVM Admin guide.
There is also a LVM guide on
