How to increase the ext3 filesystem after lvextend command on RHEL 5.3 64Bit

WW288996 — Tue, 04 May 2010 09:00:33 GMT

Hi All,

I have extended my LV(root filesystem LV) and now I want to increase the root filesystem.

I came to know that I have to use ext2online command to increase the filesystem but I could not able to see that command in my machine.

[root@bhlbmw03 ~]# ext2online
-bash: ext2online: command not found

Is there any other way we can increase the root filesytem after extending LV.

I am using RHEL LVM.

[root@bhlbmw03 ~]# lvdisplay /dev/VolGroup00/LogVol00
--- Logical volume ---
LV Name /dev/VolGroup00/LogVol00
VG Name VolGroup00
LV UUID SoAxkt-ZcDZ-kovq-0NpB-0odg-Y4gx-EYHzex
LV Write Access read/write
LV Status available
# open 1
LV Size 88.12 GB
Current LE 2820
Segments 2
Allocation inherit
Read ahead sectors auto
- currently set to 256
Block device 253:0

[root@bhlbmw03 ~]# df -h /dev/VolGroup00/LogVol00
Filesystem Size Used Avail Use% Mounted on
- 3.9G 84K 3.9G 1% /dev

Found that the following packages are already there in my machine

[root@bhlbmw03 ~]# rpm -qa | grep e2fsprogs
e2fsprogs-libs-1.39-20.el5
e2fsprogs-devel-1.39-20.el5
e2fsprogs-1.39-20.el5
e2fsprogs-libs-1.39-20.el5

What package I have to install to get ext2online utility?

Please help in this regard?

Hi,

Parted can do it. It has a number of GUI frontends: the most popular is Gparted.

Shrink the big partition, making sure the space you free is next to the rot partition, and then increase the size of the root partition.

TAKE BACK-UPS OF EVERYTHING UP FIRST

Check man pages of parted
