Resize ext3 filesystem in RHEL AS 4.0

Gulam Mohiuddin — Wed, 29 Aug 2007 09:26:57 GMT

I would like to increase logical Volume "LogVol07" and filesystem "/u07" by 2GB on Red Hat Ent Linux AS 4.0.

/u07 mounted on /dev/VolGroup01/LogVol07

Do I need to unmount the filesystem first?

I guess RHEL 4.0 uses LVM2

Thanks,

Gulam.

You can extend a logical volume while it's in use, and you should be able to use ext2online to expand the filesystem while it's mounted. There are some limitations and warnings, you should review the man page carefully and make sure you're comfortable with it.

The LV expansion with lvextend can be done online.

The file system expansion, you can do it online if you have ext2online, available for RHEL4 in the e2fsprogs package.

e2fsadm -L 56G /dev/vg01/lvol9

work in single step(e2fsadm takes care of extend too;man e2fsadm)

you can do the onine extend if you have ext2online(whereis ext2online)
