Question How do I extend an ext3 partition?


I have a SAN LUN of 100 GB created as an ext3 partition of the entire lun and need to make the lun and partition larger. The SAN LUN was grown to 200 GB and the system sees the new size however the file system still sees the partition as 100 GB. How can I expand the partition to include the entire lun again without rebooting the system? I can unmount the partition but the system can not reboot.

I'm not familiar with that but, on my FC4 box....

For example: /dev/hdb2

umount the partition

fsck it : e2fsck -f /dev/hdb2

resize the filesystem : resize2fs -f /dev/hdb2

RHEL4 supports ext2/ext3 online resize, guess this is something you need:
