My OS > was RHEL 4.0 ES The reboot in your case was necessary since you were adding the disk to a hardware RAID system which needed to rebuild the raid array. If you have spare disk partitions you can add them to an LVM w/o rebooting, you may have to go into single user mode though. LVM and filesystem resize does not require a reboot. Also, avoid / on a LVM. -- Arun Khan _______________________________________________ ilugd mailinglist -- [email protected] http://frodo.hserus.net/mailman/listinfo/ilugd Archives at: http://news.gmane.org/gmane.user-groups.linux.delhi http://www.mail-archive.com/[email protected]/
