Marco, I've used this process with ext3 file systems when we need to extend a partition (usually on a SAN drive or a VM server where you add additional space via the host) Note, this process ONLY works on the last partition of a drive, if it's not the last one, don't do this! I have successfully resized a couple ext3 root partitions with this process: 1. boot into single user (or if it's the root partition you're working with, boot off your RHEL install CD into rescue shell - don't mount the partition) 2. use fdisk to delete the last partition on the drive in question 3. create a new partition - use all available space - hopefully fdisk will have additional space for you to use, if not quit without writing. 4. exit/write in fdisk (don't do this between steps 2 and 3 or you're hosed!) 5. run resize2fs /dev/sdXX (whatever dev corresponds to your new partition) 6. resize2fs will ask you to run fsck - so do what it wants. 7. re-run the resize2fs command (this can take a while depending on size, # of files) 8. test mount the partition to verify the size and existence of files. 9. reboot and have a beer. Of course you'll wanna do this on a test system first to verify it works for you and also take a backup of the partition in question first. :) Good luck, Josh _______________________________________________ rhelv5-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/rhelv5-list
