I have two mirrored disks. On the mirror I have created a logical volume /dev/VolGroup00/LogVol00 which contains the root filesystem. Initially I made the volume 4GB. Later I needed more space, so I decided to extend the volume to 8GB. I booted from the FC5 rescue CD and ran the following commands: dmraid -a y lvm vgscan lvm vgchange -a y lvm lvextend -L +4G /dev/VolGroup00/LogVol00 fsck /dev/VolGroup00/LogVol00 resize2fs /dev/VolGroup00/LogVol00 So far so good. Then I rebooted the system from disk and got the following error: Checking filesystems /dev/VolGroup00/LogVol00: The filesystem size (according to the superblock) is 2097152 blocks The physical size of the device is 1048576 blocks Either the superblock or the partition table is likely to be corrupt! /dev/VolGroup/LogVol00: UNEXPECTED INCONSISTENCY, run fsck manually. I entered the system administration mode and checked the size of /dev/VolGroup/LogVol00 with "lvm lvs": 4.00G Strange... so I booted with the rescue CD again and checked the size once more from the rescue environment: 8.00G. So it seems that when I boot the system normally it doesn't "see" that the size of the logical volume has changed. Can someone explain this, and hopefully help me fix the problem? /Magnus
