Hi: I have an NFS volume that I'm trying to resize a partition on. Something about the fdisk process is corrupting something on the drive Before running fdisk, I can mount the volume find: $ mount /dev/sdo1 /home ... and the volume is mounted fine. And, $ e2fsck -f /dev/sdo1 /dev/sdo1: clean, ... But then I run fdisk to rewrite the partition table of this drive, to expand the /dev/sdo1 partition w/o losing data: $ fdisk /dev/sdo # Type 'd' to delete the primary partition # Type 'n' for new partition # Type 'p' for primary # Type '1' for 1st # Type Enter for 1st cylinder # Type Enter for last cylinder (full disk) # Type 'w' to finish Calling ioctl() ... Syncing disks ... But then something has gone wrong. $ e2fsck -f /dev/sdo1 e2fsck 1.39 (29-May-2006) Couldn't find ext2 superblock, trying backup blocks... e2fsck: Bad magic number in super-block while trying to open /dev/sdm1 ... And I can't mount the volume any more: $ mount /dev/sdo1 /home mount: you must specify the filesystem type What am I doing wrong? Am I missing a step of the process? Thanks!
