Thread: Can't run fsck on root partition

-

i'm running ubuntu 10.04 lts , yesterday machine started booting root partition marked read only. booted 10.04 lts install dvd , tried run fsck on /dev/sdb1, keep getting result:
code:
ubuntu@ubuntu:~$ sudo fsck -yv /dev/sdb1 fsck util-linux-ng 2.17.2 e2fsck 1.41.11 (14-mar-2010) fsck.ext4: device or resource busy while trying open /dev/sdb1 filesystem mounted or opened exclusively program? ubuntu@ubuntu:~$
the unusual event that's occurred working on rsynch script last friday, kept hanging , needing killed. wouldn't expect have caused level of problem, though.

ran gparted, reported couldn't find valid filesystem superblock /dev/sdb1.

here's fdisk output in case it's helpful:
code:
ubuntu@ubuntu:~$ sudo fdisk -l  warning: gpt (guid partition table) detected on '/dev/sda'! util fdisk doesn't support gpt. use gnu parted.   disk /dev/sda: 160.0 gb, 160000000000 bytes 256 heads, 63 sectors/track, 19376 cylinders units = cylinders of 16128 * 512 = 8257536 bytes sector size (logical/physical): 512 bytes / 512 bytes i/o size (minimum/optimal): 512 bytes / 512 bytes disk identifier: 0x00000000     device boot      start         end      blocks   id  system /dev/sda1   *           1       19377   156249999+  ee  gpt  disk /dev/sdb: 1000.2 gb, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders units = cylinders of 16065 * 512 = 8225280 bytes sector size (logical/physical): 512 bytes / 512 bytes i/o size (minimum/optimal): 512 bytes / 512 bytes disk identifier: 0x000e1cf8     device boot      start         end      blocks   id  system /dev/sdb1               1      120853   970751691   83  linux /dev/sdb2          120854      121601     6008310    5  extended /dev/sdb5          120854      121601     6008278+  82  linux swap / solaris ubuntu@ubuntu:~$
