This seems to me as a bug from upstream that is filtering down through the distro's.
Using Ubuntu 10.10 LiveCD's e2fsck from the e2fsprogs package 1,41,12 failed to check an ext4 disk with errors saying the aforementioned error. Using a systemrescuecd-x86-2.1.0 CD's e2fsck from the e2fsprogs package 1.41.14 failed to check an ext4 disk with errors saying the aforementioned error. Using a Slax 6.1.2 CD's e2fsck from the e2fsprogs package 1.41.3 (2008) checked and fixed an ext4 disk with errors. Even though the Slax CD could not mount or do anything with the partition as it does not have ext4 support. Go figure. This leads me to think that this has not been fixed E2fsprogs 1.41.13 (December 13, 2010) states: "Fixed a bug in e2fsck where if both the original and backup superblock are invalid in some way, e2fsck will fail going back to the original superblock because it didn't close the backup superblock first, and the exclusive open prevented the file system from being reopened." Unless Gentoo's e2fsprogs 1.41.14 missed this patch?? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/711799 Title: e2fsprogs wrongly identifies ext4 as mounted -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
