I posted the following to the ext2 help forum and got the included response; By: jpolache ( Jon Polacheck ) reasize2fs fails 2002-11-13 13:23 I have an lvm volume for my /usr filesystem on a Mandrake 8.1 server. I did a lvextend, and am now trying to resize the filesystem into the logical volume. I went to runlevel 1, unmounted all my filesystems (umount -a) and ran e2fsck on /dev/sys/usr. I got output indicating that the superblock size was 793600 blocks and the "physical" size was 665600 blocks. e2fsck ended with the following; Error scanning inodes (336000): can't read next inode /dev/sys/usr: 13494/400000 files (1.2% non-contiguous), 578502/793600 blocks When I then run resize2fs, I get the following output; resize2fs: Can't read a block bitmap while trying to resize /dev/sys/usr. The file system on /dev/sys/usr is now 665600 blocks long. Any suggestions? By: tytso ( Theodore Ts'o ) RE: reasize2fs fails 2002-11-14 07:28 That's an LVM problem. e2fsck was very clear when it told you that device was smaller than the size specified in the superblock. ...there was probably severe damage to the filesystem which was done, because resize2fs attempted to shrink the filesystem down to 665600 from the superblock size of 793600. But since LVM had apparently already gotten the idea that the device was now smaller, any data that was stored in the blocks between 665600 and 793600 has been lost. ...................................................................................... Any suggestions as to how I can proceed from here? _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
