Bug#647039: e2fsprogs: e4defrag does not work with LVM device nodes
I wonder if this problem I am seeing is the same one. I am running Ubuntu 12.04 with LUKS encryption and ext4 partitions under LVM. After doing resize2fs -M /dev/xxx; resize2fs /dev/xxx (where xxx is an ext4 partition under LVM), I can get e4defrag consistently to generate a kernel panic/restart. I have attached a kenel traceback, which is preceded by the following messages: Jul 11 07:45:13 blanca kernel: [ 2618.303035] EXT4-fs error (device dm-7): ext4_ext_search_left:1224: inode #20569: comm e4defrag: ix (2276) != EXT_FIRST_INDEX (0) (depth 0)!

Data will be lost I hope this traceback might be helpful to someone.

The chattr +e will migrate older files to use the extent format; it will, however, not defragment the files. This matters primarily for very large files which are tens of megabytes or larger. And if the file system's free space wasn't fragmented, the difference will be marginal even in that case. And if the file system free space is heavily fragmented (say, if you were running it at 80-90% full for long periods of time), e4defrag isn't smart enough to handle this case, so the only real solution to recover the lost performance is to do a backup, reformat, and restore operation. - Ted -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.
