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)!
Jul 11 07:45:13 blanca kernel: [ 2618.303059] EXT4-fs (dm-7): delayed
block allocation failed for inode 20569 at logical offset 2276 with max
blocks 1 with error -5
Jul 11 07:45:13 blanca kernel: [ 2618.303069] EXT4-fs (dm-7): This should
not happen!! Data will be lost
I hope this traceback might be helpful to someone.
Thanks,
Geoff
