Public bug reported:
Binary package hint: linux-source-2.6.17
hi,
I have the following setup:
Ubuntu edgy (server) amd64, kernel 2.6.17-10-generic all patched-up-to-
date
3 disks of 500Gb each, a raid 1 over the first 200 megabytes for /boot and a
raid5 over the rest.
The rest is a LVM vg which houses all my partitions.
>From time to time I resize one partition or the other, and up until now
that always worked like a charm, until a little while ago I suddenly
couldn't resize my /home partition to 100Gb. dmesg showed:
[1097453.120232] EXT3-fs warning (device dm-3): ext3_group_add: No
reserved GDT blocks, can't resize
and later:
[1103585.148261] EXT3-fs warning (device dm-3): ext3_unlink: Deleting
nonexistent file (4378758), 0
Well, I figured that I had to unmount it at last, so I did a fuser -km
/home while logged in as root and unmounted the /home filesystem.
This is when the shit hit the fan :)
