Title:
old e2fsprogs version can corrupt fs during offline resize
Status in e2fsprogs package in Ubuntu:
Confirmed
Bug description:
The version of e2fsprogs (1.42.5 and below) included in Precise,
Quantal, and Raring contains the bug described here:
http://forums.whirlpool.net.au/archive/2060328
and fixed in 1.42.8. 1.42.8 is included in Saucy. I think the newer
version should be included as an update, as the bug causes data loss.
Further, documentation should reflect that it isn't necessarily better
to unmount before resizing under ext4 - at the moment, it is always
impressed on everyone to NEVER touch a filesystem online.
I believe Ubuntu's installer sets the flag (resize_inode) in question
by default, so the combination of:
1) ext4 with resize_inode set
2) gparted and documentation insist that you only ever modify the filesystem
offline
3) the old version of e2fsprogs
creates the risk that the holes in the swiss cheese line up and lead
to a disaster.
