Description Zing 2009-06-22 20:42:57 UTC
Description of problem:
I was fooling around with mounting by UUID in my fstab and noticed that tools like mount and df started returning dm-* device names, where I expected /dev/mapper names.

... I tried two patches (the tip @ 46f3eeca59) and that looked like it fixed it on my end (admittedly a quick test though).


Version-Release number of selected component (if applicable):
e2fsprogs-1.41.4-10.fc11

How reproducible:
fairly easily

Steps to Reproduce:
1. have a lv available or one that exists (i.e. /usr, /tmp, etc.)
2. in /etc/fstab switch to mount it by "UUID=<uuid num>"
3. reboot
4. $ blkid -l -t UUID=<uuid num>

Actual results:
/dev/dm-?: UUID=<uuid num>

Expected results:
/dev/mapper/myvg-usrlv: UUID=<uuid num>

Comment 1 Eric Sandeen 2009-06-24 17:39:43 UTC
This upstream patch should fix it:

http://git.kernel.org/?p=fs/ext2/e2fsprogs.git;a=commitdiff_plain;h=4271e23942bdc60e1fa6c0b26bc666a94a8b3e1d

and I'm currently building it into F10 and F11 to fix bug #497259

It should be in updates-testing shortly.

Thanks,
-Eric
