Description Alexander Skwar 2007-08-31 09:35:56 UTC
I upgraded to sys-fs/device-mapper-1.02.22 from 1.02.19-r1. When I now run df, I get something like this:

askwar@hetzner ~ $ df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/hda5               484602    315987    163611  66% /
udev                     10240       136     10104   2% /dev
devshm                  253956         0    253956   0% /dev/shm
/dev/dm-1              2844672   1794948   1049724  64% /usr
/dev/dm-4              1048540    195464    853076  19% /tmp

Note the "/dev/dm-1" and "dm-4". This used to look something like this:

--($:~)-- df
Dateisystem          1K-Blöcke   Benutzt Verfügbar Ben% Eingehängt auf
/dev/sda6               489992    287403    177289  62% /
udev                     10240       168     10072   2% /dev
/dev/mapper/sys-Gentoo
                       4521840   2950912   1570928  66% /Gentoo
/dev/mapper/sys-Home   3192584   2748392    444192  87% /home

The new output (with /dev/dm-*) is pretty much useless, as it hides the information on what volumegroup and logical volume the filesystem is located. "I" suppose it's because of a change in 64-device-mapper.rules? 

As it is now, the files in /dev/mapper are now symlinks to /dev/dm-*. It used to be so, that the files in /dev/mapper where the real block device files.
