/dev/dm details...

[trax]

Hello,

Simple question about right on device

root on SERVER # ll /dev /dm*
brw-r----- 1 root disk 253, 0 Dec 12 11:25 /dev/dm-0
brw-r----- 1 root disk 253, 1 Dec 12 11:25 /dev/dm-1
brw-rw---- 1 root root 253, 10 Dec 12 11:25 /dev/dm-2
brw-rw---- 1 root root 253, 11 Dec 12 11:25 /dev/dm-3
brw-rw---- 1 root root 253, 12 Dec 12 11:25 /dev/dm-4
brw-rw---- 1 root root 253, 13 Dec 12 11:25 /dev/dm-5

root root is for device and root disk for partition ?

Someone has commented values on /etc/udev/rules.d and on next reboot new DM appears...


Dm name are not fixed, no?
Is it possible to fix name of dm? how?

Thanks,
