As /usr/src/linux/Documentation/devices.txt says:
58 char Hayes ESP serial card - alternate devices
0 = /dev/cup0 Callout device for ttyP0
1 = /dev/cup1 Callout device for ttyP1
...
block Reserved for logical volume manager
109 char Reserved for logical volume manager
That is, LVM has block major number 58 reserved for its own use, as well
as char major number 109. One of my machines has LVM installed, with a VG
called Grupo00 and two LV, "mp3" and "usr" (ls -l /dev/Grupo00):
total 0
crw-r----- 1 root disk 109, 0 jun 4 12:33 group
brw-rw---- 1 root disk 58, 0 jun 5 04:48 mp3
brw-rw---- 1 root disk 58, 1 jun 4 17:50 usr
Hope it helps. Regards,
