Description Corey Marthaler 2006-09-01 21:45:22 UTC 
Description of problem:

Major number gets ignored.

[root@link-08 ~]# lvcreate -L 20M -n major -My --major 222 --minor 111 gfs
  Logical volume "major" created

gfs-major        253 111 L--w    0    1      0
LVM-mlBLc3EbXgmSRUU8IZ5zLN143vKWfAqnFRsxOIpbkMYmzTLtneCEyrlbVwZznXMU

*** If this does get fixed, then the major number option needs to be added to
the man page. ***

This is open for years...

In kernel 2.6 specifying major number lost its importance with dynamic major allocated.

Can we deprecate this option in lvm2 upstream? I think it is now worth it to support it in kernel anymore.
Comment 6 Zdenek Kabelac 2013-05-14 11:10:08 UTC 
I believe we just need to document this behavior and close this bug as CANTFIX.

Comment 9 Peter Rajnoha 2014-01-30 10:39:14 UTC 
OK, we can just document this a bit more.
Comment 10 Peter Rajnoha 2014-04-04 11:34:57 UTC 
Finally, I've added a better check:

[0] raw/~ $ lvcreate -l1 -My --minor 10 vg
  Logical volume "lvol0" created

[0] raw/~ $ lvcreate -l1 -My --major 254 --minor 11 vg
  Ignoring supplied major number - kernel assigns major numbers dynamically. Using major number 253 instead.
  Logical volume "lvol1" created

[0] raw/~ $ lvs -o+major,minor
