Description of problem:
With the latest 6.1 RPMS created a few clustered LVs.  They are
displaying in /proc/partitions as "diapered_dm" with these mammoth sizes.

Comment 1 Alasdair Kergon 2005-01-05 09:23:22 EST
What are major numbers 252 and 253 assigned to in /proc/devices?

2.6 device-mapper only supports one major number at the moment
Comment 2 Alasdair Kergon 2005-01-05 09:24:30 EST
And what does 'dmsetup info -c' report?
Comment 3 Derek Anderson 2005-01-05 11:15:57 EST
From /proc/devices: 
 
252 gfs_diaper 
Comment 4 Ken Preslan 2005-01-05 14:33:50 EST
That's the way they are and always will be.
