Description Derek Anderson 2005-01-04 19:49:32 UTC

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.

Additional info:

Comment 1 Alasdair Kergon 2005-01-05 14:23:22 UTC

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 14:24:30 UTC

And what does 'dmsetup info -c' report?

Comment 3 Derek Anderson 2005-01-05 16:15:57 UTC

From /proc/devices: 
 
252 gfs_diaper

Comment 4 Ken Preslan 2005-01-05 19:33:50 UTC

That's the way they are and always will be.
