[linux-lvm] dac960+2.2.19 issue with 1.0.1-rc2

[Jesse Sipprell]

It appears that rc2 consults /proc/devices when determining the block type of
a device in lvm_get_device_type().  The device_names[] array in this function
indicates that the device name for a mylex dac960 array controller should be 
"dac960", however under 2.2.19, /proc/devices indicates that the "name" for 
major device 48 is "rd" and not "dac960". 

I'm assuming that the code was based on a 2.4 kernel, however I don't have a 
2.4 box handy that has dac960 support compiled in, so I cannot verify this.

The end result is that PV operations cannot be performed on a dac960 device; 
tools typically emit "invalid physical volume name".

The following patch addresses the issue although, as should be obvious from
above, I have in no way verified this under kernels > 2.2.19.
