Is there a maximum number of paths supported by the device mapper ? I have a setup with 12 paths to 14 luns. I had to reduce the number of paths to 10 for the device mapper to startup correctly.
i have seen such problems with linux kernel 2.4, long ago, when max SCSI disk devices was 256 (and hence - also max paths for such devices).
if you're not using SCSI, but rather some other type of device - it could be a limitation of the specific low level driver.
which kernel are you using? and which linux distribution? and what kind of block devices do your disks reside on?
