[linux-lvm] Disk /dev/dm-0 doesn't contain a valid partition table



Hello,

 

I did an fdisk -l to review my partition table (see results below), and found four entries that end with "Disk /dev/dm-X doesn't contain a valid partition table."  I don't recall seeing this in the past, so I believe it is something new.

 

I recently began using kernel 2.6.21.1, up from 2.6.9-42.  I don't know if perhaps this had some effect, or if the entries are normal and I just never noticed them.

 

What led me here is that sar -d output includes four entries for hard drives (dev253 entries) when there are only three on my system.  Fdisk is reporting four DM devices, so I'm thinking there is some correlation, but I don't know what.

 

Any constructrive feedback would be appreciated.

 

Thank you.
