are there any incompatibilities related to mdadm? does it only support the md driver at a certain level? our software supports kernel version 2.2 and later. does it fully support creating a raid device on logical volumes, and creating logical volumes on raid devices? i have played with this a little and havent seen any problems but i thought i would ask to see if anyone has seen anything. would i expect to see the mdadm executable available on most distributions today by default? i realize that raid devices created with raidtools and raid devices created with mdadm can co-exist. is there an easy way to know which method was used to create them? thanks for the responses On Tue, 2004-08-31 at 12:38, Rechenberg, Andrew wrote: > I currently use a combination of raidtools and mdadm.
