It allows you to build JBOD (concatentation) arrays using the MD RAID subsystem. Could you briefly explain the concept of 'personality' in this context? I see it referred to but i have yet to find an explanation thereof. perhaps i have been looking in the wrong place. I am also motivated by your response to see if i am barking up the wrong tree. :-) I have a need to harness a hard drive like thing that can only be written to in linear fashion using device mapper. I had assumed that i needed to start from the existing linear implementation that is in dm-linear. Am I wrong and everything i need is already coded and i just need to create an appropriate configuration file of some kind? Please advise when you get a chance. Thankyou in advance. johnu <SNIP> Regards, Bryn. -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
