If you wish to use it you will need to install libdevmapper: ftp://ftp.sistina.com/pub/LVM2/device-mapper/device-mapper-latest.tgz and then either use dmsetup, or the LVM tools: ftp://ftp.sistina.com/pub/LVM2/tools/LVM2.0-latest.tgz Initial testing has been successful, though it hasn't been exercised nearly as much as the stable 2.4 releases. There is a chunk of ~50 lines in dm.c, which I have clearly labelled, this is stop gap block splitting code that will be replaced with the correct use of queue->merge_bvec_fn etc. However before I can make this change there are a couple of other patches to the block layer that I want to merge. Since the feature freeze is looming I would appreciate it if this code was merged now. Allowing me to patch/argue to get the extra performance at my leisure. Good plan ?

ChangeSet@1.713, 2002-10-09 17:36:55+01:00, thornber@sistina.com [Device mapper] The stripe target. Maps a range of logical sectors across many physical volumes.
