Submitted for review an exofs support for multiple osd targets in a mirror configuration. Depending on pending scsi/osd patches I would like to push these in the next exofs push-out. I've been playing with some version of these patches for a while now, testing both as stand alone, as well as, exported to pnfs-objects clients. They are now quite stable, though a bit conservative in regard to what more can be done even in simple mirror configuration. The user-mode mkfs.exofs supports almost the full range of pnfs-objects fixtures, but the Kernel driver will only mount a mirror arrangement. Once these go through we are planning support for raids 0, 4, 5, and 6 over mirrors over device groups. See second patch's commit log for some more explanations. The new user-mode utilities as well as these patches can be found at: http://git.open-osd.org/gitweb.cgi?p=open-osd.git;a=summary I will push these patches to linux-next once all comments subside.
