With the use of the in-kernel osd library. Implement read/write of data from/to osd-objects according to information specified in the objects-layout. Support for stripping over mirrors with a received stripe_unit. There are however a few constrains which are not supported: 1. Stripe Unit must be a multiple of PAGE_SIZE 2. stripe length (stripe_unit * number_of_stripes) can not be bigger then 32bit. Also support raid-groups and partial-layout. Partial-layout is when not all the groups are received on the line, addressing only a partial range of the file. TODO: Only raid0! raid 4/5/6 support will come at later stage A none supported layout will send IO through the MDS [Important fallout from the last rebase] Signed-off-by: Boaz Harrosh <bharrosh@panasas.com> [gfp_flags] Signed-off-by: Benny Halevy <bhalevy@panasas.com> |
