| * libceph: primary_temp infrastructureIlya Dryomov2014-04-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add primary_temp mappings infrastructure. struct ceph_pg_mapping is overloaded, primary_temp mappings are stored in an rb-tree, rooted at ceph_osdmap, in a manner similar to pg_temp mappings. Dump primary_temp mappings to /sys/kernel/debug/ceph/<client>/osdmap, one 'primary_temp <pgid> <osd>' per line, e.g: primary_temp 2.6 4 Signed-off-by: Ilya Dryomov <ilya.dryomov@inktank.com> Reviewed-by: Alex Elder <elder@linaro.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current crush_choose_firstn code will re-use the same 'r' value for the recursive call. That means that if we are hitting a collision or rejection for some reason (say, an OSD that is marked out) and need to retry, we will keep making the same (bad) choice in that recursive selection. Introduce a tunable that fixes that behavior by incorporating the parent 'r' value into the recursive starting point, so that a different path will be taken in subsequent placement attempts. Note that this was done from the get-go for the new crush_choose_indep algorithm. This was exposed by a user who was seeing PGs stuck in active+remapped after reweight-by-utilization because the up set mapped to a single OSD.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Back in 27f4d1f6bc32c2ed7b2c5080cbd58b14df622607 we refactored the CRUSH code to allow adjustment of the retry counts on a per-pool basis. That commit had an off-by-one bug: the previous "tries" counter was a *retry* count, not a *try* count, but the new code was passing in 1 meaning there should be no retries. Fix the ftotal vs tries comparison to use < instead of <= to fix the problem. Note that the original code used <= here, which means the global "choose_total_tries" tunable is actually counting retries. Compensate for that by adding 1 in crush_do_rule when we pull the tunable into the local variable. This was noticed looking at output from a user provided osdmap. Unfortunately the map doesn't illustrate the change in mapping behavior and I haven't managed to construct one yet that does. Inspection of the crush debug output now aligns with prior versions, though. Reflects ceph.git commit 795704fd615f0b008dcc81aa088a859b2d075138.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is primarily for rbd's benefit and is supposed to combat fragmentation: "... knowing that rbd images have a 4m size, librbd can pass a hint that will let the osd do the xfs allocation size ioctl on new files so that they are allocated in 1m or 4m chunks. We've seen cases where users with rbd workloads have very high levels of fragmentation in xfs and this would mitigate that and probably have a pretty nice performance benefit." SETALLOCHINT is considered advisory, so our backwards compatibility mechanism here is to set FAILOK flag for all SETALLOCHINT ops.
