libceph: mon_get_version request infrastructure

2014-06-06T01:29:57Z

Add support for mon_get_version requests to libceph. This reuses much of the ceph_mon_generic_request infrastructure, with one exception. Older OSDs don't set mon_get_version reply hdr->tid even if the original request had a non-zero tid, which makes it impossible to lookup ceph_mon_generic_request contexts by tid in get_generic_reply() for such replies. As a workaround, we allocate a reply message on the reply path. This can probably interfere with revoke, but I don't see a better way. Signed-off-by: Ilya Dryomov Reviewed-by: Sage Weil

libceph: recognize poolop requests in debugfs

libceph: dump pool {read,write}_tier to debugfs

libceph: primary_affinity infrastructure

2014-04-05T04:08:02Z

Add primary_affinity infrastructure. primary_affinity values are stored in an max_osd-sized array, hanging off ceph_osdmap, similar to a osd_weight array. Introduce {get,set}_primary_affinity() helpers, primarily to return CEPH_OSD_DEFAULT_PRIMARY_AFFINITY when no affinity has been set and to abstract out osd_primary_affinity array allocation and initialization.

libceph: primary_temp infrastructure

2014-04-05T04:07:58Z

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//osdmap, one 'primary_temp ' per line, e.g: primary_temp 2.6 4 Signed-off-by: Ilya Dryomov Reviewed-by: Alex Elder

libceph: generalize ceph_pg_mapping

In preparation for adding support for primary_temp mappings, generalize struct ceph_pg_mapping so it can hold mappings other than pg_temp. Signed-off-by: Ilya Dryomov Reviewed-by: Alex Elder
