libceph: rename ceph_osd_request::r_{oloc,oid} to r_base_{oloc,oid} · 3c972c95

由 Ilya Dryomov 提交于 1月 27, 2014

Rename ceph_osd_request::r_{oloc,oid} to r_base_{oloc,oid} before
introducing r_target_{oloc,oid} needed for redirects.

libceph: introduce and start using oid abstraction · 4295f221

由 Ilya Dryomov 提交于 1月 27, 2014

In preparation for tiering support, which would require having two
(base and target) object names for each osd request and also copying
those names around, introduce struct ceph_object_id (oid) and a couple
helpers to facilitate those copies and encapsulate the fact that object
name is not necessarily a NUL-terminated string.

libceph: start using oloc abstraction · 22116525

由 Ilya Dryomov 提交于 1月 27, 2014

Instead of relying on pool fields in ceph_file_layout (for mapping) and
ceph_pg (for enconding), start using ceph_object_locator (oloc)
abstraction.  Note that userspace oloc currently consists of pool, key,
nspace and hash fields, while this one contains only a pool.  This is
OK, because at this point we only send (i.e. encode) olocs and never
have to receive (i.e. decode) them.

This makes keeping a copy of ceph_file_layout in every osd request
unnecessary, so ceph_osd_request::r_file_layout field is nuked.

rbd: enable extended devt in single-major mode · 7e513d43

由 Ilya Dryomov 提交于 12月 16, 2013

If single-major device number allocation scheme is turned on, instead
of reserving 256 minors per device, which imposes a limit of 4096
images mapped at once, reserve 16 minors per device and enable extended
devt feature.  This results in a theoretical limit of 65536 images
mapped at once, and still allows to have more than 15 partititions:
partitions starting with 16th are mapped under major 259 (Block
Extended Major):

$ rbd showmapped
id pool image snap device
0  rbd  b5    -    /dev/rbd0    # no partitions
1  rbd  b2    -    /dev/rbd1    # 40 partitions
2  rbd  b3    -    /dev/rbd2    #  2 partitions

$ cat /proc/partitions
