Description stolen from linux d/b/rbd.c L3:
rbd.c -- Export ceph rados objects as a Linux block device
16 partitions seem to make sense according to L90:
#define RBD_SINGLE_MAJOR_PART_SHIFT 4
Running *scan -vvvvvvdddddd yields
#filters/filter-type.c:28 /dev/rbd1p5: Skipping: Unrecognised LVM device type 252
#filters/filter-persistent.c:131 filter caching bad /dev/rbd1p5
right now, and adding
types = ["rbd", 252]
to /e/l/lvm.conf (with the matching "252 rbd" in /p/devices) works as a
per-machine fix:
rbd1 252:16 0 1T 1 disk
|-rbd1p1 252:17 0 243M 1 part
|-rbd1p2 252:18 0 1K 1 part
`-rbd1p5 252:21 0 1023.8G 1 part
`-dev01--vg-root 253:0 0 1023.8G 0 lvm
but rbd is supported by upstream so it'd be nice to have it work OOB
