Comment #3 on issue 1180 by [email protected]: Ceph/RBD support is broken
with Ceph 'Jewel' due to incorrect showmapped command
https://code.google.com/p/ganeti/issues/detail?id=1180
I know almost nothing about ceph, but just looking at the sources for
hammer and jewel, it does appear that the rbd command line tool in jewel
lost the --pool/-p option that hammer had.
I think your fix isn't going to work entirely properly though. What happens
if you have two mappings in different pools that happen to have the same
name? I think you're going to have to change _ParseRbdShowmappedJson to
filter out mappings from the specified pool.
Also, it looks like the rbd subcommands create, rm, map, resize, import and
export also have the same problem. In hammer you can do rbd $SUB_CMD -p
mypool mymap or rbd $SUB_CMD mypool/mymap (the parsing of the second is
implemented by set_pool_image_name(...) in src/rbd.cc).
In jewel only the second syntax appears to be supported (again, just by
eyeballing the source code).
I think that you're going to need to update Create, Remove,
_MapVolumeToBlockdev, Close, Import and Export in RADOSBlockDevice to use
the mypool/mymap syntax.
David, do you have any input on this?
