What I found when building a test case for EC is that after using the mon_command to create the pool I need to use wait_for_latest_osdmap() in order to wait for the change to propagate. The replicated pool test case using pool_create() doesn’t need to wait_for_latest_osdmap(). Should we be deprecating librados calls in favor of the very generic mon_command() interface? I would suggest that we add the appropriate librados features to manipulate erasure coded pools.

What do you have in mind ? There are osd erasure-code-profile, osd crush rule create-erasure and the additional arguments to osd pool create can be used with rados_mon_command (or mon_command with the suggested implicit wait_for_latest_osdmap ). Anything else ? https://github.com/ceph/ceph/blob/master/doc/dev/erasure-coded-pool.rst Cheers > > David Zafman > Senior Developer > http://www.inktank.com > > -- > To unsubscribe from this list: send the line "unsubscribe ceph-devel" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html > -- Loïc Dachary, Artisan Logiciel Libre [-- Attachment #2: OpenPGP digital signature --] [-- Type: application/pgp-signature, Size: 263 bytes --] ^ permalink raw reply [flat|nested] 2+ messages in thread
