Description Jeff Layton 2017-09-08 14:08:37 UTC

Currently, when you create a new ceph client we also create a CephContext to hold some global information. Each client that ganesha creates is currently creating its own CephContext and those can interfere with one another.

Ensure that we only create a CephContext when one doesn't already exist.

Comment 2 Jeff Layton 2017-09-11 18:27:57 UTC

I see that this was reassigned to cephfs. To be clear, this is _not_ a cephfs specific problem, as far as I can tell. The CephContext is also used by librados, and programs that use it directly will need to be fixed in a similar fashion.

Comment 4 Jeff Layton 2017-10-06 14:19:56 UTC

I've been tracking this in the associated upstream ceph bug (# 21512). There is a pull request in flight now but it needs some review and an ack from one of the authors of that piece of code.

Comment 5 Jeff Layton 2017-10-20 13:59:06 UTC

Upstream set has been merged.

Comment 17 Ramakrishnan Periyasamy 2018-03-19 10:58:13 UTC

Provided qa_ack, clearing needinfo flag.
