Description

I've been experimenting with ceph erasure pools. In my naivety I created an erasure pool with a dash in the name. Example:

ceph osd erasure-code-profile set myprofile-wide k=3 m=2 ruleset-failure-domain=rack

The pool fails to create because the pg's never get created. They get stuck in incomplete-creating. I did a query on a few of the pgs and it's not apparent what is wrong. They don't appear to be stuck or waiting on anything. When I delete the pool and recreate the same thing without the dash in the name it goes through just fine. I think the ceph tool should deny invalid names. Here's what the command returns when you query the erasure profile after creating it.


ceph osd erasure-code-profile get ceph-wide
directory=/usr/lib/x86_64-linux-gnu/ceph/erasure-code
k=10
m=3
plugin=jerasure
ceph-wide=
ruleset-failure-domain=osd
technique=reed_sol_van

I tried the following and the problem does not show. It would be great if you could provide me with a sequence of commands to reproduce the problem. Thanks :-)
