I thought that recovery below min_size for EC pools wasn't expected to work
until Octopus. From the Octopus release notes:

Hello,
in between ceph is runing again normally, except for the two osds that
are down because of the failed disks.
What really helped in my situation was to lower min_size from 5 (k+1)
to 4 in my 4+2 erasure code setup. So I am also greatful for the
programmer who put the helping hint in c

the option is actually set. On one of my monitors:

"osd_allow_recovery_below_min_size": "true",
Thank you very much

Hi,
from what you've sent my conclusion about the stalled I/O would be
indeed the min_size of the EC pool.
There's only one PG reported as incomplete, I assume that is the EC
pool, not the replicated pxa-rbd, right? Both pools are for rbd so I'm
guessing the rbd headers are in pxa-rbd while
