In luminous
osd_recovery_threads = osd_disk_threads ?
osd_recovery_sleep = osd_recovery_sleep_hdd ?
Or is this speeding up recovery, a lot different in luminous?

This message seems to be very concerning:
> mds0: Metadata damage detected
but for the rest, the cluster seems still to be recovering. you could
try to seep thing up with ceph tell, like:
ceph tell osd.* injectargs --osd_max_backfills=10
ceph tell osd.* injectargs --osd_recovery_sleep=0.0
ceph tell osd.* injectargs --osd_recovery_threads=2

What are some outputs of commands to show us the state of your
cluster. Most notable is `ceph status` but `ceph osd tree` would be
helpful. What are the size of the pools in your cluster? Are they all
size=3 min_size=2?

Hello,
Today we had a node crash, and looking at it, it seems
there is a
problem with the RAID controller, so it is not coming
back up, maybe
ever. It corrupted the local filesytem for the ceph
storage there.
The remainder of our storage (10.2.10) cluster is
running, and it looks
to be repairing and our min_size is set to 2. Normally,
I would expect
that the system would keep running normally from and end
user
perspective when this happens, but the system is down.
All mounts that
were up when this started look to be stale, and new
mounts give the
following error:
# mount -t ceph ceph-0:/ /test/ -o
name=admin,secretfile=/etc/ceph/admin.secret,noatime,_netdev,rbytes
mount error 5 = Input/output error
Any suggestions?
Dan
