hi, professor
Recently, i am intend to make big adaption for local small-scale ceph
cluster. The job mainly includes two parts:
(1) mds metadata: switch metadata storage medium to ssd.
(2) osd bluestore wal: switch wal storage medium to ssd.
now, we are doing some research and test
Hello cephers,

We recently updated from ceph 12.2.4 to 12.2.10, updated Ubuntu 16.04 to the
latest patchlevel (with kernel 4.15.0-43) and applied dell firmware 2.8.0.
On 12.2.5 (before updating the cluster) we had in a frequency of

The hope is to be able to provide scale-out storage, that will be performant
enough to use as a primary fs-based data store for research data (right now we
mount via NFS on our cluster nodes, may do that with Ceph or perhaps do native
cephfs access from the cluster nodes.) Right now I’m still

At Heinlein Support we also offer independent

The "rbdmap" unit needs rbdmap and fstab to be configured for each volume, what
if the map and mount are done by applications instead of the system unit? See,
we don't write each volume info into /etc/ceph/rbdmap /etc/fstab, and if the
"rbdmap" systemd unit is stopped unexpected, not by
Upgrading to 4.15.0-43-generic fixed the problem.
