Hi,

there's no attachment to your email, please use something like pastebin to provide OSD logs.

Thanks

Hi,

I ended up with having whole set of osds to get back original ceph cluster.
I figured out to make the cluster running. However, it's status is
something as below:

bash-4.4$ ceph -s

  cluster:

    id:     3f271841-6188-47c1-b3fd-90fd4f978c76

    health: HEALTH_WARN

            7 daemons have recently crashed

            4 slow ops, oldest one blocked for 35077 sec, daemons
[mon.a,mon.b] have slow ops.



  services:

    mon: 3 daemons, quorum a,b,d (age 9h)

    mgr: b(active, since 14h), standbys: a

    osd: 4 osds: 0 up, 4 in (since 9h)



  data:

    pools:   0 pools, 0 pgs

    objects: 0 objects, 0 B

    usage:   0 B used, 0 B / 0 B avail

    pgs:


All osds are down.


I checked the osds logs and attached with this.


Please help and I wonder if it's possible to get the cluster back. I have
some backup for monitor's data. Till now I haven't restore that in the
course.


Thanks,

Ben
