I assume this is the right Way. I had done a Disaster Recovery test a few months ago with Jewel on an only OSD Server. Just reinstall the OS an than ceph. Do not Touch the osds they will automatically Start.

It happens to my that OS being corrupted.
I just reinstalled the OS and deploy the monitor.
While I was going for zap and reinstal OSD I found that my OSD were already running again.

Magically

Hi Iban,

Is the monitor data safe? If it is, just install jewel in other servers and plug in the OSD disks, it should work.

Hi,

  We have a serious issue. We have a mini cluster (jewel version) with two server (Dell RX730), with 16Bays and the OS intalled on dual 8 GB sd card, But this configuration is working really really bad.

  The replication is 2, but yesterday one server crash and this morning the other One, this is not the first time, but others we had one server up and the data could be replicated without any troubles, reinstalling the osdserver completely.

  Until I understand, Ceph data and metadata is still on bays (data on SATA and metadata on 2 fast SSDs), I think only the OS installed on SD cards is corrupted.

  Is there any way to solve this situation?

  Any Idea will be great!!

Regards, I
