Hi All...
For reasons which are not important here, I have to compile ceph clients
in SL6/Centos6. In a previous thread, I have posted instructions on how
to do that for an Infernalis release. The instructions for Jewel 10.2.1
follow. Maybe someone else may profit from those since Centos6 rele

As long as there hasn't been a change recently Ceph does not store checksums.
Deep scrub compares checksums across replicas.

be to move each image to local d

There was indeed a bug in hammer 0.94.6 that caused data corruption, only
if you were using min_read_recency_for_promote > 1.
That was discussed on the mailing list [0] and fixed in 0.94.7 [1]
AFAIK, infernalis releases were never affected.

Hi,
regarding clustered VyOS on KVM: In theory this sounds like a safe plan,
but will come with a great performance penalty because of all the
context-switches. And even with PCI-passthrough you will also feel
increased latency.

I configure my cluster's crush rulesest according to

Then restart my cluster, things looks like ok.
My tests have not finished.

Hi,
Regarding single points of failure on the daemon on the host I was thinking
about doing a cluster setup with i.e. VyOS on kvm-machines on the host, and
they handle all the ospf stuff as well. I have not done any performance
benchmarks but it should be possible to do at least. Maybe even possib
