Re: What's the minimal version of "ceph" client side the current "jewel" release would support?

[Bob R <bobr@xxxxxxxxxxxxxx>]

Yang,

We've got some proxmox hosts which are still running firefly and appear to be working fine with Jewel. We did have a problem where the firefly clients wouldn't communicate with the ceph cluster due to mismatched capabilities flags but this was resolved by setting "ceph osd crush tunables legacy". Note that moving from optimal tunables to legacy did shuffle quite a bit of data.

See title.

We have Firefly on the client side (SLES11SP3) and it does not seem to work well with the "jewel" server nodes (CentOS 7)

Can somebody please provide some guidelines?

Thanks,

Yang
