I have installed cpeh 19.2 squid release and would like to use some new features.
Best I can tell erasure coding has 2 new features that look useful to me.
crush-num-failure-domains=
crush-osds-per-failure-domain=
I can't currently find how I learned about these but I think it may do some sort of custom crushmap rule when used.
When I used it to create an erasure coded pool
I set
But then no cephfs can mount in proxmox or any other client I have tried so far.
I think it's because the kernel client is not the 19.2 version? But I can't tell what kernel would have the correct version. or why proxmox would install 19.2 but not be able to mount a 19.2 cephfs.
I get this error if trying to mount
can anyone else set ceph osd set-require-min-compat-client squid and confirm cephfs does not work?
It appears the ceph install is set to minimum client version luminous seems very old
