I find this message in dmesg:
[83090.212918] libceph: mon0 192.168.159.128:6789 feature set mismatch, my 4a042a42 < server's 2004a042a42, missing 20000000000
According to "http://cephnotes.ksperis.com/blog/2014/01/21/feature-set-mismatch-error-on-ceph-kernel-client",
this could mean that I need to upgrade kernel client up to 3.15 or disable tunable 3 features.
Our cluster is not convenient to upgrade.
Could you tell me how to disable tunable 3 features?
Thanks!
Kind Regards, Haitao Wang
