RBD: Missing 1800000000 when map block device

[MinhTien MinhTien <tientienminh080590@xxxxxxxxx>]

Hi all,

When I map block device in client kernel 3.10.93-1.el6.elrepo.x86_64, i get error:

libceph: mon0 ip:6789 feature set mismatch, my 4a042a42 < server's 184a042a42, missing 1800000000

libceph: mon0 ip:6789 socket error on read

I used ceph version 0.87.2

I tried to find the problem in this page: http://cephnotes.ksperis.com/blog/2014/01/21/feature-set-mismatch-error-on-ceph-kernel-client but I not saw infomation for my error.

Please help me,

Thanks you,
