Re: which CentOS 7 kernel is compatible with jewel?

"rbd ls" does work with 4.6 (just tested with 4.6.1-1.el7.elrepo.x86_64). That's against a 10.2.0 cluster with ceph-common-10.2.0-0

What's the error you're getting? Are you using default rbd pool or specifying pool with '-p'? I'd recommend checking your ceph-common package.

Thanks,

Hi Everyone,
I’ve been running jewel for a while now, with tunables set to hammer.  However, I want to test the new features but cannot find a fully compatible Kernel for CentOS 7.  I’ve tried a few of the elrepo kernels - elrepo-kernel 4.6 works perfectly in CentOS 6, but not CentOS 7.  I’ve tried 3.10, 4.3, 4.5, and 4.6.

What does seem to work with the 4.6 kernel is mounting, read/write to a cephfs, and rbd map / mounting works also.  I just can’t do 'rbd ls'

'rbd ls' does not work with 4.6 kernel but it does work with the stock 3.10 kernel.
'rbd mount' does not work with the stock 3.10 kernel, but works with the 4.6 kernel.

Very odd.  Any advice?

Thanks!
