That's great news, many thanks - looking forward to it! 
I also noted the CephFS kernel client is now mentioned as "fully supported" 
with the upcoming RHEL 7.6: 
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7-beta/html-single/7.6_release_notes/index#new_features_file_systems
Those release notes still talk about missing quota support, but I guess this 
will then be added soonish :-). 

All the best,
Oliver

We have already backported quota patches to RHEL 3.10 kernel. It may
take some time for redhat to release the new kernel.

Yes, I know that it's part of the official / vanilla kernel as of 4.17. 
However, I was wondering whether this functionality is also likely to be 
backported to the RedHat-maintained kernel which is also used in CentOS 7? 
Even though the kernel version is "stone-aged", it matches CentOS 7's userspace 
and RedHat is taking good care to implement fixes. 

Seeing that even features are backported, it would be really helpful if also 
this functionality would appear as part of CentOS 7.6 / 7.7,
especially since CentOS 8 still appears to be quite some time away. 

Cheers,
Oliver

Your cluster needs to be running Mimic and Linux v4.17+.

It is supported in mainline kernel from elrepo.

[ceph-users] CephFS Quota and ACL support

[Oliver Freyermuth]

Dear Cephalopodians,

sorry if this is the wrong place to ask - but does somebody know if the 
recently added quota support in the kernel client,
and the ACL support, are going to be backported to RHEL 7 / CentOS 7 kernels? 
Or can someone redirect me to the correct place to ask? 
We don't have a RHEL subscription, but are using CentOS. 

These features are critical for us, so right now we use the Fuse client. My 
hope is CentOS 8 will use a recent enough kernel
to get those features automatically, though. 

Cheers and thanks,
Oliver
