This one (#2, regular release cadence) is the one I will value the most.
Hi Sage,
The one option I do not want for Ceph is the last one: support upgrade
across multiple LTS versions
I'd rather wait 3 months for a better release (both in terms of
functions and quality) than seeing the Ceph team exhausted, having to
maintain for years a lot more releases and code

Very new to Ceph but long time but long time sys admin who is jaded/opinionated.
My 2 cents:
1) This sounds like a perfect thing to put in a poll and ask/beg people to
vote. Hopefully that will get you more of a response from a larger number of
users.

Hi,
I ran a small test two node ceph cluster - 12.2.0 version. It has 28
osds, 1 mon and 2 mgr. It runs fine, however I noticed this strange

Hi,
I have the same problem. A bug [1] is reported since months, but
unfortunately this is not fixed yet. I hope, if more people are having
this problem the developers can reproduce and fix it.
I was using Kernel-RBD with a Cache Tier.

Hi,
we are running a luminous cluster and three radosgw to serve a s3 compatible

Quick drop-in, if this is a suitable solution: rbd-nbd
This will give you, for a small performance cost, a block device using
