Abosolutely. I’ve done this both with Trusty -> Bionic and Precise -> RHEL7.

Hi all,
I have a 39 node, 1404 spinning disk Ceph Mimic cluster across 6 racks
for a total of 9.1PiB raw and about 40% utilized. These storage nodes
started their life on Ubuntu 14.04 and in-place upgraded to 16.04 2
years ago however I have started a project to do fresh installs of
each OSD node
Good day,
rw operations (randwrite 4kB and 4MB) over mapped RBD are just too slow. I
am also using librbd over TGT.
fio input:
[global]
rw=randwrite
ioengine=libaio
iodepth=64
size=1g
direct=1
buffered=0
startdelay=5
group_reporting=1
thread=1
ramp_time=5

Hi,
huge read amplification for index buckets is unfortunately normal,
complexity of a read request is O(n) where n is the number of objects in
that bucket.
I've worked on many clusters with huge buckets and having 10 gbit/s of
network traffic between the OSDs and radosgw is unfortunately not unus
