Hi John Spray,
Now I am able to update the max_misplaced parameter successfully and
validating it.
We are using balancer with mode upmap and it starts redistributing the PGs.
We observed like the backfilling wait increases a lot , can we create any
plan in balancer to restrict the PG backfilling

if you still cannot install the ceph RPMs, becuse of that dependency,
do as Ruben suggests - install selinux-policy-targeted
Then you use the RPM option --nodeps which will ignore the dependency
requirements.
Do not be afraid to use this option - and do not use it blindly either.

Hi All,
after every reboot the current superblock etc folders get deleted from
/var/lib/ceph/osd/ceph-0(1,etc)
.I have to prepare and activate osd after every reboot. Any suggestions?
ceph.target and ceph-osd are enabled.
Thanks in advance!

Hi Ruben and community.
Thanks a lot for all the help and hints. Finally I figured out that "base" is
also part of i.e. "selinux-policy-minimum". After installing this pkg via "yum
install", the usual "ceph installation" continues...
Seems like the "ceph packaging" is too much RHEL oriented ;)

Hi all,
Slowly getting round to migrating clusters to Bluestore but I am interested
in how people are handling the potential change in write latency coming from
Filestore? Or maybe nobody is really seeing much difference?
As we all know, in
Which version of ceph, filestore or bluestore, did you use ceph-disk,
ceph-volume, or something else to configure the osds, did you use lvm, is
there encryption or any other later involved?

Hi Nick,
Our latency probe results (4kB rados bench) didn't change noticeably
after converting a test cluster from FileStore (sata SSD journal) to
BlueStore (sata SSD db). Those 4kB writes take 3-4ms on average from a
random VM in our data centre. (So bluestore DB seems equivalent to

The process to create an encrypted bluestore OSD is very simple to make
them utilize dmcrypt (literally just add --dmcrypt to the exact same
command you would run normally to create the OSD). The gotcha is that I
had to find the option by using --help with ceph-volume from the cli. I
was unable t

Please keep the mailing list in your responses. What steps did you follow
when configuring your osds.
