I’m trying to understand this situation:
ceph health detail
HEALTH_WARN Reduced data availability: 33 pgs inactive
[WRN] PG_AVAILABILITY: Reduced data availability: 33 pgs inactive
pg 1.0 is stuck inactive for 20h, current state unknown, last acting []
pg 2.0 is stuck inactive for 20h,
So I did this:
ceph osd crush rule create-replicated hdd-rule default rack hdd
[ceph: root@cn01 ceph]# ceph osd crush rule ls
replicated_rule
hdd-rule
ssd-rule
[ceph: root@cn01 ceph]# ceph osd crush rule dump hdd-rule
{
"rule_id": 1,
"rule_name": "hdd-rule",
"ruleset": 1,
Peter,
We're seeing the same issues as you are. We have 2 new hosts Intel(R)
Xeon(R) Gold 6248R CPU @ 3.00GHz w/ 48 cores, 384GB RAM, and 60x 10TB SED
drives and we have tried both 15.2.13 and 16.2.4

FYI, I'm getting monitors assigned via '... apply label:mon' with
current and valid 'mon' tags: 'committing suicide' after surprise
reboots in the 'Pacific' 16.2.4 release. The tag indicating a monitor
should be assigned to that host is present and never changed.
Deleting the mon tag, waiting

There is also a longstanding belief that using cpio saves you context switches

On its face, it seems like cp -a is getting ever so slightly better speed, but
not a clear night and day difference.
I will definitely look into this and report back any findings,
I guess I should probably have been more clear, this is one pool of many, so
the other OSDs aren't idle.
So I don't necessarily think that the PG bump would be the worst thing to try,
but its definitely not as bad as I may have made it sound.
Thanks,
Reed

I’m continuing to read and it’s becoming more clear.
The CRUSH map seems pretty amazing!

This would help us in planning where to place certain datasets based on
popularity, eg on a EC HDD pool or a replicated SSD pool.
I know I can run inotify on the ceph clients, but
I managed by experimenting how to get rid of that wrongly created MDS service,
so for those who are looking for that information too, I used the following
command:

Thank you both for your response. So this leads me to the next question:
ceph osd crush rule create-replicated
What is and in this case?
It also looks like this is responsible for things like “rack awareness” type
attributes which is something I’d like to utilize.:
# types
type 0 osd
Create a crush rule that only chooses non-ssd drives, then
ceph osd pool set crush_rule YourNewRuleName
and it will move over to the non-ssd OSDs.
