Hi Milan
Please DO NOT delete the object for all the EC shards (i.e. at all three
OSDs)
Sorry, I missed that you have three shards crashing... Removing that
many object shards will cause data lost.
Theoretically removing just a single object replica and then doing a
scrub might help t
Interesting. There is a more forceful way to disable progress which I had
to do as we have an older version. Basically, you stop the mgrs, and then
move the progress module files:
systemctl stop ceph-mgr.target
mv /usr/share//ceph/mgr/progress {some backup location}
systemctl start ceph-mgr.target
Hi Paul,
We had similar experience with redhat ceph, and it turned out to be the mgr

thought would impact you seems to be in 14.2.11.

While the "progress off" was hung, I did a systemctl restart of the active
ceph-mgr. The progress toggle command completed and reported that progress
disabled.
All commands that were hanging before are still unresponsive. That was worth a
shot.
Thanks

Can you clarify, Istvan, what you plan on setting to 64K? If it’s the number of
shards for a bucket, that would be a mistake.

Hi,
I did some search about replacing osd, and found some different

Ever since we jumped from 14.2.9 to .12 (and beyond) a lot of the ceph commands
just hang. The mgr daemon also just stops responding to our Prometheus scrapes
occasionally. A daemon restart and it wakes back up. I have nothing pointing

Hi guys,
I was looking at some Huawei ARM-based servers and the datasheets are
very interesting. The high CPU core numbers and the SoC architecture
should be ideal for a distributed storage like Ceph, at least in theory.

I want to just echo this sentiment. I thought the lack of older docs would
be a very temporary issue, but they are still not available. It is
especially frustrating when half the google searches also return a page not
found error. The migration has been very badly done.
Sincerely,

I am gathering prometheus metrics from my (unhealthy) Octopus (15.2.4)
cluster and notice a discrepency (or misunderstanding) with the ceph
dashboard.
In the dashboard, and with ceph -s, it reports 807 million objects objects:
pgs: 169747/807333195 objects degraded (0.021%)

Personally I have not run Ceph on ARM, but there are companies selling
such setups:
https://softiron.com/
https://www.ambedded.com.tw/
At least in the past, there have been a couple of things you really want
to focus on regarding ARM and performance (beyond the obvious core
count/clockspeed/ipc/etc):
1) HW acceleration for things like CRC32, MD5, etc
2) context switching overhead
3) memory throughput

This bug may be affect when you upgrade from 14.2.11 to 14.2.(12|14) with low
speed (e.g. one by one node). If you already upgrade from 14.2.11 you just jump
