How did this get damaged? You had 3x replication on the pool?

Yep - x3 replica on meta-data pools
We have 4 clusters (all running same version) and have experienced meta-data
corruption on the majority of them at some time or the other - normally a scan

Hi all,
We use ceph(luminous) + openstack(queens) in my test environment。The
virtual machine does not start properly after the disaster test and the image

I have a fresh ceph 14.2.1 cluster up and running based on Ubuntu 18.04.
It consists of 9 hosts (+1 admin host). The nine hosts have each 16
ceph-osd daemons running, three in these nine hosts also have
a ceph-mon and a ceph-mgr daemon running. So three hosts are running
osd, mon and also mgr daemo

Basically they max out at around 1000 IOPS and report 100%
utilization and feel slow.
Haven't seen the 5200 yet.
Micron 5100s performs wonderfully!
You have to just turn its write cache off:
hdparm -W 0 /dev/sdX
1000 IOPS means you haven't done it. Although even with write cache
enabled I o

Hello,
I have a ceph cluster running over 2 years and the monitor began crash
since yesterday. I had some flapping OSDs up and down occasionally,
sometimes I need to rebuild the OSD. I found 3 OSDs are down yesterday,
they may cause this issue or may not.
Ceph Version: 12.2.12, ( upgraded from 12
Late question, but I am noticing
ceph-volume: automatic VDO detection
Does this mean that the OSD layer will at some point support
deployment with VDO?
Or that one could build on top of VDO devices and Ceph would detect
this and report somewhere?
Best,

Thank your help, jason
I find the reason.The exclusive-lock of image do not release after the
disaster test. I release the exclusive-lock then The virtual machine start
properly,and it can also create snap with nova user.

Hello Rainer,
most of the time you just install the newer versions an restart the
old ones without having to worry about the sequence.
Otherwise just use a management solution that helps you with any
day-to-day operation including the complete software update part.
Something like you can see in t
Hi.
This is more an inquiry to figure out how our current setup compares
to other setups. I have a 3 x replicated SSD pool with RBD images.
When running fio on /tmp I'm interested in seeing how much IOPS a
single thread can get - as Ceph scales up very nicely with concurrency.
