Thanks, Robert, for sharing so many experience! I feel like I don't deserve
it :)
I have another but very same situation which I don't understand.
Last time i tried to hard kill OSD daemons.
This time i add a new node with 2 OSDs to my cluster and also monitor the
IO. I wrote a script which adds

Hash: SHA256
Can you provide the output of the CRUSH map and a copy of the script
that you are using to add the OSDs? Can you also provide the pool size
and pool min_size?

Comment:
I have 42 OSDs on 6 servers. I'm planning to double that this quarter by
adding 6 more servers to get to 84 OSDs.
I have 3 monitor VMs. Two of them are running on two different blades in
the same chassis, but their networking is on different fabrics. The third
one is on a blade in a different

Interesting. The 'rbd diff' operation uses the same librbd API method as 'rbd
export-diff' to calculate all the updated image extents, so it's very strange
that one works and the other doesn't given that you have a validly formatted
export. I tried to recreate your issues on Giant and was

I have copied two of my pools recently, because old ones has too many pgs.
Both of them contains RBD images, with 1GB and ~30GB of data.
Hi!
I am trying to get behind the values in ceph -w, especially those
regarding throughput(?) at the end:

You should be able to do just that. We recently upgraded from Firefly
to Hammer like that. Follow the order described on the website.
Monitors, OSDs, MDSs.
Notice that the Debian packages do not restart running daemons, but
they _do_ start up not running ones. So say for some reason before
Hi ,
I encountered other problems when i installed ceph .
#1. When i run the command , ceph-deploy new ceph-0, and got
the ceph.conf
file . However , there is not any information aboutosd pool default
size or public network .
[root@ceph-2 my-cluster]# more ceph.conf
[global]
Hi,
1. The network problem has been partly resovled, we removed bonding of Juno
node (Ceph client side), and now IO comes back:
[root@controller fio-rbd]# rados bench -p test 30 seq
sec Cur ops started finished avg MB/s cur MB/s last lat avg lat
0 0 0 0
I tend to use something along the lines
for osd in $(grep osd /etc/mtab | cut -d ' ' -f 2); do echo $(echo $osd | cut
-d '-' -f 2): $(readlink -f $(readlink $osd/journal));done | sort -k 2
Cheers,
Josef
