Hello Oliver, this issue showed very hard to reproduce, i couldn't make it
again.
My best guess is something with the Azure's network since last week (when
happened a lot) there were a ongoing maintenance.
Here's the outputs:
$ ceph -s
cluster 25736883-dbf1-4d7a-8796-50e36f9de7a6

Hi Diego,
ok so this is a new case scenario.
Before you said its "until i put some load on it".
Now you say, you can't reproduce it and mention that it happends during
a (known) network maintenance.
So i agree with you, we can assume that your problems were based on
network issues.
Thats also
Hello Oliver, sorry if i wasn't clear at my first post.
I agree with you that a network issue isn't desirable but should it crash
mount clients? I mean, doesn't the client be smart enough to retry
connection or so?
My point is cloud environments (public) doesn't have the same availability
as a loca
Hi Diego,
you can see the network connection as your HDD cables.
So if you get interruptions there, its like you are pulling out the HDD
cables of your server/computer and putting it back.
You can just check easily how much your server/computer will like that
with your local HDD's ;-)
And
Ok, i got it.
Having a stable network will save the system from a node crash? What
happens if a osd goes down? Will the clients suffer from freeze mounts and
things like that?
Just asking dummy questions to see if i'm the right path, since AFAIK ceph
is meant to be a high available/fault tolerant
sorry, should copy the list.

Hi Diego,
IF a OSD goes down a hill and IF there are currently read/write requests
on it, THEN you will have again the "pull the plug" event.
Means again, read only mount of filesystem / IO Errors on that specific VM.

All,
I am trying to use ceph-deploy to create an OSD on a multipath device but put
the journal partition on the SSD the system boots from.
I have created a partition on the SSD (/dev/sda5) but ceph-deploy does not seem
to like it.
I am trying:
ceph-deploy osd create ceph01:/dev/mapper/mpathb:/d

Vaguely reminds me of the E2BIG from that one issue way-back-when in

Not quite. The clients will use the "mon initial members" value to
populate their search set, but other config options can fill it as
well
At the Ceph day back to June 10th, 2014, there was a presentation done
by Mellanox.
This presentation was really good. They used xio-firefly branch.
The following link would help you.

Calvin,
What does your crushmap look like?
ceph osd tree
I find it strange that 1023 PGs are undersized when only one OSD failed.

That was it. I had recently rebuilt the OSD hosts and completely forgot to
configure the firewall.
