Hello everyone,
I am facing a situation that I have not yet been able to find a solution
for.
There is a client machine that is running a parallel job that generates an
output file over time.
The problem is that a file with the same name is being generated. There
are two files wit
Hi,
I just did a new Ceph installation and would like to enable the "read
balancer".
However, the documentation requires that the minimum client version be
reef. I checked this information through "ceph features" and came across the
situation of having 2 luminous clients.

What is a “storage server”?
These are machines that only have the operating system and ceph installed.

These 2 IPs are from the storage servers.
There are no user processes running on them. It only has the operating system and ceph installed.

Hi Janne,
That's it.
When finished rebalancing, the space looked as expected.
Thank you.

Hello,
I recently installed a new cluster.
After the first node was working, I started transferring the files I
needed. As I was in some urgency to do rsync, I enabled size=1 for the CephFS
data pool.
After a few days, when I managed to place a new node, I put size = 2 for
that
I need.

Hi Kyriazis,
I work with a cluster similar to yours : 142 HDDs and 18 SSDs.
I had a lot of performance gains when I made the following settings:

Hello,
After some time, I'm adding some more disks on a new machine in the ceph
cluster.
However, there is a container that is not rising. It is the
"node-exporter".
Below is an excerpt from the log that reports the error:

Hi,
I upgraded a cluster 2 weeks ago here. The situation is the same as Michel.
