Thank you for your answer! We will use size=4 and min_size=2, which should
do the trick.
For the monitor issue, we have a third datacenter (with higher latency, but
that shouldn't be a problem for the monitors)
We had also considered the locality issue. Our WAN round trip latency is
1.5 ms (now)
Hi,

I'm assuming you mean from the server: you can list the clients of an
MDS by SSHing to the server where it's running and doing "ceph daemon
mds. session ls". This has been in releases since Giant iirc.

AFAIK straw_calc_version = 1 is the optimal. straw_calc_version = 2 is

Hi,
depending on cache mode etc - from what we have also experienced (using

cache configuration.
This means, we were also unable to deploy new VMs (base-gold snapshot is

Follow the instructions here to set up a filesystem:

Hi,
Since the security notice regarding ceph.com the mirroring system broke.
This meant that eu.ceph.com didn't serve new packages since the whole
download system changed.
I didn't have much time to fix this, but today I resolved it by
installing Varnish [0] on eu.ceph.com

I think you will be OK, but you should double check on a test cluster.
You should be able to revert the rulesets if the data isn't found.

Ceph-disk (which ceph-deploy uses), uses GPT to partition OSDs so that
they can be automatically started by udev and reference partitions for
journals using unique identifiers. The necessary data to start the
OSD, the auth key, fsid, etc, are stored

Hi Lindsay,
This is usually indicative of the same tracepoint event being included by both
a static and dynamic library. See the following thread regarding this issue
within Ceph when LTTng-ust was first integrated [1]. Since I don't have any
insight into your application, are you somehow linking against

Hi ceph users,
I am using CephFS for file storage and I have noticed that the data gets
distributed very unevenly across OSDs.

Hello Andras,
Some initial observations and questions:
The total PG recommendation for this cluster would actually be 8192 PGs per the
formula.
Total PG's = (90 * 100) / 2 = 4500
Next power of 2 = 8192.
The result should be rounded up to the nearest power of two. Rounding up is
optional,
Hi Michael,
I could certainly double the total PG count, but and it probably will
reduce the discrepancies somewhat, but I wonder if it would be all that
different. I could of course be very wrong.

Do you have a core file from the crash? If you do and can find out
which pointers are invalid that would help...I think "cct" must be the
broken one, but maybe it's just the Inode* or something.
