Hello,
I'm in the process of building a new ceph cluster, this time around i
was considering going with nvme ssd drives.
In searching for something in the line of 1TB per ssd drive, i found
"Samsung 983 DCT 960GB NVMe M.2 Enterprise SSD for Business".
More info:

Are you running on HDDs? The minimum allocation size is 64kb by
default here. You can control that via the parameter
bluestore_min_alloc_size during OSD creation.
64 kb times 8 million files is 512 GB which is the amount of usable
space you reported before running the test, so that seems to add up.
I have tried to create erasure pools for CephFS using the examples given
at
https://swamireddy.wordpress.com/2016/01/26/ceph-diff-between-erasure-and-replicated-pool-type/
but this is resulting in some weird behaviour. The only number in
common is that when creating the metadata store; is this
Hello,
I wanted to know if there are any max limitations on
- Max number of Ceph data nodes
- Max number of OSDs per data node
- Global max on number of OSDs
- Any limitations on the size of each drive managed by OSD?
- Any limitation on number of client nodes?
- Any limitation on maximum number

Hi,
I upgraded my test Ceph iSCSI gateways to
ceph-iscsi-3.0-6.g433bbaa.el7.noarch.
I'm trying to use the new parameter "cluster_client_name", which - to me
- sounds like I don't have to access the ceph cluster as "client.admin"
anymore. I created a "client.iscsi" user and watched what happene
I would like to use rbd image from replicated hdd pool in a libvirt/kvm
vm.
1. What is the best filesystem to use with rbd, just standaard xfs?
2. Is there a recommended tuning for lvm on how to put multiple rbd
images?

The issue we have is large leveldb's . do we have any setting to disable
compaction of leveldb on osd start?

Any help on this would be much appreciated as our prod is down since a day
and each osd restart is taking 4-5 hours.

We have maxed out the files per dir. CEPH is trying to do an online split
due to which osd's are crashing. We increased the split_multiple and
merge_threshold for now and are restarting osd's. Now on these restarts the
leveldb compaction is taking a long time. Below are some of the logs.

Hi!
In my ongoing quest to wrap my head around Ceph, I created a CephFS
(data and metadata pool with replicated size 3, 128 pgs each). When I
mount it on my test client, I see a usable space of ~500 GB, which I
guess is okay for the raw capacity of 1.6 TiB I have in my OSDs.
I run bonnie wit

Hi Erik,
For now I have everything on the hdd's and I have some pools on just
ssd's that require more speed. It looked to me the best way to start
simple. I do not seem to need the iops yet to change this setup.
However I am curious about what the kind of performance increase you
will get fr
