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

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
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.

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.

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

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?

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

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
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
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.
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".
