Hi,
while googles leveldb was too slow for facebook they created rocksdb

Hi,
we have a setup of 4 Servers running ceph and radosgw. We use it as an internal

The cluster has been running smoothly for quite a while, but we are currently
experiencing issues with the radosgw. For some files the
I can recommend zabbix for it, I use it myself.
You just install zabbix agent on OSD node - it will automatically
discover mounted file systems and report usage on those(osd mounts as
well), nice GUI available if needed.
Sure, you need to set up zabbix server before, but it is easy and worth it!

I am working with a small test cluster, but the problems described
here will remain in production. I have an external fiber channel storage
array and have exported 2 3TB disks (just as JBODs). I can use
ceph-deploy to create an OSD for each of these disks on a node named
Vashti. So far ever

Thanks. I may have to go this route, but it seems awfully fragile. One

all disks are visible to all nodes, any one of them could mount

Hey,
What number do you have for a replication factor? As for three, 1.5k
IOPS may be a little bit high for 36 disks, and your OSD ids looks a bit
suspicious - there should not be 60+ OSDs based on calculation from
numbers below.

You will see roughly twice the throughput unless you are using btrfs

Hi all,
I'd like to use Ceph to solve two problems at my company: to be an S3 mock
for testing our application, and for sharing test artifacts in a
peer-to-peer fashion between developers.
We currently store immutable binary blobs ranging from a few kB to several
hundred MB in S3, which means bot
