I'm just guessing, but because your read performance is slow as well,
you may multiple issues going on. The Intel 530 being slow at O_DSYNC

Hi Shane,
We (Bloomberg) have many large clusters and we currently use Ubuntu. We
have just recently upgraded to Trusty (14.04). Our new super object store
that we're building out is using Trusty but we may switch to RHEL because
of other departments joining in - final decision has not been made.
The journal should be a raw partition and should not have any filesystem on it.
Inside your /var/lib/ceph/osd/ceph-# you should make symlink to the
journal partition that you are going to use for that osd.

Neither of these are DC level SSDs of course, though the HyperX at least

Hi,
I've just noticed an odd behaviour with the btrfs OSDs. We monitor the

the monitoring system collects the total amount of sector written and

this is with Firefly 0.80.9 and the btrfs OSDs are running on kernel

total and 2 of them are using

How do I prepare the Journal prior to the prepare/activate stages of the
