red fuse.ceph defaults 0 0
Am I passing the argument correctly? And should I include the m argument as
well?
Thank you for your input.

acceptable?
3. Is it possible to scale down the number of pg’s ?
Thank you for your input.

>From what I understand about Ceph architecture you would be causing a
bottleneck for your ceph traffic. Ceph advantage is the potential
concurrency of the traffic and the decentralization of the client facing
interfaces increasing scale-out capabilities.
Can you give a bit more details about your
operation while the cluster isnt as busy.

Dan, I think your interpretation is indeed correct.
The documentation on this page looks to be saying this.

Increasing the number of placement groups reduces the variance in per-OSD load
across your cluster. We recommend approximate
Hi Everyone,
I am just wondering if any of you are running a ceph cluster with an iSCSI
target front end? I know this isn’t available out of the box, unfortunately in
one particular use case we are looking at providing iSCSI access and it's a
necessity. I am liking the idea of having rbd device

As for the IOPS, it would be a total cluster IO throughput estimate based
on an application that would be reading/writing to more than 60 rbd
volumes.

Hi All,
I am curious to know what is the largest known ceph production deployment?
I am looking for information in regards to:
* number of nodes
* number of OSDs
* total capacity
And if available details in regards to IOPS, types of disks, types of network
interfaces, switches and
Anyone know why this happens? What datastore fills up specifically?
