Hi list,
Having finished our adventures with Infernalis we're now finally running
Jewel (10.2.11) on all Ceph nodes. Woohoo!
However, there's still KVM production boxes with block-rbd.so being
linked to librados 0.94.10 which is Hammer.
Current relevant status parts:

Hi,
We are planning to build NAS solution which will be primarily used via NFS
and CIFS and workloads ranging from various archival application to more
“real-time processing”. The NAS will not be used as a block storage for
virtual machines, so the access really will always be file oriented.

Hi!
ZFS won't play nice on ceph. Best would be to mount CephFS directly with
the ceph-fuse driver on the endpoint.
If you definitely want to put a storage gateway between the data and the
compute nodes, then go with nfs-ganesha which can export CephFS directly
without local ("proxy") mount.
I had
We've done ZFS on RBD in a VM, exported via NFS, for a couple years.
It's very stable and if your use-case permits you can set zfs
sync=disabled to get very fast write performance that's tough to beat.
But if you're building something new today and have *only* the NAS
use-case then it would make b
Hi Dan,
ZFS without sync would be very much identical to ext2/ext4 without journals
or XFS with barriers disabled.
The ARC cache in ZFS is awesome but disbaling sync on ZFS is a very high
risk (using ext4 with kvm-mode unsafe would be similar I think).
Also, ZFS only works as expected with schedu

Hi Kevin,
I should have also said, that we are internally inclined towards the
"monster VM" approach due to seemingly simpler architecture (data
distribution on block layer rather than on file system layer). So my
original question is more about comparing the two approaches (distribution
on block
My 2 cents would be depends how H/A you need.
Going with the monster VM you have a single point of failure and a single
point of network congestion.
If you go the CephFS route you remove that single point of failure if you
mount to clients directly. And also can remove that single point of networ
Some kind of single point will always be there I guess. Because even if we
go with the distributed filesystem, it will be mounted to the access VM and
this access VM will be providing NFS/CIFS protocol access. So this machine

Does your use case mean you need something like nfs/cifs and can’t use
CephFS mount directly?
Has been quite a few advances in that area with quotas and user management
in recent versions.
But obviously all depends on your use case at client end.

Yes, the access VM layer is there because of multi-tenancy - we need to
provide parts of the storage into different private environments (can be
potentially on private IP addresses). And we need both - NFS as well as
CIFS.

Hi,
Is it identical?
In the places we use sync=disabled (e.g. analysis scratch areas),
we're totally content with losing last x seconds/minutes of writes,
and understood that on-disk consistency is not impacted.

I have just setup another cluster to check on completely different hardware

And getting inconsistent PG’s flagged after an auto deep scrub which can be
fixed by just running another deep-scrub.

Thanks does look like it ticks all the boxes.
As it’s been merged I’ll hold off till the next release than rebuilding
from source. As from what it seems it won’t cause an issue outside of just
re running the deep-scrub manually which is what the fix is basically doing

Hi,
I have been reading up on this a bit, and found one particularly useful mailing
list thread [1].
The fact that there is such a large jump when your DB fits into 3 levels (30GB)
vs 4 levels (300GB) makes it hard to choose SSDs of an appropriate size. My
workload is all RBD, so objects shoul
