Hi everyone,
few days ago I reduced the number og PGs on a small pool. The cluster
runs 14.2.2, was upgraded from jewel to 14.2.1 and the to 14.2.2. I did
a ceph-bluestore-tool repair on all OSDs to update statistics.
Today I got a scrub error reporting:
4.3 scrub : stat mismatch, got 68/68
Hi
Yesterday one of our customers asked us a strange request. He asked us to use
SAN as the Ceph storage space to add the SAN storages it currently has to the
cluster and reduce other disk purchase costs.
Anybody know can we do this or not?! And if this is possible how we should
start to arch

It's certainly possible. It makes things a little more complex though. Some
questions you may want to consider during the design..
- Is the customer aware this won't preserve any data on the luns they are
hoping to reuse.
- Is the plan to eventually replace the SAN with JBOD, in the same systems?

Just my quick two cents here.
Technically this is possible which doesn't mean it's a good idea. I

they'll really save a lot and adding the latency etc on top not sure
this is what they're really looking for.
Just for testing and

In a past life I had a bunch of SAN gear dumped in my lap, it was spec’d by
someone else misintepreting vague specs. It was SAN gear with an AoE driver.
I wasn’t using Ceph, but sending it back and getting a proper solution wasn’t
an option. Ended up using SAN gear as a NAS with a single clie
After thinking about this more, you may also consider just adding the SAN
in as a different device class(es). I wouldn't be scared of doing it, but
you will want to paint a picture of this transitional environment, the end
goal, and any steps the customer will need to take to get there. Also,
