This normally means you have some form of partition data on the RBD disk.
If you use -vvv on the pv command it should show you the reason, but yes redhat
solutions require an active support subscription.

Hello Sailaja,
Do you still have this problem?
Have you checked the crush rule for your pools to see if the data
distribution rule is met?

A quick google shows this:
You need to change your /etc/lvm/lvm.conf device name filter to include it. May
be that your LVM filter is not allowing rbdX type disks to be used.

I think it is, I already changed the lvm.conf with:

But this is still out commented

Hi Joachim,
Thanks for your response. I am very new to ceph. I am not sure about the
crush rule. I just followed the cephadm deployment instructions and did not
make any changes. It looks like the radosgw service is not running properly.
When I run the command,

The 14.8 ms number is the average latency coming from the OSDs, so no need
to divide the number by anything. What is the size of your writes? At 40

Generally bdev-new-db performs no migration, RocksDB might eventually do
that but no guarantee it moves everything.
One should use bluefs-bdev-migrate to do actual migration.
And I think that's the root cause for the above ticket.
No, I don't think so. But you can try again after applying
bluefs-bdev-migrate

Hi all!
I export the rbd image use the export v2 format and without it.
The difference is the export v2 format image is more smaller than the image
which do not use export v2 format.
Can any body tell me why they are size is difference so huge?
Thanks very much!

Hi,
is there a way to synchronize a specific bucket by Ceph across the available
datacenters?
I've just found multi site setup but that one sync the complete cluster, which
is equal to failover solution.
For me just 1 bucket.
Thank you
