Isaiah,
I'm trying to understand your requirements for a CephFS Active-Active setup.
What do you want to achieve with a CephFS Active-Active setup ?
Once you list the exact requirements, we can discuss further on how to
achieve them.
There's also something called *CephFS Snapshot Mirroring*:

Hi,
The cache was gone, optimize is proceed. This is not enterprise device, you
should never use it with Ceph 🙂

Hello!
I'd like to create a CephFS subvol, with these command: ceph fs
subvolume create cephfs_ssd subvol_1
I got this error: Error EINVAL: invalid value specified for
ceph.dir.subvolume
If I use another cephfs volume, there were no error reported.
What did I wrong?
Best regards,

Hi Ramin,
Thanks for your response. Can you explain it a bit more? How is the object
locator supposed to fix this problem? And do you have any idea of the root
cause?
Thank you

HI Pavin,
Thanks for the reply. I'm a bit at a loss honestly as this worked
perfectly without any issue up until the rebalance of the cluster.
Orchestrator is great. Aside from this (which I suspect is not
orchestrator related), I haven't had any issues.
In terms of logs, I'm not sure where t

Hi Ceph users,
I have a running cluster in octopus 15.2.12. I found an object in one of my
S3 buckets that does not exist in the bucket list but I can download it
with any client. I also tried to get bucket index data by ```radosgw-admin
bi list --bucket MYBUCKET --object MYOBJECT``` and it return
Quick update:
- I followed documentation, and ran the following:
# ceph dashboard set-rgw-credentials
Error EINVAL: No RGW credentials found, please consult the documentation on
how to enable RGW for the dashboard.
- I see dashboard credentials configured (all this was working fine before):
I built a net-new Quincy cluster (17.2.5) using ceph orch as follows:
2x mgrs
4x rgw
5x mon

coming days.
I migrated all data from my legacy nautilus cluster (via rbd-mirror, rclone

I do not have *direct* experience with that model but can share some
speculations:
That is a *consumer* model, known as “client” in the SSD industry. It’s also
QLC. It’s optimized for PB/$.
I suspect that at least one of several things is going on.

Hi,
That's exactly what I meant. I did try to activate but it fails and the problem
is due to bluestore label gone after reboot, which in the end caused the
activation fail and /var/lib/ceph/osd/ceph-$osd​ empty
Upgrading from Pacific to Quincy solved the problem for me.
