Joe,
sorry, I should have been clearer. The incompatible rbd features are
exclusive-lock, journaling, object-map and such.
The info comes from here:

Again the doc shows and we have used layering only as a feature for
iSCSI
Further down it gives you specific settings for the luns/images
In our case we let vmware/veeam snapshot and make copies of our VMs
There is a new Beta of SES that bypasses the iscsi gateways for Windows
servers
Here is a link for iSCSI/RBD implementation guide from SUSE for this year for
vmware (Hyper-v should be similar)
https://www.suse.com/media/guide/suse-enterprise-storage-implementation-guide-for-vmware-esxi-guide.pdf
We've been running rbd/iscsi for 4 years
Thanks Joe

Well, it sounds like the pdcache setting may not be possible for SSD's, which
is the first I've ever heard of this.
I actually just checked another system that I forgot was behind a 3108
controller with SSD's (not ceph, so wasn't considering it).
It looks like I ran into the same issue during

Nope, never did this. So there are two clusters running with the same
fsid :-)

Hi,
Last night I've spend a couple of hours debugging a issue where OSDs
would be marked as 'up', but then PGs stayed in the 'peering' state.
Looking through the admin socket I saw these OSDs were in the 'booting'
state.
Looking at the OSDMap I saw this:
osd.3 up in weight 1 up_from 26

This looks like issue: https://tracker.ceph.com/issues/42338
Do you use snapshots on this fs?

In theory it should be possible to do this (to change the Block SSD Write Disk
Cache Change = Yes setting)
1. Run MegaSCU -adpsettings -write -f mfc.ini -a0
2. Edit the mfc.ini file, setting "blockSSDWriteCacheChange" to 0 instead of
1.
3. Run MegaSCU -adpsettings -read -f mfc.ini -a0

Yes, that is my intermediate solution. But I cannot tell my trainees
next week that they have to
Hi Robert,
The host where the browser is on needs to be able to reach the Grafana instance
by `ceph01` hostname (maybe add an entry to /etc/hosts?).
There was a fix [1] that allows custom Grafana URL (so the cephadm doesn't
override it).
It's backported, maybe the version you are using doesn't
Hi，
Yep I think the header is the cause too. I modify the configuration but it
still gets 403 error,
which I consider that the header may not be transferred to the backends.
But if I set it to level 4 rather than level 7, nginx works well.

I think you might need to set some headers. Here is what we use
(connecting to Swift, but should be generally applicable). We are
running nginx and swift (swift proxy server) on the same host. but again
maybe some useful ideas for you to try (below).
Note that we explicitly stop nginx writing

We don't use snapshots, but *maybe* sometime
Hi all,
We had a stuck mds ops this morning on a 14.2.11 cephfs cluster. I
tried to ls the path from another client and that blocked.
The ops were like this:
# egrep 'desc|flag|age' ops.txt
"description": "client_request(client.1212755100:37475
lookup #0x1003e229d38/analytics-logs

Yes, I should have mentioned that. No effect, though.
