Hi Erich,
I raised one tracker for this https://tracker.ceph.com/issues/65607.
Currently I haven't figured out where was holding the 'dn->lock' in the
'lookup' request or somewhere else, since there is not debug log.
Hopefully we can get the debug logs, which we can push it further.
Thanks
Hi Alexey,
This looks a new issue for me. Please create a tracker for it and
provide the detail call trace there.
Thanks

They were my job for a year, so yes, I do. The published specs are accurate.
A QLC drive built from the same NAND as a TLC drive will have more capacity,
but less endurance. Depending on the model, you may wish to enable

Hello Anthony,
Do you have any data on the reliability of QLC NVMe drives? How old is
your deep archive cluster, how many NVMes it has, and how many did you
have to replace?

Strictly speaking, that isn’t necessarily true. Proprietary standards and the
like *can* enhance user experience in some cases. Making it intentionally
difficult to migrate
Vendor lock-in only benefits vendors. You’ll pay outrageously for support /
maint then your gear goes EOL and you’re trolling eBay for parts.
With Ceph you use commodity servers, you can swap 100% of the hardware without
taking downtime with servers and drives of your choice. And you get
A deep archive cluster benefits from NVMe too. You can use QLC up to 60TB in
size, 32 of those in one RU makes for a cluster that doesn’t take up the whole
DC.

If you are careful not to over estimate the performance, then you are ok.

Suggestion: Start with your requirements, vs the “ilities” of the storage
system.
By “ilities” I mean scalability, flexibility, distributability, durability,
manageability, and so on - any storage system can and will lay (at least some)
claim to those.

Hi Niklaus,
Lots of questions here but let me tray and get through some of them.
Personally unless a cluster is for deep archive then I would never suggest
configuring or deploying a cluster without Rocks DB and WAL on NVME.
There are a number of benefits to this in terms of performance and
Dear colleagues, hope that anybody can help us.

CephFS is installed also.
Yesterday we discovered that some of the applications stopped working.
Some additional information. Even though the pgs report unknown, directly
querying them seems like they are correctly up.
What could be causing this disconnect in reported pg states?

Hi,
We have recently upgraded one of our clusters from Quincy 17.2.6 to Reef
18.2.1, since then we have had 3 instances of our RGWs stop processing
requests. We have 3 hosts that run a single instance of RGW on each, and all 3
just seem to stop processing requests at the same time causing our
