Apologies, I should've said that from the beginning. The frontend network is 1gbit, the backend is 10gbit. The CPUs are at 20% at all times even though they are weak, the RAM on the cluster (3x replica as noted) is below 70%.

Hi, I have invested in SAMSUNG PM983 (MZ1LB960HAJQ-00007) x3 to run a fast pool on. However I am only getting 150mb/sec from these. The frontend network is 1gbit, the backend is 10gbit. The CPUs are at 20% at all times even though they are weak, the RAM on the cluster (3x replica) is below 70%...

I am quite sure you could passthrough a usb device through to docker.

I got this running with apcd in a docker container checking the UPS via the network, with a crontab script looking for the apcd created file. Simple setup.

Hi, I tracked this down to be the fault of my HP Z400. Worked fine with HPZ420s tho, so replaced 400s with 420s :)

They upgraded the telemetry server VM and then this error message popped up. A restart of the mgr daemon solves the issue.

I am running about 34gb for my 6tb without issues. There is a flag specifying how big the journal is, however i do all creation of new OSDs via the GUI...

Tried with lvcreate says disk is busy, so I am back to finding out exactly which command is run at /usr/share/perl5/PVE/API2/Ceph/OSD.pm: print "creating block.$type on '$d->{dev}\n"; -> print "creating block.$type on '$d->{dev}' with $cmd\n"; ...

I tried that, but I fear that if I create it wrong, it might overwrite the whole disk. Hence I was actually digging into the perl code to see what the actual command for "creating block.db on '/dev/nvme0n1'" is, so that I could add one more partition for OSD usage after the block.db partitions...

Alwin, thank you for the reply. I was looking for the actual commands to partition up my NVMe after I have added the RocksDB. The limitations of the disk are understood, and looking at the current graphs I have now there is a LONG way to go before I hit the IOPS bottleneck of 200k that these...

I finally got my fast NVMe enterprise drives (Samsung PM983) at last, added a few journals to it for smaller spinners and would like to use the remaining disk space as an OSD/Monitor db/maybe swap. Are there any guides on how to achieve this ? Tried to peak at promox tooling in the GUI to tap...

@mgiammarco - Could you please provide an URL to these drivers?

Hi, Am wondering if ceph has built iscsi for debian so we can use them on proxmox? I'm running iSCSI from a Windows VM right now and its not optimal I don't think, its got very low speeds. Thanks, A

With that said, 14.2.4 was released today fixing issues with ceph-volume in 14.2.3 so I do appreciate the lag between releases in the upstream and proxmox releases!

I keep refreshing to see this version popup as well, so here is an upbump! :)

The pool itself is what decides which OSDs to reside on and also the compression. No need to instruct the OSDs individually.

Install ceph, activate RGW (S3) and multisite sync with another ceph cluster is my plan..

Has there ever been a reason to "never support Docker" tho ? Is it licensing or what is the reason ?

Tokala, I just wanted to say thank you, that is truly awesome! :)

Actually, 30GB is enough for a journal, the 10% recommendation is just the "safe" recommendation even though it wastes ssd space..
