What test are you running to get those "client throughput" results? Throughput from where to where? What type of drives? I'm copying from a NAS to a Windows client over a 10Gbps network so 1GB/s is all I'm hoping for, but not achieving. The first 5GB are copied at the expected speed but then it...

Further testing with this new cluster. When I copy 15GB folder containing three ISO files from our Synology 10Gbps NAS to my Windows VM desktop the throughput starts out around 800 to 900 MB/s but then hits a wall and drops to about 20MB/s. This is a 5 node cluster with 18 8TB SATA drives per...

Been running some MS Diskspd tests on a Windows 10 VM with this setup. Not as good as hoped for. With write back 26.8 MiB/s read, 11.5 MiB/s write 8k 228.6 MiB/s read, 97.7 MiB/s write 256k Without write back 18.9 MiB/s read, 8.1 MiB/s write 8k 167 MiB/s read, 71.4 MiB/s write 256k rados -p...

Thanks Alwin. I see usage listed as LVM for my NVMe drive. I used the GUI to create my OSDs and divided the 3.54TB NVMe by 16 to match the number of OSDs. Therefore I specified 220GB of capacity for each OSD. How would this 220GB be divided between the DB and WAL? I did not specify the -db_size...

I've installed Proxmox/CEPH 6.0 on 5 Dell R740XD servers. Each has (16) 8TB spinners and 1 Supermicro NVMe card with a 4TB Samsung NVMe drive. During the OSD creation I allocated 1/16 of the NVMe to the DB of each 8TB OSD. After creating the 80 OSDs I see a CEPH usage of 3%, 17.5TB of 599TB...

Anything new on this issue? I've been manually running backups without an issue since giving up on the scheduled backups.

Seems like I am experiencing this issue too. I had a new Widows Server 2016 VM go corrupt a few weeks back for no apparent reason. Since it was new I just spun up another. However, over this past weekend I had a Windows server qcow file vanish from the NFS storage!? I've recently started using...

Understood Rock. Here is my take on what's happening. Not sure if this will make this any clearer to Alwin?? From https://pve.proxmox.com/pve-docs/chapter-pveceph.html#_ceph_bluestore “pveceph createosd /dev/sd[X] Note In order to select a disk in the GUI, to be more failsafe, the disk...

Rock, from reading Alwin's reply on Bugzilla I see he is saying only the bluestore_block_db_size value will be used when both the db and WAL are on the same device and that only one partition will be created for both using the size specified. Are you wanting to specify the WAL separately only to...

Hi vmanz, Thanks for you reply. Yes, I'm familiar with these devices. I've converted my VMware cluster at home to Proxmox over the last 2 weeks. The requirement for a serial port on a node is for an RF home automation device. Not really worth the trouble or cost of procuring a network serial...

Is there any way to do this without rebooting the VM? I'd like to migrate a production VM to another node so I can reboot the first node after upgrading Proxmox. Proxmox won't migrate the VM due to the associated serial port and I can't remove it without rebooting the VM. Kind of painted into a...
