Hi, Ok, so I have enabled Jumbo Frames on the switch and set MTU to 9000 on the storage NIC's, but the file copy speed in Windows didn't improve.

Ok, so I have the "virtio-win-0.1.141.iso" ISO installed and both the Hard Disk drivers and Network Drivers are up to date. Qemu Agent is installed and running. I followed and applied all the settings (again) as per this link: https://pve.proxmox.com/wiki/Windows_10_guest_best_practices

Please explain, where is this setup?

The Windows guests run the Virtio driver - will confirm the version shortly. The disk copy didn't use network, so I am not sure if the VirtIO driver is applicable to the problem? QEMU Agent? Is that inside Windows?

Hi, We have a 3 node cluster with CEPH, using the following hardware: 3x Supermicro server with following features per server: 128GB RAM 3x 8TB SATA HDD 2x SSD drives (intel_ssdsc2ba400g4 - 400GB DC S3710) 2x 12 core CPU (Intel(R) Xeon(R) CPU E5-2650 v4 @ 2.20GHz Quad port 10Gbe Inter NIC 2x...

Hi Fabian, That doesn't seem to work:

Hi, I am trying to stop a CEPH OSD from the command line but it doesn't want to stop: root@virt2:~# ceph osd tree ID CLASS WEIGHT TYPE NAME STATUS REWEIGHT PRI-AFF -1 65.50461 root default -3 21.83487 host virt1 0 hdd 7.27829 osd.0 up 1.00000 1.00000...

I just had the same happen to me. The server rebooted as soon as we pulled the network cable out (had to swap them out for CAT 6E cables): Here's the log just before the reboot: Nov 7 12:14:34 virt1 pvedaemon[45503]: <root@pam> successful auth for user 'root@pam' Nov 7 12:14:54 virt1...

Did you see the commands I posted? I used your exact commands, but you just confirmed that due to the version change, the commands might have changed. One of the problems I am facing is that you can't stop the OSD from the command line, so I had to stop it from the Proxmox interface...

Hi, I have tried your way, but it fails as follow: So I manually stopped the OSD in the Proxmox interface and could flush it: Then later on I got the following error: So I manually deleted "/var/run/ceph/ceph-osd.0.asok" and tried again. Not sure if I should have? But at the end of...

Does anyone know, please?

How can you see which journal the osd uses?

Hi, How do I pin a CPU core to a CEPH OSD?

I am installing from an ISO hosted on the proxmox cluster, hosted on glusterfs, to a CEPH storage. The network is 10Gb and utilization is low. I find it hard to believe that installation is single threaded. The exact same installation, from a USB memory stick onto a Corei5 desktop PC was 2x faster.

Installing onto CEPH. You're saying 10Gbe is too slow??

I see the CEPH journal is 1GB. What is the correct procedure to make it bigger? Do I purely delete the 1G partition in fdisk, create a new one, and then specify what type? Or is there a preferred way to do it?

Hi, I wonder if someone can shed some light on this matter. The environment: 3x Supermicro server with following features per server: 128GB RAM 3x 8TB SATA HDD 2x SSD drives (intel_ssdsc2ba400g4 - 400GB DC S3710) 2x 12 core CPU (Intel(R) Xeon(R) CPU E5-2650 v4 @ 2.20GHz Quad port 10Gbe Inter...

Yes I read what he said. Still doesn't answer the question. With CEPH I now have 4 individual spinning disks in each machine. ZFS would add a bit of performance boost in most situations, so I am wondering if it would have added a performance boost in this case as well.

Has anyone done any comparisons of CEPH on top of ZFS? I am particularly interested to know if it would add any performance improvements?

If that's a one-way mirror, how would one recover from a disaster in such a case? i.e. if you have a cluster of 3 nodes in the main data center, and a backup server in a remote site, but the main data center is completely down (fire / theft / flood / etc), how would you safely copy / move the...
