didn't read every page, but this is looking great. Can't wait to see the next milestone release.

Trying to find out if any progress has been made in multi-cluster HA. Like the previous poster, I have multiple DCs. I have 10G at each side and <15ms latency between BUT I don't really love the idea of trying to cluster across that.

yes, stayed up super late last night to check the bios after hours. It's up-to-date and there are no knobs for memory. Bios is 'I20' which is HP's current listed max for this BL260cG5... What is curious is that this seems to be a throughput between the ram and the CPU. If I scale the threads...

No ECC options in the BIOS BIOS power savings is set to 'maximum performance' DIMMS are 6x 4GB DDR2 667 dmidecode: Handle 0x1100, DMI type 17, 23 bytes Memory Device Array Handle: 0x1000 Error Information Handle: Not Provided Total Width: 72 bits Data Width: 64...

1 pass should be more than enough to determine performance issues. I'm not seeing malfunctions from bad bits here. Took 2 hours 50 minutes for 1 pass on 24GB ECC ram. I think that's high but the only system I could compare it to has DD4, it took 44 minutes for 24GB ECC.

This is a bit of an extension of this thread: https://forum.proxmox.com/threads/kvm-performance-issues.42635/#post-204952 *but* My identification of the issue was misguided. What I've found is memory performance on the host is just 277MB/s. This is pulled from the sysbench --test=memory...

yeah, I'm seeing that. one of my other prox hosts gives 3465MB/s in KVM and 3922MB/s on the host. I'm only getting 267MB/s on LXC and the Host here, I think my LXC results before were not accurate. ECC Ram in this server so I suspect I have a bad chip and ECC is masking that with slow...

Is there any setting to isolate the LXC container from sharing the 'load' from the host in top/htop? Was a little shocked when looking at load of 1.5 in the container with nothing running until I figured out what was going on. Can make solving load issues in a container pretty difficult and...

No, but I found something peculiar. running `sysbench --test=memory run` in LXC I get 277.65MB/s in KVM I get 41.10MB/s I did the same tests with CPU and they are nearly identical. Is there something in KVM that would be limiting memory rates?

v5.1-41 as a cheap benchmark, I'm compiling asterisk on centos7 kvm cpu type = host, numa=on specs for KVM and LXC vm/container same In VM, this takes 25 Minutes, in LXC, this takes 7 Minutes. Any idea where to start to identify this performance gap? I'm actually running asterisk on...

I'm looking for a way to set CPU affinity in proxmox 5. Is this doable? I'm aware of this thread: https://forum.proxmox.com/threads/numa-config-option.21313/#post-108514 But I'm not wanting just NUMA awareness, I'm wanting to set certain vms to certain CPUs (and others to NOT those CPUs).

so, ceph w/ 3 monitors and 2 OSD hosting nodes (with 6 OSD per) or DRBD on the 2 main nodes? Maybe my logic needs a sanity check here, but DRBD w/ LVM on top *doesn't* need a quorum because proxmox will have quorum yes? There is no chance that data same-blocks will be written to by both prox...

got a good guide for a 3 node DRBD (2 mirror, 1 quorum) ?

I couldn't get 3.8 to work with prox...
