As i know LACP is supported only on same switch, but i need to use different switches to get failover. Can you explain, what you mean "In the worst case your cluster is crashing and your lose data." On one switch - yes, if switch will be lost - cluster will be lost, therefore i need two switches...

Hi good people. I have question about ceph deployment. My hardware configuration is: x4 servers with dual head 40gbps mellanox NIC x2 mellanox 40gbps switches Can i bond NIC's and use this NIC's as main network for ceph, cluster and virtual machines access? I made such deployment using...

Of cource no. =) Actuallu I have asked a question about building so project. But if i will succesfull in building such cluster i will share the result.

Hi good people. We have a bunch of hardware (a little old) - 4x servers with dual xeon E5 2667-V3, 2 LSI SAS 6160 switches, and one Supermicro JBOD SC837 (12x SSD 2TB, 18x HDD 8TB). Each server has 40 Gbps ethernet, and we have 2x mellanox 40Gbps switches. Nice hardware. Old sysadmin planned to...

Yep, reboot fixed for me too - after reboot i have deleted all manualy using zfs destroy pool1/subvol_bla_bla_bla. It's definetly not good for production server such bugs.

Same here. I powered server off for maintenance at 19 march, and after that i started it. Today one of the stupid support guys killed mysql in one of the lxc container. I tryed to recover it from backup (nfs backup), but got same error: TASK ERROR: zfs error: cannot destroy...

Made some performance tests with 2 and 4 cores using kvm64 and host cpu type. Very strange, but in more than 10 SuperPi and Novabench tests, kvm64 got better performance than host cpu.

Hi good people. We have deployed proxmox 4 on new supermicro server and stucked with one problem. In Windows Server 2012 R2 CPU clock is only 1GHz, but real CPU Clock is 2,3GHz. The virtual machine has standard configuration, cpu type kvm64 default, but all monitoring programs inside virtual...

Hi good people. I have a question about some BIOS tuning practices for get maximum from virtualization server. We got new Supermicro servers, and i need advice about settings to make proxmox run best on this servers. Last 3 years i have worked exclusively with HP Proliant rack servers, and are...

I know about Thecus Zub NAS C10GTR nothing, but i really suggest using Intel brandad NICs in real production - they are very reliable and have good performance. Intel X540 T or T2 are very good choise, but are not cheap. You can use also some Broadcom 10Gbps fiberoptic NICs – the cost will be...

Re: Proxmox 4 "pve" not found after first start. Ha! Thx wolfgang. Got to work it. But it's strange, i have tryed to do similar thing - in grub boot menu i have pressed "e" and added after "ro quiet" parameter "rootdelay=5" to kernel, than used F10 to boot this line and it told me that...

Hi good people. My customer got two new servers for virtualization. I have decidet to use proxmox 4 with zfs local sotrage and ssd cache for zil and l2arc. I think the proxmox is best small/medium solution for standalove server or small cluster virtuaization. I have already in production 4...
