Hi, One of my 6 v5.3 nodes cluster crashed last week (due to motherboard failure). The other nodes fenced the crashed node and all involved Vms have successfully migrated to another node. I can see that the 4 Ceph OSDs of this node are marked as down and out. Dell support changed the...

Ok so I misunderstood, sorry for that. I can't believe anyone want to do kind of thing :)

Hi, Could you explain why not ? I have a VM (SQL Svr 2k16) with one Ceph 'OS' disk and a ZFS 'SQL Data' disk running without any kind of issues for months. ZFS disk is replicated every 2 hours. Everything works as expected. The only dirty thing is that I must power off VM if I want to migrate...

Hi, We are currently experiencing issues with Broadcom cards. (Dell R440) 5e:00.0 Ethernet controller: Broadcom Limited BCM57416 NetXtreme-E 10GBase-T RDMA Ethernet Controller (rev 01) 5e:00.1 Ethernet controller: Broadcom Limited BCM57416 NetXtreme-E 10GBase-T RDMA Ethernet Controller (rev...

Hi, Seems that there are new updates on pve-enterprise repository. Do they solve the issue ? Thanks

Thanks for your answer. My question would be : is there a need to settle iothread while only one disk require IOPS ? Antoine

Hi, Same issue for me here root@tco-prox-03:~# systemctl status pvesr.service ● pvesr.service - Proxmox VE replication runner Loaded: loaded (/lib/systemd/system/pvesr.service; static; vendor preset: enabled) Active: failed (Result: exit-code) since Mon 2018-10-29 00:04:09 CET; 27s ago...

Hi, I just built a new KVM virtual machine, I first decided to put only one vdisk with few partitions (on a RAID10 ZFS pool with fast SSD), one partition for OS and the other for datas (SQL Server databases). I'm wondering if instead of using only one vdisk it could be better to use 2 vdisks...

Caution : idle=poll is not compatible with hyperthreading (slow down performance) https://software.intel.com/en-us/forums/software-tuning-performance-optimization-platform-monitoring/topic/535130

Ok so another question : I plan to add 2 vdisk (on zfs pool), one for OS and the other for datas. Adding more than one vdisk on a scsi virtio controller affects IOPS ? iothread could not be used due to backup issue... What are your recommendations ? Thanks.

Hi, I plan to build same kind of VM Win2012R2 with 32 Gigs of RAM VM Disk on RAID-10 ZFS (4 SSD) SQL Server 2016 Any tricks to give me ?

Ok thanks!

Hi! I recently upgraded a 3 nodes cluster, I was about to add a new ceph pool and I saw a new checkbox option related to hyperconverged ceph tool : What is it ? Thanks!

grub with only idle=poll is enough to put CPU at its maximum speed.

I don't monit power consumption sorry. Just noticed that I tried all possibles values : processor.max_cstate=0 intel_idle.max_cstate=0 idle=poll processor.max_cstate=1 intel_idle.max_cstate=1 idle=poll processor.max_cstate=0 intel_idle.max_cstate=1 idle=poll processor.max_cstate=1...

Works as expected !! Thank you so much :)

Thanks I will. I keep you guys in touch :)

Hi, Seems that settle 'intel_pstate=disable' in /etc/default/grub is not working anymore. However, intel_idle.max_cstate=0 processor.max_cstate=1 permit cpus to work at higher frequency but turbo still active. In order to avoid sync issues inside vms, I'd prefer want my cpus working at constant...

Hi, From proxmox documentation : Maybe settle multiqueue for Windows guest OS is not enough

Thanks, that makes sense. I will investigate on my netgear switch stack
