The 5.0 beta VM that before had 300 on average, went down to 210 with barrier=0 (I've tested with a grep in /proc/mounts and shows the "nobarrier" option).

I've done a "better than nothing" test: in my production server I've created 2 VM, storage in thin-lvm, 32GB, 2GB ram. One has 4.4, the other 5.0beta, default configuration (no updates, no config changes, no new packages installed, just bare metal installation and reboot) On average of 4 tests...

Since I've BBU, barrier=0 was never necessary, writeback cache took care of the performance drawback. I've now installed 4.4 on the same hardware, same fstab config, and I've fsync of 8800! So there is something badly broken in 5.0 beta about performance, at least with areca, or the measurement...

I've a new server where I've installed an Areca RAID controller 1883i, 4 x 1TB RAID10 WD Enterprise Gold and 2 x 2TB RAID1 WD Enterprise Gold. The controller has a "supercap" and Write Back cache enabled, raid has been initialized this night. With Proxmox 4 the same controller with 4x500GB...

Spice in Win10? As far as I know Win10 is not supported by Spice so far, and when I tried performance and responsiveness were terrible. How did you make it work?

So you mean that I can't create a 2 storage node with a 3rd cheap node just for proxmox quorum, as I did with drbd9 (that I have to abandon due to licensing changes)? What alternative (complexity and cost wise) do I have? People here just need the possibility to have redondant nodes/storage, HA...

There is 0.97.3-1 in the repo, but after upgrade the calculation is still wrong. Is there any command to run to make it "recalculate", or something further to do? I should have plenty of free space but is reported not, and I will be introubles if I will have to create some more VM or enlarge...

Ok, I've upgraded first the "control node", then rebooted. Then I upgraded the node with storage but no VM on it, and rebooted. Last I upgraded the node with storage where VM are run (primary), and rebooted. Everything went fine, fortunately. The only big problem is that still, with 2x800GB for...

I've a 3 node cluster (but only 2 node storage) with enterprise repo and drbdmanage 0.91-1, so I think I'd better upgrade now (also hoping 0.97.3-1 will fix some issues about calculated free space) since the license change and waiting to things to clarify (and in the future avoid the...

So the "few facts" also are: a) DRBD Manage is NOT free(dom) software anymore b) you can NOT trust Linbit about developing free software, the license can become proprietari in a snap c) is bettere not use DRBD if you use Proxmox, since you can't have support from proxmox and you have to pay 2...

Seems so, I've also noatime, i.e. my config is usually like that /dev/pve/data /var/lib/vz ext4 defaults,noatime,nobarrier 0 1 of course after changes in fstab you have to remount or better reboot :)

Try to mount the file system with "nobarrier" option, a bit more risky (search about the implications) but definetely your fsync numbers will increase a lot

I know, is the way I installed them :) But you stated "there is no guest-tool exe for win10, only for win7", I of course was referring to guest-agent (qemu-ga-x64.msi), so just now I see the confusion that has been made (I thought was the same thing). I will investigate further tomorrow since...

Argh, the wiki is not that clear about it, so I should remove them? How is that I've been able to have "QUEMU Guest Agent" and "QUEMU Guest Agent VSS Provider" running? I need to try to find how to uninstall them? Seems at least that shutdown is fine with them installed.

I reply to myself about the manual installation. I've found in a oVirt page the necessary steps, that are: run cmd as administrator, go in the directory where the unpacked files are, run "vdservice install" and then "net start vdservice". In services, you will have now "RHEV Spice Agent". Mouse...

Probably, because everywhere is stated that if you install guest-tools, should be included and installed!!! When has this been broken? I installed a test Win7 recently and AFAIR I had the same issue. In any case, I've dowloaded the file you pointed me, extracted the zip, doble clcked in vdagent...

Hi, I've a Kubuntu 16.04 vm and spice works fine (I've "Use tablet for pointer" Yes, "Qemu agent" Yes, Display "Spice (qlx)" and in the guest I've installed spice-vdagent). But when I try to set spice on Windows 10 pro (or even Win7), the mouse keeps being grabbed and is not precise/does not...

Just to notify you that I installed (bare metal) 4.2 without internet connection, had problems to identify the right eth0 port so I did some reboot before solving (AFAIR), and had the certificate FAR AWAY from current date/time (I recreated it with your instruction and now everything is ok)...

I don't understand you completely. I've 2x800GB SSD in each of the 2 storage node (3° node only for quorum). That is why VG is 1.4TB (I've not fully used the theorethical 1.6TB capacity) root@prox01:~# lvs LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert .drbdctrl_0...

That was my feeling too, but seems that Proxmox team just ignored me thinking that "drbd9 is broken", and they could be right, just we should understand if the "redundancy" adjustment should be made by drbd tools or by proxmox ones. In my situation, with redundancy 2, for instance I have: #...
