Let's try to narrow it down.. I saw zfsutils in your listing. In order to exclude ZFS related issues, try a container with standard directory storage ( ext4, xfs). Inside container run apt install stress stress --vm-bytes $(awk '/MemFree/{printf "%d\n", $2 * 0.9;}' < /proc/meminfo)k...

I wanted to test the efficiency of Ipfilter-net for container. Inside the container, after running the following command ( from https://sandilands.info/sgordon/address-spoofing-with-iptables-in-linux), spoofing the ip, all output network activity is blocked ( ping etc). iptables -t nat -A...

Since I am coming from php world ( Xdebug remote with ssh tunneling via PhpStorm), it would be best to ask via example. I want to debug btrfs snapshot rollback feature. -Setup a breakpoint in function volume_snapshot_rollback from PVE/Storage/BTRFSPlugin.pm...

Please ignore... It was false alarm, I didn't enable btrfs quota btrfs quota enable /unt

Comparing proxmox lxc-pve with ubuntu lxd, I considered the potential incompatibility of newer btrfs-progs with LXC packages. It’s not the case … btrfs-progs 4.7.3-1 plays well with lxc 2.0.7, so even 4.6.1-1~bpo8+1 should. PROXMOX 4.4.13 btrfs-progs 4.6.1-1~bpo8+1 lxc-pve...

USE CASE 2 /var/log/apache2/error.log [Fri Mar 31 08:36:29.521373 2017] [core:error] [pid 925:tid 139909948708608] (13)Permission denied: [client XXXXXXXX:64636] AH00035: access to /btrfs/index.html denied (filesystem path '/var/www/html/btrfs/index.html') because search permissions are...

I’ve done some 2 experiments, in order to narrow down the issue USE CASE 1 Debian Container with rootfs local directory ext4 and mount point btrfs. root@pdevel:~# cat /etc/pve/lxc/104.conf ... mp0: bunt2:104/vm-104-disk-2.subvol,mp=/var/www/html/btrfs,size=1G rootfs...

With Ubuntu lxc on btrfs I don't get denied, but with Debian lxc btrfs i got the following. root@pdevel:/etc/pve/lxc# dmesg | grep DENIED [50081.659090] audit: type=1400 audit(1490913001.247:7): apparmor="DENIED" operation="mount" info="failed type match" error=-13...

There's already a post regarding ZFS on Linux licensing https://forum.proxmox.com/threads/proxmox-btrfs-support-roadmap-as-fallback-for-possible-licensing-issues-zfs-on-linux.32561/ Let's keep this one in technical area. Thanks!

This is lucky strike patch, when I get serious, I post it to mail devel. Don't waste your time, you should commit directly. Rebooted the proxmox node, replicate the errors, I don't have denied message. root@pdevel:~# dmesg | grep apparmor [ 5.125309] audit: type=1400...

First of all, kudos to Wolfgang Bumiller for the “hot” summer btrfs patches. It surpassed my expectations, it really works, except several issues, perfectly normal for an experimental phase. Related proxmox forum posts...

There's a confusion here... The Debian/Proxmox OS installation is done on ext4/xfs partitions mdadm based. I prefer this setup also with ZFS, to avoid other non standard installation issues. Btrfs is used on different partitions/disks Your prediction reminds my of a BTRFS benchmark from 2012...

I don’t understand why do you artificial link your mdadm request to Btrfs. It makes no sense to advance into such dispute. I clearly expressed my opinion regarding Btrfs. Regarding mdadm, I always install Proxmox on top of existing Debian...

Googling “btrfs performance” or stability returns a lot of “false friend” results, due to obsolete benchmarks on kernel 2.x, 3.x . Things has changed a lot with the newest kernels 4.x. The best thing is to try it yourself . Proxmox includes a recent version of btrfs-progs 4.6.1-1~bpo8+1. I...

Fixed with dpkg -i --force-overwrite /var/cache/apt/archives/libcpg4_1.4.6-1.1_amd64.deb dpkg -i --force-overwrite /var/cache/apt/archives/libsam4_1.4.6-1.1_amd64.deb apt-get -f install

I understand now, but the damage was done, I have followed the wrong instruction for Debian Strech pve devel on Jessie. Trying... apt-get -f install apt-get update dpkg --configure -a apt-get clean But I am stuck with... apt dist-upgrade Reading package lists... Done Building dependency...

It seems that i cannot get rid of The following packages have unmet dependencies: libcpg-dev : Depends: libcpg4 (= 1.4.6-1.1) but it is not installed libsam-dev : Depends: libsam4 (= 1.4.6-1.1) but it is not installed Any quick tip or i have to dig myself depper?

Thanks for the solution. I want to test btrfs storage integration status https://www.mail-archive.com/search?a=1&l=pve-devel@pve.proxmox.com&haswords=Btrfs&x=13&y=16&from=&subject=&datewithin=1d&date=&notwords=&o=relevance So, stable-4 is the needed branch. On the other hand, it's ok to have...

Proxmox VE 5.x family - based on the Debian Stretch - already looks like a hit. Can you “stretch” the release roadmap to include BTRFS storage, at least as technology preview ? Wolfgang Bumiller progress seems to be significant...
