Another one, I think this one's better. I also put some comments. Any feedback is welcome.

The script sums used memory and cache/buffer memory, if this total goes beyond a threshold, it ask the system to drop cache pages. Furthermore, if the system started to swap while there is available memory, it flush the swap back to memory. I know, this is an ugly solution, but the time the...

So, after a lot search on the web I "hack a patch" to solve my problem. According to what I learned, every system has a cached-page feature which it uses to cache read files into unused memory areas. If this files are modified the system mark this areas as dirty and issue a command to write the...

While watching the backup ( I used vzdump 111 --node asgard --mode stop --compress gzip --remove 0 --storage local and watch -n 1 free -h), I discovered that during the backup used RAM never pass 4GB, while free RAM decreases and buff/cache increases up to 20GB and then system start swapping. I...

Your right, now I understand that, thanks.

Is it, possible to have an Proxmox ISO installer with last ZFS stable package?

Ok, here is a thing, I read that one must do a zpool export before upgrading zfs, I tried the command but got device busy. However using zpool history I saw an export done at some point. How can I run zpool export without getting a device busy error.

Also yes. Right now, I reinstalled Proxmox and the problem disappeared, I think the problem is related with a package upgrade. Since I installed the ISO Proxmox VE 5.1 ISO Installer (3rd ISO release) which have Kernel 4.13.3 and ZFS 0.7.2 and there is an upgrade for both, maybe I have to take...

Thanks for the response @mbaldini, yes every time I changed anything on /etc/modprobe.d/zfs.conf I did update-initramfs -u && reboot.

@Klaus Steinberger, thanks for your quick response and for helping me, yes I did: I added this options zfs zfs_arc_max=2147483648 to /etc/modprobe.d/zfs.conf using nano and then did update-initramfs -u && reboot. Also 2147483648=2G which is what I have right now. I tried with 20G, 8G, 4G, 2G...

This is my zfs setup # grep -H '' /sys/module/zfs/parameters/* /sys/module/zfs/parameters/dbuf_cache_hiwater_pct:10 /sys/module/zfs/parameters/dbuf_cache_lowater_pct:10 /sys/module/zfs/parameters/dbuf_cache_max_bytes:67108864 /sys/module/zfs/parameters/dbuf_cache_max_shift:5...

@Klaus Steinberger I follow your advice and set zfs zfs_arc_max=8589934592 rebooted and did the backup again without staring any VM or anything else, yet the same happend, I tried backing up a Windows KVM and a Linux KVM, same thing. Proxmox started to swap after 55% completeness, I'm clueless...

Ok this is crazy I just set vm.swappiness=90 (just to for testing) and my node ignore it I did it like this sysctl -w vm.swappiness=90 And like by setting vm.swappiness=90 on /etc/sysctl.conf and then rebooting. Both ways are ignored. Also, my node keeps swapping every time a do a backup and...

Hello, my name is Juan Carlos and this is my first time writing into this mailing list. I'm testing Proxmox using an ASUS P6T with 24GB RAM. Currently I have 4KVM using up to 12GB, which means I have 12GB free for ZFS, yet every time I do a VM backup, OS installation or any other workload...

2 KVM NethServer 7.4.1708 with 2GiB each one 2 KVM Win2012R2 with 4GiB each one No CT at the moment Proxmox node has 16 GiB Right now I have 7.26 GiB RAM used and 6.71 GiB in KSM sharing

Hello to the community, I'm trying to understand this two parameters that appear on the Web Interface Summary tab on each node. I'm posting this image show both parameters. As you can see my node RAM has used 4.65 GiB and ksmtunned service has consolidated 6.91 GiB. I thought that RAM usage...

It turns out that Centos 7 template it's fine. I'm trying to use Nethserver 7.4 on a CT and I thought the problems I'm having were related to the template, it seems to be with CT Network Devices, every time I start nethserver CT my network devices are renamed, check this log output: dmesg -wH...

Also I noticed this on system logs: # dmesg | grep -i error [ 0.605236] RAS: Correctable Errors collector initialized. [ 1.007396] ACPI Error: [DSSP] Namespace lookup failure, AE_NOT_FOUND (20170531/psargs-364) [ 1.007422] ACPI Error: Method parse/execution failed...

I'm trying to use Nethserver 7.4 in several containers for services like proxy, chat, VoIP, Mail, etc. Installing Nethserver in a KVM is pretty straightforward, but doing the same in a CT has some caveats. This is how I did it: Create CT ssh-public-keys must be a file with a ssh-rsa ...

Hello, could you please tell me if centos-7-default_20171212_amd64.tar.xz LXC template is based on Centos 7 Minimal ISO?
