  1. Request: Optional monthly backups

    As an alternative I create daily backups and keep monthly backups using a hard link As a cronjob the following looks for files newer than 1 day and generates a hardlink with a monthly_ prefix 0 15 1 * * cd /backup/proxmox/dump; find * -mtime -1 -type f -exec ln {} monthly_{} \;
  2. What's about ceph luminous 12.2.7?

    Regarding release on production repositories Edit: I switched to the ``test`` release channel, but it would be nice to have it on the release channel soon
  3. Real ulimit value for lxc containers

    I guess it should be: lxc.prlimit.nofile: 65536 I have not tried it yet Edit: Corrected config setting. New ulimit can be checked with root@ct ~ # ulimit -Hn
  4. Suggestion: Add lrzip to Backup compression options

    vzdump could be extended to include zstd als compress option and issue an error if zstd is not installed. Implementation is similar to 'pigz'.
  5. Suggestion: Add lrzip to Backup compression options

    +1 Zstd is now available in debian stretch and supports multithreaded compression. I'm already using it for personal disk backups with >300MB/s compression speeds on consumer hardware.
  6. Proxmox 3.x IP hot/cold failover for static site

    It is a good start. Keepalived offers 2 important features: - Floating IP with VRRP for High Availability - Load Balancing on layer 3 or 4 I use floating IP and Nginx for load-balancing and SSL and HTTP2 termination. I highly recommend using gratuitous ARP with keepalived. A switch reboot could...
  7. Proxmox 3.x IP hot/cold failover for static site

    Both hosts work independently. You could use keepalived as a loadbalancer. Basic setup: 2x keepalived VMs which share a single and load-balance traffic to nodes In my case I use 2x Nginx VMs as proxy load-balancer with 2x floating IP and DNS load balancing. If one host is down, the second host...
  8. Proxmox 3.x IP hot/cold failover for static site

    Hi, i use keepalived to float a single IP between VMs. You can also add additional checks for your server or similar. Regards, Patrick
  9. ZFS and encryption

    It has been merged today! https://github.com/zfsonlinux/zfs/pull/5769
  10. Real ulimit value for lxc containers

    Thanks Wolfgang! I was not aware it is already in Proxmox 5.0. A wiki update would be much appreciated: https://pve.proxmox.com/wiki/Unprivileged_LXC_containers I'm still on Proxmox 4. As a workaround I'm using lxc.hook.pre-start and prlimit on parent-parent-pid (=> lxc-start)...
  11. Real ulimit value for lxc containers

    Hi, I'm also trying to raise ulimits in LXC. Unfortunately ulimits are not passed from pvedaemon/pveproxy to containers. pvedaemon and pveproxy raised to 256k open files. As well as nofile in /etc/security/limits.conf # cat /etc/systemd/system/pvedaemon.service.d/nofiles.conf [Service]...
  12. Proxmox VE 4.4 released!

    Safari websockets require a valid ssl certificate or added to keychain (always trust checkbox). See: https://github.com/novnc/websockify/wiki/Encrypted-Connections
  13. USB sticks vs SSD and DR

    I also considered ZFS RAID-1 on USB flash drives, but decided to use small SSDs for reliability. In case you run ceph mon and/or mds on the same host, I would also recommend SSDs. Are there any reliable USB flash drives?
  14. [SOLVED] Deb.7 Container wont run his init.d

    Reminds me of an openvz upstart udev problem. Some migrated containers took 5 minutes to start. inittab was blocked by udev. Unfortunately openvz enforces upstart instead of sysvinit in newer debian 7 templates. There should be a file "/etc/apt/preferences.d/parallels" that prevents sysvinit...
  15. Increased wait IO on Proxmox 4 with deadline scheduler

    echo noop > /sys/block/sdX/queue/scheduler and verify with cat /sys/block/sdX/queue/scheduler [noop] deadline cfq I use udev rules to set different attributes for block devices
  16. Increased wait IO on Proxmox 4 with deadline scheduler

    Did you try noop scheduler? Despite increase in IO wait, application latency dropped. I'm fairly happy with LXC and ZFS on Proxmox 4
  17. Unable to see Infiniband interfaces in Proxmox?

    @spirit is it possible to use EoIB with a linux bridge and LXC? Do you have any benchmarks for EoIB?
  18. Increased wait IO on Proxmox 4 with deadline scheduler

    Hi, I recently migrated from Proxmox 3 to 4. Workload: 1TB SSD with 12-hourly sequential write (direct IO) and random read (buffered IO). Wait IO increased massively. It's not about ext4 journal/barriers ;-) 1. Mark: Proxmox 4 upgrade 2. Mark: Switch from deadline to noop In a later stage I...
  19. [Q] LXC configuration wizard: what is "CPU limit" & "CPU unit"?

    @gkovacs You can assign single cores to lxc containers with "lxc.cgroup.cpuset.cpus = 2,3" for cores 3 and 4 in /etc/pve/lxc/<ID>.conf and it will correctly display only 2 cpus in /proc/cpuinfo. I recently stumbled across this issue as facter for puppet reported always all cores of the host...
