I want to run two PMG nodes (in a cluster) physically placed in two separate locations, both behind NATs. Is it enough to open and redirect ports: 465 (smtps) and 22 (ssh) on both firewalls for the cluster to flawless communicate/synchronize? Of course I can set up VPN and use private IP range...

Has anyone succeed with installation of ChromeOS Flex (or FydeOS) in VM? I downloaded installation images from Google/Fyde, but I am not able to boot them up in VM. Both bios/efi boot method do not work. Efi is able to find efi partition and some files on it, but still does not boot. Fyde goes...

What is the "correct" way to automatically trim filesystems residing in lvm-thin pool? I can see there is "pct fstrim" command and I can run it manually (and it works!), but... it seems strange that such important functionality have to be done manually. Is there any "standard way" of doing it...

I have a container with a couple of ZFS mount points. One of them contains plenty of fast changing temporary data and I generally do not want to keep them in snapshots. (The problem: the dataset has <100GB, but a month of daily snapshots effectively uses 1TB of disk. because the temporary data...

I just had to restore large container and it took a lot of time. Have you thought about live restore feature? It works great with VMs. In theory it shoud be possible. My thoughts: - pbs client have "mount" feature, so it is possible to mount the backup and have all data available immediately -...

Hi, I need your thoughts... I have small local server that receives 20 or maybe 50 legitimate mails a day. I has been so for years and worked perfect. And it still works perfect, but my tracking center looks so: PMG does its job excellent - all these mails are spam and indeed should be...

In order to have replication and immediate migration - zfs storage is a must. In order to have "real" unrestricted snapshots and vm cloning feature - qcow2 storage is necessary. Did I miss something? Are there any plans to combine these features?

I have problem with borg backup while trying to back up ~550.000 of small files: [1576137.653081] oom-kill:constraint=CONSTRAINT_MEMCG,nodemask=(null),cpuset=ns,mems_allowed=0,oom_memcg=/lxc/5011,task_memcg=/lxc/5011/ns/system.slice/cron.service,task=borg,pid=2284332,uid=0 [1576137.653138]...

I have root filesystem in lvm: /dev/mapper/pve-root on / type ext4 (rw,relatime,errors=remount-ro) From time to time I get this in dmesg: [27141.449117] EXT4-fs (dm-4): orphan cleanup on readonly fs [27141.454531] EXT4-fs (dm-4): 1 orphan inode deleted [27141.454539] EXT4-fs (dm-4): recovery...

Is it possible to encrypt content of a container filesystem? For example I want to use remote storage like cifs/nfs. If the remote system gets compromised (or if I don't trust admin...) - all container data might be read, copied and taken over by "bad people". On the other hand - if the data...

Has anyone tried to set up datastore located somewhere at online storage provider? Like this or this or this. Will it work? What protocol would work best - smb, sftp? (And what about s3fs or s3ql?) I suppose it should work, but I am afraid datastore verification would need to read the whole...

Sometimes (for example after hardware update) I want to boot up PVE node without actually starting all containers/vm's. (Then I'd do some tests, necessary config updates etc., and finally reboot.) What is the "correct way" to do it? Usually I manually add "init=/bin/bash" in grub boot menu, but...

I want to designate one node to take care of sending mails in case of temporary problems. So I added this to main.cf template: [% IF dns.fqdn == 'my.other.node.com' -%] smtp_fallback_relay = [node.responsible.for.sending.of.deferred.mails.com]:26 [%- END %] The goal is: The 1st node tries to...

I have just wrote a script that helps with backups of LVM volumes - automatically creates snapshot, uploads to PBS and removes snapshot: https://github.com/michabbs/lvm2pbs Have fun! :)

How can I set up such mail filter rule? Action: BCC To: NOT one of a given list

I have 2 stand-alone pve nodes. On each of them I created Ubuntu 22.04 container from tremplate. One shows this: # ulimit -a real-time non-blocking time (microseconds, -R) unlimited core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling...

My PMG delivers mails to my another host via smtp, where Postfix forwards them to Dovecot via LMTP. Actually that Postfix seems to be not necessary - PMG should be able to transport directly to Dovecot via LMTP. (Right?) But - as far as I understand - mails will be transported in cleartext. Is...

I am trying to convert from traditional vlan config to the new "vlan aware" one. What is wrong here? iface enp5s0 inet manual auto vmbr1 iface vmbr1 inet static address 10.13.145.13/24 gateway 10.13.145.1 bridge-ports enp5s0 bridge-stp off bridge-fd 0 bridge-vlan-aware...

In order to have self-consistent backups I always use snapshots feature of zfs/lvm. I made a backup of the whole rootfs of pve node this way: - created snapshot of / (which in my case is on lvm, but could as well be on zfs) - archived the whole filesystem from snapshot - removed the snapshot I...
