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...

All nodes in cluster share the same LDAP configuration - effectively they use the same ldap server(s). I have 3 ldap servers, they are synchronized, so it does not matter which one is used by which pmg node, but... of course I would like every node use the "closest" ldap server. Is it possible...

My PVE node is inside LAN. I want to use ACME: 1. If I redirect port 80 on firewall - it works! 2. How to configure apache on dedicated host to proxy acme requests to PVE inside LAN?

How actually works retention/pruning when datastores are synchronized via the remote feature? Must retention config be the same on both source and destination? What happen when a backup is deleted on source? Will it be automatically deleted at destination? And what if backup is deleted at...

I want different vm's to be backed up to different namespaces in the same datastore (for example separate ns for each pve pool). Mostly because they are going to have different retention setup. Do I have to add the same pbs storage multiple times to the pve? Or do I miss something...?

Configuration -> Backup/Restore -> Proxmox Backup Server Why backup stored in PBS is not ecrypted at all? Configuration dialog does not have "Encryption" tab: Equivalent dialog in PVE allows for encryprion:

I want to use proxmox-backup-client to backup 500k small files (+-100GB total), which usually stay not changed between backups. 1. Is this good idea? 2. Will the client automatically upload only new/changed files? (good) Or will it every time upload all the files and it's server's job to...

As far as I understand - one server may "pull" datastore from another one. ("Sync jobs" in configuration.) Is it possible/planned the other way? I want a local server (hidden behind firewall) to push its datastore to a remote one (publicly accessible).
