    czechsys replied to the thread Outgoing mail from internal servers rejected with “Relay access denied” in PMG.
    PMG is mainly for mailserver to mailserver communication. If you are trying sending mail from non mailservers, send those mails to exchange first. Or https://www.postfix.org/SMTPD_ACCESS_README.html#relay and test.

    czechsys replied to the thread Hardware advice (or "questionable Proxmox performance on nice box").
    Disabled power saving states on the Dell? Firmware updated? SSDs are enterprise or desktop versions? I have feeling, you have disk problem, missing virtio drivers in Window VMs etc, but nothing concrete, no VM config/pve versions written. Maybe...

    czechsys replied to the thread Test migration stuck.
    MTU is 1500 for all servers, switches has 9216. Remotes the same location, the same switch and vlan. Because internal CA, fingeprints (FP): Configured for REMOTE1:8006: from pveproxy-ssl.pem FP - BUT - it automatically detects intermediate...

    czechsys replied to the thread Test migration stuck.
    Nothing spotted yet, because remotes are in production and there is nothing non-standard even on netdata (i can miss something of course). Today 4x test moving real vm 10+200 GB, migration fails for 2nd disk around 17-19/16-17 GB position...

    The same test as with Alpha version. The same remotes, upgraded to PVE 9. Migration of the 2nd disk stucked, manually stopped. Remotes: pve-manager/9.0.6/49c767b70aeb6648 (running kernel: 6.14.11-1-pve) 2025-09-19 11:28:53 remote: started...

    czechsys replied to the thread Mark found message as spam via webGUI?.
    That's not possible, because message doesn't exists on PMG after delivering to mailserver. So nothing to scan/learn again.
  • C
    czechsys replied to the thread Is clustering production-ready on Proxmox VE 8.2.2?.
    Don't use 8.2.2. You will have problem install another host with this version. Use last PVE version, now 8.4, or go directly to 9.
  • C
    czechsys replied to the thread A few questions about Backup.
    Filebackup of the host. Especially /etc/pve for pve specific configuration, large part of it is handled by cluster, but something is node dependent (example: certificates). Search forum at least.

    czechsys replied to the thread New to ProxMox and stabillity.
    Running PVE 9 on DL360/380 Gen 8-10 without problem. You can install rsyslog, attach monitor for kernel dump, maybe there will be something not in journal. It's standard debian anyway. Other thing - firmware, power, etc etc etc.

    czechsys replied to the thread Best logs to collect on Proxmox when LVM volumes disappear due to SAN/FC issues.
    Without upgrading the 2nd SAN node: What will happen, when you shutdown the 2nd SAN node? What will happen, when you shutdown the 1st SAN node? I think, it's SAN support thing mainly, because with 2nd SAN node upgrading it blocks something...

    czechsys replied to the thread Proxmov PVE9 Upgrade AppArmor Error.
    That's docker problem versus apparmor, not PVE related. Debian 12 didn't have active apparmor, but debian 13 has it by default. I encountered the same problem with giltab-runner + docker. Profile docker-default is created by docker service on the...

    czechsys replied to the thread NFS server install.
    It's better to have container/vm for any service and leave proxmox doing only proxmox things.

    czechsys replied to the thread Spam Mails into Zimbra Spam Folder.
    Configure zimbra to move mails to spam folder. PMG is only gateway, not mailserver with mailboxes.

    czechsys replied to the thread Migration from ESXI to proxmox: Shared LVM issues.
    I have SAN with 3 luns connected with multiple destination's paths by multipath without problem. But i used mainly cli for configuration at the end, not gui. Looking on your debug, i think problem is somewhere 1] acl on SAN 2] iscsi/multipath...
