After battling to understand these settings myself, and then carefully reading the Postfix documentation over and over again, I conclude these are both very good settings to enable by default. 1. The first setting, "Reject Unknown Clients", does a more intense PTR check and if there are...

This is how I find it in the log: More specific, you can do this: Then I get this: In the UI I one can see this: The only anomaly I found on a new installation was that `clamav-freshclam` wasn't started: But of course that was quickly sorted out with:

I can't vouch for Hostbill because I've never used it, but I'm an avid user of WHMCS. From the client side, the Modules Gardens WHMCS Proxmox VE module is really great. It's easy to understand, intuitive, and it's high quality software. Also they really keep things up to date - as of today...

Ah man I would love a HOWTO for Virtualmin!? We have many Virtualmin clients who are complaining about spam, especially phishing. Virtualmin has SpamAssassin by default but ClamAV is a challenge with at least 2GB RAM just for that. Example phishing problem: SpamAssassin score = 2.7, need 5.0...

Is there perhaps a step by step guide how to move backup from one PBS server to another? We have a lot of space on one server, and less space on another server. We want to try and load balance across the two by manually moving some VM backups from the one to the other. So far it seems...

I might have a somewhat similar setup to yours. Components used: PVE 7.4 TrueNAS core. My NAS is a VM. I connect to TrueNAS core using iSCSI and https://github.com/TheGrandWazoo/freenas-proxmox My drives are passthrough (see bottom links) TrueNAS is set up all defaults ZFS, RAID5. I have two...

Thanks @Moayad Unfortunately I didn't see your reply and below is how I think I fixed the problem. Your technique is "change quorum to have one expected vote". It seems what I found what "make file system not read-only to affect changes". With regards to pvecm expected 1, is there something...

I dont' know how you all got this right because on my 7.4 system files /etc/pve are read-only. Any advice?

I had to migrate one of the nodes of my four node cluster to another data centre. The IP address had to change. Now I've googled how to change the IP address of the node that is currently down but I'm struggling to find a HOWTO or concrete information that doesn't overlap or contradict. Are...

> run PBS bare metal with local SSD storage on dedicated hardware and not virtualized on top of PVE Maybe you won't approve of my setup: - Virtualized NAS running TrueNAS - The NAS VM has directly connected drives via Proxmox and ZFS 3 drives - PBS VM connected to virtualized NAS Why? I...

Thanks so much @ggoller ! Naively I thought that since I'm replicating VMs across to another host, I could use this method to restore the backup. I'm actually trying trying to solve this problem and will conduct more research and try more things: Geography A: PBS Server Geography B: PBS Server...

> but not the recommended scenario Why is it not recommended to install qemu-guest-agent on PBS?

My backup sync jobs are working 100% between two servers. However, when I browse the remote datastore linked PBS server in the cluster servers tree, I don't see the VM backups. Here is the tree view of my environment: I have a ton of backups on backup05, where I have a Sync Job from...

> Is there anything else running over the same network as corosync? Hi @mira , I see there was no reply to this question, so I have a related one: Can Promox VE Cluster work over a WAN, over the internet? We have a 1 gbit/s DC and a 200 mbit/s DC and I'm trying to get it working but I'm...

Hi @Chris, I made some progress due to your on-point questions: Which leaves me with the question, is your VM actually running? The VM wasn't running. I've now instead chosen a running VM and backups are working! It took around 3 minutes to backup the 20 GB VM from the one data centre to the...

Hi there, I have a newbie question. We have two data centres, with four VM hosts, Data Center A and Data Center B. I have an installation Proxmox Backup Server in Data Centre B. I tried to backup a VM in Data Centre A to the PBS server in Data Centre B but it fails with an obvious error...

ZFS host block size configuration for disk I'm moving: zfs get volblocksize pool/vm-102-disk-0 NAME PROPERTY VALUE SOURCE pool/vm-102-disk-0 volblocksize 4K - PVE Storage configuration: cat /etc/pve/storage.cfg dir: local path /var/lib/vz content...

Hi! When I move a VM's storage from `local-lvm` to a TrueNAS Core based ZFS volume over iSCSI, I get the following warning: Task viewer: VM 102 - Move disk create full clone of drive scsi0 (local-lvm:vm-102-disk-0) Warning: volblocksize (4096) is less than the default minimum block size...

Sorry to reply to an old post, but I am so curious to hear what happened? I just upgraded two Proxmox servers from 7.1 to 7.4 and I also got these messages: File descriptor 3 (pipe:[837801799]) leaked on vgs invocation. Parent PID 1101896: grub-install.real File descriptor 3 (pipe:[837801799])...

It took me a year to isolate this problem but finally by logging a ticket and double checking everything I finally notice this rookie mistake. The default for Hard Drive was set wrong! It's working now.
