When I reboot node, all bitmap status will be cleared and next backup will be full right? What if I take snapshot of kvm with memory status and reboot node and restore zfs snapshot? Will bitmap status ok this time?

I am planing to collect stats for many pve server - around 20. Some grafana graphs wil have common datas for all servers AND some graphs will have costom data for one pve server only. So I am planing to create two buckets for each servers. One one common bucket, one for pve's own data's...

Some vms have: args: -vnc 0.0.0.0:01 for vnc connection as stated https://pve.proxmox.com/wiki/VNC_Client_Access But when backing up these vms by pbs, I got: INFO: creating Proxmox Backup Server archive 'vm/3230/2025-04-11T00:50:21Z' INFO: starting kvm to execute backup task kvm: -vnc...

We recently got JungleSec Ransomware on some of our pve servers. Elhamdülillah no damage. But there was no actual damage but only some linux kvms' boot record were broken. So we quickly restored zfs backup and all fine. But what saved us is I think zfs file system. I read some articles that...

This is probably simple question. I am installing proxmox on first nvme disk which I guess should be nvme0n1 but after install I see OS disk is nvme1n1 I even tried installing pve to second this but after install I still see /dev/nvme1n1 in gui. So how can I install PVE to nvme0n1 ? AFAIK 0n1...

I have a domain with .it extension. And it seems PMG does not block any email for that domain. More interesting thing is, email account is getting nearly 30 spam mails in just one minute. How is this possible to get such much spam mail ? One sample log: 2024-08-07T17:11:55.663981+03:00...

Is it somehow possible to allow proxmox gui/ssh access to a mac address instead ip address. ?

Sometimes, some kvms are having very very high IO like 1-2 G Disk IO: And that makes vm unresponsive. So is this related to Proxmox / VM itself or Zfs file system? Thats seems to be impossible inside vm but these vms have sql server installed. So where should go first you think?

I am running influxdb in a nat of pve kvm environment. I see randomly: metrics send error 'Monitor': 500 Can't connect to 8.8.8.8:8086 (Connection timed out) but metrics are being collected. I have forwarded 8086 to influxdb internal nat ip (in pve). What could be issue?

Today, there was an issue on nas, pbs and metric servers and unreachable for a while (all are on same hardware) then all proxmox servers had issues those were trying to connect to it. Like disks status are unavaliable. Gui is not running correctly. Vm names were missing etc. We tried all...

I have several nat moded vms in pve. I also installed pbs like this. So fas so good. But I noted today, it can not reach internet. Is there anything I need to allow? On same Pve, other vms are fine with internet, but pbs can not reach internet with internal ip (192.168.1.10). It can reach...

Do I need to create full backup regularly? I do not see such option. But AFAIK, when using incremental backups, time to time full backups should be taken. Is this same with pbs? Or I can just leave it one full backup and let rests for incrementals?

I think it is not possible to mount pbs as iso or directory storage (yet). It only store backups for now.?

How can I keep second copy of backups to an other disk. Sync job ask for pbs. I install pbs in a pve vm. And attached disk to it. I have some more disk free. So I think of keeping copy of disk in use with pbs. Or any better advise? Or should I install an other pbs on same pve not and use it...

Our Pve servers has ssd sata for only pve os. But we think of using normal sata disk (7200rpm) . Do you think if would impact on overall pve performance? Vms are running on nvme disks. We think Sata disks will last longer because ssds may be failing in any time.

AFIK, metric does not provide cpu temps. After some search, I read k10temp module is a workaround. https://github.com/groeck/k10temp So is it possible to install that module ? Or anyway to get cpu temp with "sensors -j" ?

When externalsender.com sends an email to a user behind PMG, he gets following spf error. And of course he is not allowed to send mail from PMG's ip. Why is this happening? <user@domain-behind-pmg.com>: host domain-behind-pmg.com[1.2.3.4 > (User's server ip)] said: 550-SPF: 2.3.4.5> (PMG's...

When I check memory usage in windows, total memory in use does not sound correct. Please see screen shot, that vm has total 20 GB Ram but windows show %85 in use which means 17 GB but if you look at processes it is not in total 17 GB. Maybe around 8-9 GB. Using zfs..

What is the difference of using builtin rulesets from gui or spamassian rules custom /etc/mail/spamassassin/custom.cf ? Performance / usage / easy to manage?
