But vmgenid will change... In very rare scenarios, for Windows OS (SQL Server cluster, AD PDC eg.) which are aware of vmgenid, restart after such restoration may have some unforeseen consequences. So, restoring the old vmgenid before booting the vm again OR using that kind of script/change...

Windows server 2022. I noticed lots of errors related to VSS when I tried to backup in snapshot mode, eg : Volume Shadow Copy Service error: Unexpected error querying for the IVssWriterCallback interface. hr = 0x80070005, Access is denied. . This is often caused by incorrect security settings...

Hi, I run a Win2k22 VM which is an Active Directory PDC. Qemu-guest-agent installed. In order to avoid USN rollback or Event 2089, I backup my VM in 'stop' mode. Is it safe to backup kind of VM in snapshot mode ? If yes, how to do that ? Thanks !

Hi, In the meantime, is there a way to release the ram without rebooting the node ?

That did the trick ! Thanks a lot

waow thanks it is worth a try

BCM57502

>= 15 Gbps in both directions

I'm suspecting a host issue... Using nftables instead of iptables could impact performance ?

Hi, Weird behavior for a Ubuntu Server 24.04 VM. Download speed ~500 kbps While a debian 12 VM is able to download at full speed 1000 Mbps. On PVE host no bandwidth issue, firewall on (nftables), masquarade, ipv4 forwarding activated. VMs use CPU type = host with numa activated as well...

Thanks! I don't think that network downtime is > 1 or 2sec with default parameters. The main question is how ceph handles such network outages. I guess it is OK for corosync and VMs as well. But when this happens, the entire Ceph cluster is down twice for 2 seconds. Moreover, mikrotik stable...

Thanks I also worked with FS, Dell OS10 S5248F-ON which seems to be similar to SN2410 you 're using ... Don't recall a preemption behavior on each reboot with them...

Hi, I plan to build a new proxmox ceph cluster (3 nodes). LACP 2x25 Gbps for ceph LACP 2x10 Gbps for VMs My question is related to the switches, I want mlag switches indeed. Mikrotik was my first choice due to functionalities and low budget as well. I have 2 CRS310 and have settled a very...

Hi, Can confirm the issue for 50% of my PBSs

Thanks, I'd prefer new devices :) my servers have mostly 2+ SFP28 ports so I assume I will go for a device that have at least sfp28 or 100 Gb with breakout cables
