Hi. So we are testing a couple of Synology Rackstation NAS in HA mode. Repeatedly crashed one of them for testing, now one of the VMs are stuck in "automatic repair boot" loop. Proxmox is too quick to let me press any F5 or F8 combo between Proxmox bios and windows loading. I have tried all...

Hi. For info we have 2x synology rackstation rs2421rp+, both with 8x 8TB Ironwolf disks. The NAS are connected via 10gbit to the proxmox servers. These are gonna be put in Synology HA mode. But before that we are testing each of them in different RAID setup to check performance. The share is...

Ceph went haywire after a switch hiccup, and i am trying to figure out what went wrong. So we have 6 Proxmox servers. All with double 10Gbit network cards for Ceph. All servers are connected to two 10Gbit Switches in Active-Backup mode. Each of have 4 SSDs running as Ceph OSDs The servers...

Hi. So i have now tried with 3 different sets of network cards, same result. The proxmox hypervisor works just fine. The VM wont get an IP unless I disconnect one of the network cables. And when i reconnect it, the VM looses connectivity. I have seen alot of posts on this forum with people...

Hello. We are a little late with this upgrade, and still running Proxmox 6.4-9 I have seen the guide here: https://pve.proxmox.com/wiki/Upgrade_from_6.x_to_7.0#Known_upgrade_issues Is it still safe to upgrade from this version? Would that be from 6.4-9 to 7.2? or 7.0? If this fails and we...

Hello. So i just updated one of our servers with zfs in raid 1. One of the disks where REALLY slow, update was stuck for over an hour, the disk had 3 checksum fails in zfs. Using smartctl took over 10 seconds to post, compaired to the other disk. Once i took the disk offline in zfs, the...

Hello. We currently a NFS share that hosts backup and 2 VM disks. Is it possible to change this live? From /mnt/arrayb to /mnt/arrayb/proxmox Alternatively i could transfer the 2 vm disks to CEPH-SSD storage, remove the NFS, and then add it again. Thanks.

Hello. This is the second time this has happened. I don't remember if the last time was when upgrading from Proxmox 5to6. We got 6 proxmox servers in a cluster, using each of them for ceph storage as well. Both times we have, migrated all VMs off the proxmox node, updated it, rebooted...

Hello. We recently installed 3 new Proxmox servers, now running 6x Proxmox servers. 2 of the new servers were identical (HP DL360p G8). The only difference between these two new servers are that the one with problems are running Seagate 1TB Firecuda SSHD boot disks in RAIDZ1. All of these...

Hello. We have a psyhical machine running windows server 2012. This server runs Shadowcopy backup. Is it possible to migrate/import a full image shadow copy image, directly into Proxmox? Thanks.

As title says, does this do anything? any good? or any bad? My guess is that Ceph handles this by it self. Thanks :)

Hello. We have one server using more memory than it's suppose to do. I have configured zfs to only use 512MB ram max. And i have configured the Ceph OSDs to use 1GB each. But still i am missing root@proxmox1:~# arcstat time read miss miss% dmis dm% pmis pm% mmis mm% arcsz...

Hi. my /etc/modprobe.d/zfs.conf on all servers look like: options zfs zfs_arc_max=573741824 I have tried running: update-initramfs -u on all servers. and the result currently is: root@proxmox1:~# cat /proc/spl/kstat/zfs/arcstats | grep c_max c_max 4 67530100736...
