Hey there. Thanks for the reply! Agree, I'd like to bypass the PERC altogether and get a similar system to the R740XD I've got running my PBS, and connect the back plain straight up to the motherboard via PCIe risers. Issue is: I don't think this is doable on a 650XS...

Bonjour all, I'll be retiring 3 Dell 650XS from their current jobs soon™, and I would like to put them in a CEPH HA NVMe backed cluster. Currently, those servers are running a SATA/SAS backplane with a PERC H755 running the show. My plan would be to replace that with a NVMe backplane and a...

An update on this : The maximum for both values is apparently 32. I'd need more benchmarks to plot some kind of "time reduction per worker", but setting the values to 12 workers and 4 readers has brought down the verify time from around 10h to ~4h. Bringing the numbers up to the maximum value...

Hi all, Since 4.0 (I think?) you can tweak the number of readers & workers for the verify job. I've set mine to 12 workers and 4 readers, and it cut the verification times by half. Do keep in mind this is a NVMe backed ZFS system, YMMV. Are there good practices to set those values? Do you have...

Hi all, First, I wanted to thank the Proxmox Team for their work on PDM, as this tool will certainly help us to manage our multiple clusters / PBS across datacentres. Now, I'm playing with this in the lab, and was wondering what were the mandatory permissions in order for PDM to work? As I'm...

Bonjour all, I've upgraded a lab node to PVE9 today. Everything went well until it didn't. This lab setup uses a virtual router for its networking. On reboot, the VM failed to boot with this error : WARN: no physical CD-ROM available, ignoring kvm: -blockdev...

Hi all, We've (finally) decom'd an old PBS which also had an NFS share from ancient (PVE 5.X) times. To my surprise, however, my PVE backup scripts started failing (well, after I remembered those existed and switched them to the new PBS). They were stuck on the /mnt/pve/ directory. In here...

Hi all, Following https://forum.proxmox.com/threads/hard-drive-strategy.137806/, We've managed to convince the bean counters to allow us a bit of money to get backup servers. Now, the configuration I got is a bit different from the suggested configs in the previous threads. For now, we've...

Hi All, Happy new year! Best wishes to everyone. I have been trying PDM to see how it could fit our proxmox deployments. So far, I have 3 VMs, two PVE and one PDM. Everything seems to be working fine, but it appears nodes need to be able to talk to each other to migrate VMs. Is there a proxy...

Hi all, We've (finally) got a long-term storage, centralised, last resort PBS where all the other PBS go and dump their backups into. I want to add a Read-only account of which every cluster will have a token of, so that in case of a disaster recovery process, I can restore backups from this...

Hi Bbgeek17, This is planned, this forum post is mainly so that the poor soul finding themselves in the same spot has a workaround.

Hi all, A bit of a weird one here, leaving this here in case anyone finds themselves in the same boat as we did. Colleague installed a VEEAM backup on a clean installation of Windows Server 2019, wanted to add a Dell DD6400 Data domain as a repository. This was already working on another VEEAM...

Yes, that's the idea. A complete corosync should in theory never happen, but I've learned in this line of work that you don't say "If it happens" but "when it happens". So testing out in the lab is the best way to prepare for unplanned network dissasembly at 4am on a saturday :D

Well, this didn't last long, as the watchdogs did their job... The whole thing rebooted and decided it wanted to behave again. Cluster is now up and running again. Weird behaviour, though I kind of expected it before unplugging the whole thing.

Hey all, Currently testing CEPH and Proxmox HA on a multi datacenter configuration (with black fiber, so sub ms latency.) I tried to recreate the worst scenario possible : what if all nodes lose the corosync layer? This should never happen, but that's what the lab is for. I'm using Proxmox...
