bbgeek17 replied to the thread Proxmox HA rebooted all my nodes....You've already received good pointers on troubleshooting and should continue digging into the logs. That said, the above description is very worrisome... You had 10-node cluster where 8 of them were failing to start services. We don't have... -
bbgeek17 replied to the thread Weird issue in upgrading from 8.4 to the current 9.2.10.Hi @choctaw, welcome to the forum. Did you save any command-line output from the time you were attempting the upgrade? Frankly, based on the iterations of troubleshooting you described, but without the corresponding command output, it is...

bbgeek17 replied to the thread [TUTORIAL] What Replaces SRM and vSphere Replication on Proxmox?.Here's a slight refinement to my live restore description above, after more time in the source. There are three different sizes at work. I had them blurred together. The guest read is whatever size the guest asks for. The fetch from PBS is...

bbgeek17 replied to the thread LVM Snapshot-as-Volume-Chain: Newly created qcow2 image reuses old guest data after VM deletion.Hi @krisshurley , we covered behavior related to your findings in our KB article a while back: https://kb.blockbridge.com/technote/proxmox-qcow-snapshots-on-lvm/#data-consistency-and-information-leak-risks One approach would be to wipe the...

bbgeek17 replied to the thread Proxmox + Ceph across 2 datacenters.Hey @abhijithiaaxin, welcome to the forum. Whether it is a single-DC deployment or a split-DC deployment, you generally want an odd number of nodes in your cluster. But, as others have pointed out, a split-DC installation requires three...

It has been ready for years. A high-friction CLI/UX workflow is not the same thing as a system being "unusable" or "not production-grade." Thousands of enterprise nodes run multipath iSCSI in production every day—it just requires Linux systems...

bbgeek17 replied to the thread [TUTORIAL] What Replaces SRM and vSphere Replication on Proxmox?.Thanks for the tracker link @robertlukan . It also affects testing - cloning from the secondary is a common way to practice a recovery without touching replication. For the 50TB question, @alexskysilk'` math is the way to figure it. Two things...

bbgeek17 replied to the thread [TUTORIAL] What Replaces SRM and vSphere Replication on Proxmox?.Thanks, this is great detail. The command transcript especially. With krbd the snapshot mode should be fine since it doesn't need the journaling feature on the image. Journal mode is a different story though. There was a full patch series for...

Hi @bbgeek17, In our context, we are preparing configurations intended to be instantiated by non-specialist departments; we are therefore prioritizing ease of implementation. 1. At the very beginning we followed multiple docs, mainly... -

bbgeek17 replied to the thread [TUTORIAL] What Replaces SRM and vSphere Replication on Proxmox?.Thanks, @christophe! That's more configuration coverage than most reports we've found. "The multi-cluster equivalent of intra-cluster pvesr" is a good way to put it. Since you've run both modes in both directions, a few things you're in a rare...

bbgeek17 posted the thread [TUTORIAL] What Replaces SRM and vSphere Replication on Proxmox? in Proxmox VE: Installation and configuration.Hi Everyone, Disaster recovery keeps coming up with folks moving off VMware, usually as some version of "what replaces SRM?" We've answered pieces of this in threads for years, so we finally sat down and wrote the whole thing up properly...

bbgeek17 replied to the thread [TUTORIAL] Proxmox VE vs VMware ESXi performance comparison.Hi @grass127, We do have a lot of this data internally, but it isn't organized as methodically as the original tech note was, so it's hard to publish anything rigorous. What I can tell you is that the relative changes in performance are not...

bbgeek17 replied to the thread Upgrade from Proxmox VE 8.4.x to 9.1. Veeam Related.Hi @hishamrixs, welcome to the forum.

bbgeek17 replied to the thread NVMe Over TCP - Proxmox VE.A few notes based on our experience with NVMe/TCP and PVE: Your performance expectation should come from your storage stack, not your choice of protocol. The transport is usually not the bottleneck in setups like this. If you're seeing latencies...

bbgeek17 replied to the thread Intermittent I/O errors on SAN-backed VM disks (Proxmox VE 9.2).Given your report that you have not found any IO related messages in "dmesg" and "journalctl" that is a pretty strong indication that the error is coming from a higher application layer.
