bbgeek17 replied to the thread WARNING: drivers/iommu/dma-iommu.c:1953 at dma_iova_link.That's awesome to hear! Glad we could help! @fabian pinging you here, It may be worth for PVE team to look at including this fix sooner than later! Cheers Blockbridge : Ultra low latency all-NVME shared storage for Proxmox -... -
bbgeek17 replied to the thread PBS vs Veeam B&R Proxmox Plugin - QEMU live snapshot implementation & shared LVM storage.@Johannes S: I could be mistaken, but it appears to me that you and @iceph03nix are talking about the same thing : Veeam's agents. @iceph03nix : A dedicated backup/recovery company has years of head start here. It's in Veeam's DNA. Proper...

I want to reference below info/link ... I assume that the Starwind PVE thin plugin is also affected ... at least you should be aware .... Why LVM-Thin Cannot Be Shared Storage in Proxmox... -
bbgeek17 replied to the thread Configure a Fibre Channel LUN as a directory in a cluster..Hi @jorge barriga , You should look into OCFS. There are a few 3rd party guides floating around, including on this forum. There is no official supported way to do what you want with PVE framework.

bbgeek17 replied to the thread [SOLVED] Pinning vCPU causes 100% cpu pressure stall, using isolcpus.No, just this VM. isolcpus already keeps everything else off those cores, other VMs included, so nothing to change there. I meant the affinity: line on this VM. Since you're pinning the vcpu threads by hand anyway, think of affinity: as where...

bbgeek17 replied to the thread PBS vs Veeam B&R Proxmox Plugin - QEMU live snapshot implementation & shared LVM storage.Hi @alma21 Only Veeam can give you this level of technical details. From our testing of their initial plugin release - they bypass the PVE completely and interact with QEMU directly. the filter is used with and without fleecing. Fleecing...

bbgeek17 reacted to Tmanok's post in the thread [TUTORIAL] How to install Mac OS X Snow Leopard (10.6) on PVE 8-9 with Like.
Hi Everyone, After reading through BBGeek's tutorial earlier today about LVM-Thin, I was inspired to share an educational article I recently published on my blog. The article explores Mac OS X Snow Leopard Server, a remarkable operating system...

bbgeek17 replied to the thread WARNING: drivers/iommu/dma-iommu.c:1953 at dma_iova_link.Hi @RobertKih Good news... It is not the disk. Those EIOs come from the kernel's DMA mapping code, before the write ever reaches the drive. That's why your smart-log is clean. This looks like a block layer bug in 7.0.14. Split bios lose their...

bbgeek17 replied to the thread Recent PVE Kernel 7.0.14-17-pve NVME drives is not availabe.@fabian, in case this turns out to be related to the PCIe link retraining regression from 7.0.14-7 (https://forum.proxmox.com/threads/7-0-14-7-kernel-breaks-pci-link-training.185549/), plain lspci -v won't show the link registers. lspci -vv as...

bbgeek17 replied to the thread Proxmox VE 9.2 – sporadic iSCSI NOP timeouts / DID_TRANSPORT_DISRUPTED with Dell PowerVault ME5 and Intel E810.Hi @huganega, Good news, this lines up with what we thought was going on. Let me pin one thing down, though. With net.ipv4.tcp_shrink_window=1 set, are the timeouts and transport disconnects actually gone, or just less frequent? I want to know...

bbgeek17 posted the thread [TUTORIAL] Why LVM-Thin Cannot Be Shared Storage in Proxmox in Proxmox VE: Installation and configuration.Hi Everyone, Every few months someone asks some version of "why can't I use LVM-thin on my shared SAN LUN?" Thick LVM works fine as shared storage, but has no native snapshots. LVM-thin has snapshots but is local-only... it's natural to wonder...

bbgeek17 replied to the thread Kubernetes CSI with shared FC luns (LVM storage, snapshot as a chain).The design is what worries me. Disks owned by a dummy VMID and moved between VMs by editing configs through the API. Clever, but it does not hold up when things fail. Snapshots: that endpoint is a copy, not a snapshot. It won't give you a chain...

bbgeek17 replied to the thread Proxmox in enterprice environments with shared fc storage.@rbremer, another AI-generated driver... They've been coming in droves lately. It even modifies the PVE source files! The problem with most AI-generated integrations is that they sound convincing, are thoroughly documented, and are subtly broken...

bbgeek17 replied to the thread Proxmox in enterprice environments with shared fc storage.@rbremer discussing CSI is a big conversation of its own and deserves a separate thread, but for future readers: which CSI driver is this? Separate from the driver: this type of PVE/K8s combination works, but it isn't reliable. Proxmox tracks...

bbgeek17 replied to the thread Proxmox VE 9.2 – sporadic iSCSI NOP timeouts / DID_TRANSPORT_DISRUPTED with Dell PowerVault ME5 and Intel E810.Intriguing. Nothing in your data points to a root cause, and it doesn't look like the Dell. Our best guess is a Linux issue. That said, we run a lot of iSCSI with PVE in the field and haven't seen any issues at customer sites. This suggests...

bbgeek17 replied to the thread Proxmox in enterprice environments with shared fc storage.You've got it. That's exactly why SUSE put OCFS2 on corosync, kernel DLM and Pacemaker. One membership, one fencing authority. As for doing the same on PVE... someone still has to pay to develop, debug, and support it. Not my circus not my...
