    Proxmox VE Wikipedia Article - Please Review

    Hi Everyone, As Proxmox VE has grown quite substantially since I began using it, I thought I'd blend together my Wikipedia editing with my in-depth knowledge of the software and my general awareness of the company behind it. Having received the Proxmox VE Advanced Certification in the 7.2 era...

    Proxmox VE 9.2 – sporadic iSCSI NOP timeouts / DID_TRANSPORT_DISRUPTED with Dell PowerVault ME5 and Intel E810

    Hi Huganega, Ok, that 128/128 result is probably the most interesting thing you've found yet. The fact that the active SCSI path reaches exactly 128 outstanding requests, stops completing them for 12-14 seconds, and then sdk_ioerr_cnt increases by exactly 128 when iSCSI recovery occurs is...

    Laboratory Cluster

    Hey Frankz, Realtek cards "work" on most Linux hosts, but server admins don't trust them due to well-earned stigma. NICs are very affordable, I have a pile of them. But an I340-T4 for under $40 CAD or PRO/1000 4 Port for the same price will be more reliable. I don't always recommend server...

    Proxmox GUI question marks when adjusting/resizing storage with enterprise SANs

    Hey NoriCopperBrand, Good news, nothing wrong with your equipment! In other news, you are in for some pleasant learning. First major thing: Do not run these commands on every PVE node: rescan-scsi-bus.sh multipathd resize map mpathX pvresize /dev/mapper/mpathX Also, after you run the resize...

    Laboratory Cluster

    Hi Frankz, Ok, now I understand, thank you. Yes, in studying those CPUs, I can see clearly that three of them would offer you a substantial upgrade: Host CPUCores / threadsTurboTDPPassMark CPU MarkSingle-thread bench i7-97008 /84.7 GHz65 W13,1752,744 E-2224G4 / 44.7 GHz71 W7,5262,688...

    Laboratory Cluster

    Hi Frankz, Wow what a mishmash of random computers you have. I don't quite understand your problem, however. What is it you're looking for someone to advise you on? The storage, the CPU specs? If it's a laboratory, the best thing is to experiment and learn along the way. Thanks, Tmanok

    Proxmox GUI question marks when adjusting/resizing storage with enterprise SANs

    Hey NoriCopperBrand, Sounds like a storage slow down to me. Something is unhappy about the rescan as you point out. When PVE shows a question mark on a storage device it means it has lost contact with it- or more specifically pvestatd is unable to collect statistics and therefore can't display...

    High Availability Functionality

    Most likely something network related or storage related. If it's shared storage, then you're just migrating RAM while a VM is running. If it's an LXC or the VM is off, hardly anything is actually moved so something to do with the locking on the storage device may be causing an issue. If you...

    Horrifically slow download speeds for download.proxmox.com?

    Hey H@rald, Community members have shared scripts in the past, so unless a policy change has occurred, I'm sure you'd be welcome to link to a GitHub repository or something similar. I suspect that as China is moving away from the likes of Microsoft, Github may no longer be the safe harbour it...

    MTU Not being correctly set between host and LXC

    Hi Everyone, I think I may have come across a bug? When configuring MTU on PVE, whether the GUI or CLI is synonymous, I checked both and MTU was setup to 1450, it doesn't actually apply to an LXC in the latest PVE- actually I am moments from rebooting this host to determine whether 7.0.14-14 &...

    Horrifically slow download speeds for download.proxmox.com?

    Thanks, H@rald, that's good advice. And thanks, Thomas, I haven't been back on that site to check but I will shortly.

    Proxmox VE 9.2 – sporadic iSCSI NOP timeouts / DID_TRANSPORT_DISRUPTED with Dell PowerVault ME5 and Intel E810

    Hmm well there goes my PAUSE frames storm hypothesis. There was no corresponding jump in link_xoff_rx.nic, no CRC errors, no drops, no E810 reset and no physical link loss. So I was wrong... But that narrowing TCP window is TCP-layer backpressure, which is rather similar to Ethernet flow-control...

    Horrifically slow download speeds for download.proxmox.com?

    Hi Everyone, Hey PVE Staff, Is it just me, or are the web servers for download.proxmox.com unbelievably slow? I'm updating a PBS instance after several months and realizing it will take hours.... This is naturally, inconveniently interfering with a maintenance window. Shame on me for not...

    Proxmox VE 9.2 – sporadic iSCSI NOP timeouts / DID_TRANSPORT_DISRUPTED with Dell PowerVault ME5 and Intel E810

    Hi Huganega, Ok, a few things from your output might be worth examining, but I have to ask a question I normally ignore because I'm vendor agnostic 99% of the time. Are you using a Dell recommended DAC? 25GbE has caused me trouble in the past with some products because it has additional...

    Proxmox VE 9.2 – sporadic iSCSI NOP timeouts / DID_TRANSPORT_DISRUPTED with Dell PowerVault ME5 and Intel E810

    Hey Everyone, I think there's something pretty overlooked here: Dell's ME5 documentation explicitly says that for iSCSI usage you must have symmetric flow control enabled on the interfaces. If the E810 and ME5 aren't agreeing properly on pause behavior, bursts can overrun buffers on the active...
