Aalexskysilk replied to the thread proxmox (VSphere VMWare to Proxmox migration).This is not a PVE, or even Linux/SLES problem. This is linux troubleshooting 101. You have a hanging task on the 2nd partition (presumably root) which gives you two vectors of troubleshooting- 1. host bus- change the host bus for your root...

Aalexskysilk replied to the thread Feedback: lack of host backup has me reconsidering use of Proxmox.I think you have a misconception of what an appliance is (or rather, what seperates an appliance from a managed software stack.) an appliance doesnt NEED backing up. its an appliance. restoration of a failed appliance is just redeploying it. In...

Aalexskysilk reacted to portedaix's post in the thread [SOLVED] Backup speed regression: 2h20m → 8h39m after PVE 8→9 / QEMU 9.2→10.1 / Ceph 18→19 upgrade with
Like.
Hi, That was a beginner mistake. Real root cause (found 2026-05-06): discard=on was missing from scsi1 in the QEMU config. For over a year, every ext4 TRIM was silently dropped by QEMU and never propagated down to Ceph → 2.7 TiB of orphaned RBD... -
Aalexskysilk replied to the thread iscsi direct luns with multipath.fiber channel multipathing works effectively identically to iscsi; once the devices are captured by multipathd they'll just show up in /dev/mapper and you can use them as any other mapper device- so you can put a vg on it or map is as a drive...
-
Aalexskysilk replied to the thread Is there a way (or a guide) to build Proxmox without just installing Proxmox?.Linux admins have built a "Proxmox" for years before PVE became a thing. the reason we use PVE and not our homegrown solutions is because they put everything you need together for you. Its not that you COULDNT do it yourself- it would just take...
-
Aalexskysilk replied to the thread Use Disk PassThrough or Raid-0 for PVE with Ceph (Testsystem).This is a major point. using ceph on this sort of POC will not teach you how to actually use ceph in production since you wont be able to actually put the type of load on it that would be meaningful. Is your intention to use this knowledge to put...

Aalexskysilk replied to the thread cross-cluster migrate with ISO on cephfs.short answer: just create a script to detach iso-migrate-attach iso. longer answer- dont keep iso's mapped without purpose.

Aalexskysilk replied to the thread VMware Migration - Scenario & Seeking Advice.its iscsi, sas, or fc. doesnt change the process meaningfully.
-
Aalexskysilk replied to the thread VMware Migration - Scenario & Seeking Advice.To summarize- you want to replace a single host vsphere with a single host pve. Easy peasy, but you need to understand that you will need sufficient staging space. another aspect is the backup. reading between the lines, veeam is deployed as a...
-
Aalexskysilk replied to the thread Yet another "ZFS on HW-RAID" Thread (with benchmarks).Everything is predicated on your risk tolerance. in a homelab, I have no real qualms about running a simple ext4 filesystem on a single HDD. like you, I dont remember ever losing a single bit (at least not being aware or impacted by it)- but...
-
Aalexskysilk replied to the thread Proxmox 8.4 soon EOL, Do i NEED Px Backup Server?.Its entirely up to you. it is POSSIBLE to set up a hypervisor, a pbs vm, import the data, and restore- but by that logic you could just rebuild all your vms from scratch too. your RTO/RPO policies are your own.
-
Aalexskysilk replied to the thread Proper way to set up a Proxmox cluster on a dedicated VLAN (separate from Management).different ports = different interfaces. discussion about proper nic redundancy notwithstanding. for the context of conversation, interfaces are logical. While for corosync you want link seperation as well as logical, you might also want to...
-
Aalexskysilk replied to the thread Proxmox 8.4 soon EOL, Do i NEED Px Backup Server?.PBS hosted on the same pve instance that its serving to back up becomes effectively useless should you brick the host- which I presume is the primary concern this thread is meant to address. The approach I would suggest in such a case would be...
-
Aalexskysilk replied to the thread Curious about kernel updates."kernel" being "out" doesnt mean anything directly to a distribution with a support policy. Instead, the maintainers of your linux distribution (in this case, ubuntu) will backport important changes that are deployed to downstream kernels...
-
Aalexskysilk replied to the thread Shared Remote ZFS Storage.I would retort with calling a solution shady because its imperfect to be an irrelevant argument to begin with. The difference between "first tier" and not ISNT that they are (perfect), its that they have the engineering capacity and support staff...
-
Aalexskysilk replied to the thread Shared Remote ZFS Storage.There are vendors, and there are vendors. NetAPP is first tier. the fact that my wife's nephew put together a NAS using gum and bailing wire doesnt make him of the same caliber. As for trusing your data... on prem storage exists precisely so you...

A> Battery backup of a single cache still makes it a SPOF No, it doesn't. In your scenario, another, prior and unaddressed, failure is required to make NVRAM (and/or other component(s)) a potential single point of failure. It doesn't make it a...

Aalexskysilk replied to the thread Proxmox roadmap - future direction of snapshot‑as‑volume‑chain.Not an endorsement since I have not used myself, but Starwind StarLVM (the substrate of Starwind VSAN) looks like it would do what you ask. https://www.starwindsoftware.com/starwind-virtual-san

Aalexskysilk replied to the thread confused...CEPH delivering same performance on 100G as it did on 1G test.that explains your observed performance. LACP is your first choice. if thats not possible, use active-backup and MAKE SURE the switches have plenty of bandwidth interconnecting them. balance-xor sounds good on paper but not in practice. set...
