best advice I can give anyone troubleshooting is learn to search the forum. https://forum.proxmox.com/threads/cannot-access-web-gui.107376/

post the output of systemctl -l --no-pager status pveproxy

post the output of zfs list -t all all your questions would be answered there.

any time you build an environment with such nested dependencies you're making a unsupportable/difficult to support solution. As a matter of design, your storage layer and your compute layer should not be interdependent. Since you've decided that your storage layer is to be governed by truenas-...

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 drive to SATA. does it boot now? 2. partition...

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 context of PVE, its a lot less of an appliance...

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 redirect to a vm. That isnt a function of PVE. Ask...

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 you the relative man years that it took to pve team...

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 together a production cluster, or just for funsies?

short answer: just create a script to detach iso-migrate-attach iso. longer answer- dont keep iso's mapped without purpose.

its iscsi, sas, or fc. doesnt change the process meaningfully.

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 virtual machine with storage provided as a vmdk by...

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 similarly I spent the entirety of my youth driving...

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.

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 consider link fault tolerance for your guest bridges...

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 use an external drive and use vzdump directly to it...

"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. Translation- dont worry about the new kernels. Unless...

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 to identify, document, and resolve in a timely...

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 dont have to. if you meant trust in their...

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
