      Anyone run into this issue on enterprise hardware?

      There is no "issue". Even those that claim that they are running into it, it's consumer drives with HA logging going to those drives. Its' nothing to do with ProxMox, it's just standard, everyday CoroSync logging. The people saying "this is system administration basics" are correct.

      Or just understanding what hardware you need for the job.

      All VM guest OS will write to the same drive as well. So 10 guests will generate 10 times as many writes + whatever the hypervisor itself is generating.

      I just checked and Crucial MX500 have 0.2 DWPD, which is not bad for a consumer drive.
      But compare that to enterprise drives that usually start at:

      1 DWPD (read-intensive) 3 DWPD (mixed use) 10 to 100 DWPD (write intensive)

      I would move PBS to the PVE environment since your just dumping data on the NAS anyways. At least then it’s replicated. Don’t forget to backup your encryption key.

      I am using a promox server with the following raid-RAIDZ-3. A variation on RAID-5, triple parity. Requires at least 5 disks. It works awesome for my VMs. It protects me fully if one disk goes down.

      Raid 5 does this natively, how is this some amazing feature?

      RAID 5 is single parity.
      RAID 6 is double parity.
      RAID 7 is triple parity.

      This is RAID 7.

      Sorry, I could've swore this said protects from 1 drive failure....

      @rjt said in Adding remote storage to Proxmox:

      @jaredbusch nfs on top of ZFS.
      ZFS should be the underlying block/fs for everything whether a single hard drive, block storage like iSCSi, file storage such as NFS or CIFS. I like TrueNAS for this purpose. As you can see, I love ZFS. My problem is I also love CentOS. Need to figure out easy ways to get ZFS on CentOS. We should all write a letter to Larry asking him to open up the license.

      Most of us here do not subscribe to The Cult of ZFS. Yes, it has a place, but not nearly like it's made out to be.

      I'll try and make a cleaner guide later..

      First, spin up your ProxmoxVE system. During the install wizard, I left the boot drive as LVM but did change it to XFS instead of ext4. You do not setup secondary drives during the install wizard. Once up, you need to create the ZFS store on each system, named the same, prior to joining the cluster. The replication process wants the ZFS pool to be named the same on both systems and you cannot name it the same (at least in the GUI) if it already exists anywhere in the cluster.
      3c9d3871-d8f6-4da0-93fd-22bf8526ef6b-image.png Then from the GUI, go to the disks of system 1.
      67ae2a41-d84b-4fbc-9cd0-4dea04cb5465-image.png then click on ZFS and create the storage pool name it, single disk, compression off.
      4379c8d3-edf1-4733-95ce-d3bc5f2400e9-image.png wait for it to show normal.
      145f1381-2d1e-4215-b29c-30e2227c00d2-image.png then repeat the process on the second system. make sure to use the same name. Now create the cluster and join the second system to the cluster.
      e9401472-ad68-433a-b569-5cc14f21552d-image.png You will not see the storage on ZFS storage on system 2 when it first loads up.
      0e6e610a-21fd-4317-9f15-336eec787af3-image.png But it does exist if you look.
      d5efc711-8126-4e30-955a-9d0deba7db10-image.png To make it available, go to storage under datacenter.
      545a0b08-72e0-4912-bf3c-f10ce2527d73-image.png edit the existing "data" and add pve2
      d8022847-45ea-46ce-be11-807f01e51449-image.png now it will show up and be available for use.
      a68a5b5c-3024-4650-869b-c36065713c87-image.png

      Is this perfect? No. but it is how I was able to get it setup to work.

      The manual leave out quite a bit of specifics. on how to do things, but goes into detail on the technical of things.

      I don't doubt it.
      There wasn't really any added complexity though. PVE was installed with all the defaults.

      It definitely seems joined. I cannot even do anything form the IP of the second instance now.

      But it is all enabled from the primary.

      but users on your LAN need a link or some way of knowing it exists

      Users of the things running on it do not.

      If they're interacting with the hypervisor. Not like windows users. But anyone using the hypervisor would. Should have been a little clearer.

      You have that info in the thread below from the other day:
      https://mangolassi.it/topic/21751/import-a-qcow2-into-proxmox

      Basically you need to put it in the right place and it has to have the right name (depending on config file, what filesystem, VM ID)

      So the problem that I've seen from this is that it causes PM to get confused and not be able to display the storage data. Everything works, it just can't tell you where files are or delete unused space or whatever.

      Just install one of the old supported OSes on another drive, reboot and run the firmware update. It's a self extracting executable.

      With HP and Dell, it's their intention to support you by providing an additional layer of management on top of the actual manufacturers product. But you have to be in warranty to be able to leverage that support. If you intend to run equipment longer than the 5 year warranty, don't use Dell or HP or live without any firmware upgrades or support. If you use Dell or HP, replace hardware when it's out of warranty.

      HP Gen8 servers are from 2012-2013 so 7-8 years old and not the best candidates for new installations.

      @jaredbusch good point, Linux doesn't "detect non-local" like Windows does.

      ug.. what a pain that is!

      ummm wut?

      that windows detects SMB shares as remote.

      @matteo-nunziati said in Calling Debian Stretch & Mellanox Experts:

      @FATeknollogee rolling means they constantly upgrade sw when ready. The opposite is sw which sticks at a given version and is subject to security fixes only.

      Exactly. In Windows terms, it would be like MS Office updating from 2013 to 2016 automatically on any given day. Tumbleweed tends to update a couple times a week, but the updates are tiny. Just whatever applications have a new release and have been tested get released as they are ready, not in blocks together.

      The big difference is that it is updates to packages and releases of new packages as they are available, not just patches that are provided. All OSes release patches on a regular basis as needed, or weekly. But rolling releases actually update the software versions all the time.
