Proxmox 8.0.2, turnkey templates were missing, and this worked for me: # pveam update

Quick note on the LSI SAS-9211-8i with IT firmware, I have about a half dozen of these in use for the last 5 to 6 years with zero issues. In a couple dev machines I hang SSDs off them, 4 drives max, with zero issues from the card. Other machines have 8 HDDs in them, all with zero issues from...

Thought I'd check :) In reading through all your posts the performance issues existed when those restrictions were not present. So only now realizing that removing those restrictions likely will not have an impact. But, my instincts say that a lot was changed so may want to retest by...

No simple answer because it all depends on your objectives and hardware constraints. Do you have full PCIe 3.0 x16 slots open? How many? Are they restricted when using onboard M.2 slots or SATA ports? Are they bifurcated or non-bifurcated? You want to use M.2 NVMe drives or 2.5" NVMe...

iops_rd=4500,iops_rd_max=5000,iops_wr=4500,iops_wr_max=5000, I never modify these so no idea what is reasonable, but do all the VMs have these restrictions set? If so, have you tried removing these restrictions? Do you have the same restrictions set on your "home" machine? Clear this with...

On the working days ( mostly Thursdays and Thursdays ) the system would get slow starting arount 12 and from ~15:00 would be to slow to work at all and we would get complains from everyone. Do you have backups scheduled at this time?

I know zero about your environment and depending on how "affordable" you want, look on ebay for Intel DC SSD drives. These are datacenter rated drives and unless they were seriously abused, likely you'll never wear them out. Ask the sellers to send you the SMART data and confirm the drives are...

My own experience with write performance on SSDs that have a capacity smaller than 128G is they suck really really bad. A couple cheap consumer grade SSDs that I own which are 64G write about 512MB then lock up the entire system until the entire write finishes and the sync closes. They are...

What steps did you follow in this upgrade guide? https://pve.proxmox.com/wiki/Upgrade_from_4.x_to_5.0 Specifically, the Introduction section that says, "you'd better empty the browser's cache after upgrade and reload the GUI page or there is the possibility that you see a lot of glitches."?

Who is going first?

Do you have an error message in the task area or in the backup job? Also, what version of Debian are you running? Stretch (v9)?

When will the patch be ready for download?

Is there an ETA for a fix or a valid workaround? I've tried switching between SCSI and virtio, enabled/disabled writeback, and tried other suggestions in this forum still broken. This starting to become an issue for us because now about 80% of our VMs won't restart after backup. I can provide...

Is there a fix for this yet? I have VMs all over the place that are not starting and no combination of virtio or SCSI is solving the issue. - TASK ERROR: start failed: org.freedesktop.systemd1.UnitExists: Unit 123.scope already exists. This is starting to become a big problem for us...

Might clear the browser cache too. More tidbits for upgrading: - https://pve.proxmox.com/wiki/Upgrade_from_4.x_to_5.0

I don't know why they would, but I'll leave the official answer to the proxmox support. What boot mode are you using and how did you set the SATA devices? Are you using legacy boot mode and AHCI SATA by chance?

"So would the fastest thing be to reinstall the usb" I read somewhere you need to set the boot delay to a minute so the LVM can start up if you insist from running Proxmox off a USB stick, but I'm not sure if that is the case or not. Generally it is advised against running Proxmox from a USB...

That and we tend to include SSD drives either as cache or use SSD drives for the entire data store these days. I didn't read closely, but curious of they enabled compression on ZFS. Really though, while good to see benchmarks, storage is finding the right balance between capacity, performance...
