Hello all, We're looking for Best Practices regarding setting IOPS and Throughput limits on "Hard Disks" in proxmox. There's obviously limit and brust settings under Advanced on a given disk. Questions we have: Is there a way to see, from the Host level, the current IOPS/Throughput a...

This worked for me too thank you!! (had to restart after too, or only worked with rbd tool in cli)

So we had this problem again, with the same setup as described at the start of this thread, but while live migrating a VM that didn't have discard set :/ The only thing I could find worth noting was that this VM did not have "format=raw", as mentioned in the bug referenced above. What happened...

Any luck?

I get it. But that's what we did, and we've been good since. Plus the kernel change of course.

Did you follow all the suggestions earlier in this thread? I haven't had any issues since I reported things were fixed a while back.

We have ZFS for proxmox OS, and then a separate volume for VMs. We're not using LVM, but rather just ZFS, which I believe simply supports thin provisioning (otherwise we would see the storage usage shrink when we "fstrim -a" when discard is set).

This was very helpful. Thank you!

Good to know. That said, is there a certain percentage of frag that I should monitor for, that way I don't have to find out when customers start complaining about performance issues?

When should you worry? I have 40% on SSDs. Any way to know, before it gets us in a pinch?

Awesome! Thanks for the update.

Hey, ya I have just been disabling the discard flag (requires reboot though of course) if I need to live migrate. I'm not sure what the fix is. Perhaps it has been fixed in a newer release. I suppose one of us should submit a bug ;)

If you read around page 1 and 2, you'll find the answer to get the VMs to start.

Ah thank you, I will try that out. That said, are you able to confirm you see similar bandwidth issues with speedtest-cli?
