Then you didn’t understand how the system uses swap.

I think that’s illegal in some places, like California and the EU.

Weird I still see the comment. I wouldn’t even know it was deleted if you hadn’t said something.

Looks like wireguard encrypts traffic to me.

Not really. They need FF to exist to avert monopoly accusations.

I just wanted to say I loved your analogy.

I’ve been happily running Open Media Vault in a Proxmox VM for some time now.

SeeJayEmm, 12 days ago

I didn’t pass any phy disks through, if that’s what you mean. I’m using that system for more than OMV. I created disks for the VM like I would any other VM.

I would start by making sure you have good recent backups ASAP.

I do.

Could be as simple as a service logging some warnings due to junk incoming traffic, or an update that added some more info logs, etc.

Possible. It’s a really consistent (and stark) degradation in performance tho and is repeatable even when the opnsense VM is the only one running.

While you’re waiting for that, I’d also look at the smart data and write the output to a file, then check it again later to see if any of the numbers have changed, especially reallocated sectors, pending sectors, corrected and uncorrected errors, stuff like that.

That’s a good idea. Thanks.

It’s an old Optiplex SFF with a single HDD. Again, my concern isn’t that it’s “slow”. It’s that performance has rather suddenly tanked and the only changes I’ve made are regular OS updates.

SeeJayEmm, 13 days ago

I’m trying to think of anything I may have changed since the last time I rebooted the opnsense VM. But I try to keep up on updates and end up rebooting pretty regularly. The only things on this system are the opnsense VM and a small pihole VM. At the time of the screenshot above, the opnsense VM was the only thing running.

If it’s not a failing HDD, my next step is to try and dig into what’s generating the I/O to see if there’s something misbehaving.

SeeJayEmm, 13 days ago

I’m starting to lean towards this being an I/O issue but I haven’t figure out what or why yet. I don’t often make changes to this environment since it’s running my Opnsens router.

I thought cheap SSDs and ZFS didn’t play well together?

SeeJayEmm, 13 days ago

I may end up having to go that route. I’m no expert but aren’t you supposed to use different parameters when using SSDs on ZFS vs an HDD?

SeeJayEmm, 12 days ago

Thanks for all the info. I’ll keep this in mind if I replace the drive. I am using refurb enterprise HDDs in my main server. Didn’t think I’d need to go enterprise grade for this box but you make a lot of sense.

SeeJayEmm, 12 days ago

This was really interesting, thanks for the info.

SeeJayEmm, 11 days ago

I’ve done a bit of research on that and I believe upgrading the zpool would make my system unbootable.

SeeJayEmm, 11 days ago

Proxmox is using ZFS. Opnsense is using UFS. Regarding the record size I assume you’re referring to the same thing this comment is?

You can always find some settings in your opnsense vm to migrate log files to tmpfs which places them in memory.

I’ll look into this.

SeeJayEmm, 11 days ago

I’m referring to this.

… using grub to directly boot from ZFS - such setups are in general not safe to run zpool upgrade on!

Unless I’m misunderstanding the guidance.

That cheat sheet is getting bookmarked. Thanks.

SeeJayEmm, 11 days ago

Media should exist in its own with a tuned record size of 1mb

Should the vm storage block size also be set to 1MB or just the ZFS record size?

SeeJayEmm, 9 days ago

Thanks I may give it a try if I’m feeling daring.
