Stratis is just an automation and communication layer for XFS and LVM

I did not know that.

I didn't either, was just researching it, lol. It makes it a lot more valuable, it is essentially taking the "one filesystem" advantages of ZFS or BtrFS and making them happen with traditional, mature technologies. Kind of a best of both worlds approach. Actually quite nice, if it works well.

Edit: I'm going to put my Zabbix instance on it later and see how it does.

Databases should not be compressed!

Details as to why databases should not be compressed?

Basically because they are always open and written to incrementally. They aren't loaded and rewriteen like most files are. And they tend to be very large, so a very intensive usage pattern.

True. But this compression is being done on the Host OS, not inside the Zabbix VM. I wonder what kind of strangeness this can cause. I don't have a lot of traffic on this particular server.

That doesn't affect anything. Compression is compression.

I'll find out what kind of performance hits I take with it on ZFS. So far, I'm seeing some nice space savings and no problems with anything else.

ext4 still the defaults on Debian distro as well.

Well Debian, sure. Not surprised there. Fuddy duddy distro 😉

Ya with a preallocated qcow2 I can get pretty close to raw speeds. No one is going to notice 10MB/s or even 20 in normal settings.

Right, but when you're working with files that large - why bother storing them in a VM - just st.... OK yeah, that goes against the standard practice now.. so we need a VM, even if the whole host is a VM - welp, I guess your stuck with XFS 🙂

Pretty much. EXT4 is pretty silly for a server of any size, which is why even for desktops RHEL is XFS by default and EXT4 only as an option for advanced users. EXT4's days are pretty much over.

@scottalanmiller Native in windows

Oh, well that is to be expected. You are still basically virtualizing the application. You can't reasonably ask an app to run on a non-native platform with native performance.
