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 😉

@Dashrender said in Linux: Creating a Filesystem:

I'm assuming LVM will be covered separately - I'm trying to understand what it's purpose is versus just using mkfs.

It will be. And it is unrelated. mkfs and lvm do totally different things. Neither replaces the other in any way.

Who knows, everyone is pretty confused by this one.

I just used this myself to make a new block device in a single line. Awesome 🙂

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.
