This is bizarre. I just set up a Plex VM on KVM. If I pump a lot of traffic to the VM (like copying movies to it), the VM will go into a paused state.
Check the SAR report to see what the wait states are like.
Sigh... no need. I know why. I am out of space on the host drive. Stupid mistake.
How would you suggest the partition layout for the HyperVisor? I have 4.5 TB of space once the array is setup. Obviously, I'll be using LVM here.
-
One small volume for the hypervisor, maybe 12GB. Everything else in one big volume.

Yeah, so not the "Automatic partition" defaults on the standard installation....

Not normally, no.

@scottalanmiller Like so?
-
Yup
-
@scottalanmiller Good, because that's what I went with.

No worries. My family is on me asking why Plex isn't available, so I just went with it.

LOL, can't live without that VM, apparently.

When it's bitter cold outside, and it's now dark at 5:00, they need their movies.

Why EXT4?
Is there something wrong using ext4 instead of xfs besides Red Hat/CentOS using it by default?

I have the same question.

As with everything, reverse the question - is there something right about it? XFS is faster and more stable. What does EXT4 have going for it? EXT4 is not a bad filesystem, but "not bad" isn't a reason to choose a filesystem. Which one is best for your environment? I don't know any server environments where EXT4 is good enough to be considered - because it would have to be meaningfully better than XFS in some area for that to be useful.

Looks like I just need to read up on ext4 vs xfs.

Or just move on to XFS. It's a super rare case that you want anything else. Basically, always choose XFS unless you have a very clear reason to do something else. You'd have an edge case with your storage to want to even look at alternatives, and when you do BtrFS and ZFS are definitely more likely to be the case over EXT4, and JFS2, GFS2, OCFS, and others will compete heavily with EXT4.

I almost did BtrFS + XFS (Btrfs in place of LVM) on my main laptop. I still want to somewhere just to compare.

I didn't even know that it had the hooks to allow that.

Yeah, when installing Fedora, if you select custom partitioning, you can select from the dropdown to use BtrFS instead of LVM, and you can still use XFS.
