Testing out KVM with .qcow2 on Gluster. Rather than mounting the GlusterFS over the network, I'm running Gluster on the hypervisor. That way I have local storage for the .qcow2 file, but it's replicated over the network to the other node. Just want to see how it works.

That is an interesting thought. I'd be interested in hearing how well that works.

I'll let you know. It's on two ancient HP DL165's from like 2005, and has an old AMD. I'm not 100% sure that they have full hardware virtualization so I don't know how real world this test will be haha.

A DL165 from that era should not. It is almost certainly disabled We have a DL145 G2 and DL145G3, both from that era, both disabled.

I figured. I went into the BIOS and enabled the SVM or whatever theirs is called. Qemu still hit 110% during the install though, so there must be a lot of software emulation going on. On the plus side, Gluster only used 3% of CPU (during the install). Load only hit 1.4 on an 8 core system.

It should work good enough to provide some good testing, it seems.
-
That should be an interesting test.

You should tell him if it starts with 192 it's Windows. If it starts with 10 then it's a Mac.

So I did some testing. No internet access on that network, so I did some very scientific write tests of dd'ing /dev/urandom and /dev/zero to a file. Was pretty slow, but I'm pretty sure that's because of all of the software emulation going on. However, the main thing I was interested in was the replication.
I made a couple new files in the VM. Shut it down on the first node, and booted it on the second. Everything was there. Didn't try to configure any auto-failover. But This was 100 times easier to set up than manually setting up DRBD.
-
Oh yes, Gluster is way easier than DRBD.

I think it makes more sense if you're just using image files for your VMs. If you're using LVM for a backing store then I guess DRBD would make sense (like with XS) but Gluster makes more sense in my mind for image files.

I equate Gluster being more of a replicated SAN than I do DRBD... Although I know they both accomplish the same thing, just in different ways.

I think Ceph would be more of a replicated SAN and Gluster would be more of a replicated NAS.
By default that is. You can use Gluster for block storage. You can use CephFS but from what I've seen its not really ready to be used (haven't tried it).

Just wrapped up D&D night.
-
Trying to not freak out that I've been up since 4AM yesterday (1:20AM currently here) and I have to be at work in 40 minutes...and work til 8AM...to which I will come home and crash HARD!
-
Good morning everyone!
-
I must be catching up on sleep. Just slept for nearly ten hours.
Last night did some introducing of my kids to Full House. The five year old is okay watching it but doesn't really care. But the seven year old absolutely loves it.

Thinking do I read up on trouble shooting SQL performance or leave it to the "experts" and keep waiting lol
