@olivier NP... I know it's isn't within your control. 🙂

And patch management and software updates are taken care of for you.

@r0dISK said in I did a thing, have a quick Linux question:

22TB ? mdadm + RAID6...

That's a lot to have under RAID 6, but for a home lab is fine.

Good information for me as I'm in the process of learning XenServer (although its 7)

And VMware marketing in 3...2....1....

Brilliant Read, I've used Esxi and Hyper-V, good products, but I do have a inner love for Xencenter..

Does the VM I want to work from need to be offline?

When attaching the disk? yes.

why? You can add new disks to VMWare while a VM is running without any issues. I'm pretty sure you can attach a pre-existing partition as well.

You can do the same in XenServer. At least with Windows as the guest. I haven't tried it with Linux.

You can't however do this if the source drive is running on a separate VM. (That VM must be powered off).

Which is what I did in order to do this.

Right, unless you unmount the source drive first. I don't even think VMWare can reliably do this.

VMware can do it reliably on its side, but it would still hose the data inside the drive.

Right, unless it's a cluster aware OS and Filesystem.

Just cluster aware filesystem. GFS2, OCFS, VxFS would all work fine.

Open an issue and ideally send a PR with the fix: that would be your first (easy) contribution to the project 🙂

@scottalanmiller said in Thin provisioning in XS7:

And if you look, that EXT3 type is on LVM. Hence the weird confusion 🙂

Yeah that, as I said, is what got me.

So, if you pick EXT is enables thin provisioning by default?
Yes. Because thin provisioning is not actually the option. It's actually just raw LVM vs file based. Files are thin provisioned. LVM raw is not. File based is being called ext3 here.

@dafyre said in Linux: The Role of DRBD:

@scottalanmiller said in Linux: The Role of DRBD:

I added a header into the main topic list for that. But it is going to be later in the Advanced Topics, section. Oddly, I know of pretty much no standard Linux Administration tomes that cover DRBD. It's so core, very odd that it so often gets missed.

Could it be that most Linux Admin's don't know about it until they go searching for it? ...That's how I found out about it.

You would hope that the people writing the books would know, though!

@hobbit666 said in Unitrends Enterprise Backup and XenServer 7:

AHHHHHHHHHHHH!!!!! Can't restore a VM Backup that was done on ESXi onto Hyper-V! only another ESXi.

Do you need the entire backup of the machine? You can mount the image of the backup and restore any files anywhere you want.

I actually used XO to migrate the VM that XO was running on.

Now THAT was cool!

Xen XAPI api is not running on this .... F8 to try and start it.

So I cloned on a system that isn't critical, and when I try to boot off of the clone that is what I get.

Any ideas?

As to a two-sever pool, interestingly Ive been working with SC at HA-Lizard over the last few weeks and we've come up with a better way (I think) to support a two-server pool. I've done a lot of torture testing and think there will be a more robust implementation in the near future. I'm particularly interested in that we now have several two-server pools and there is no need to expand just for the sake of supporting HA. Stay tuned for more news on this! For HA to work, you'd still of course need shared pool storage.

@halizard Awesome, I'll have to give it a whirl.

Have you guys done any testing? Would like to hear what improvements you guys are seeing.

I know a guy who built his own blade unit. Wooden blade enclosure and some simply power supplies and his own fans, then made it allow straight motherboards to slide in so that it make having a handful of systems running in a cluster super cheap. Pointless for production, but for a lab was very interesting.

I'm sure NSC Global would support it
