Why HALizard and XenServer Failed so heavily

@scottalanmiller Which is why we're going with the standalone servers using XO's continuous replication.
-
Wow, that's crazy. Glad that it recovered.

I FTFY.

Will you still use USB sticks for boot?
-
@FATeknollogee yes, have to.
Just have to make sure we keep our backup drive current, and we're moved away from the cluster approach, and using single servers with CR.
-
@DustinB3403 "Why" do you have to?

@FATeknollogee said in Why HALizard and XenServer Failed so heavily:
@DustinB3403 "Why" do you have to?
Well, at the moment I have to see if I can create two partitions on the same array with the equipment I have.
As of last night I couldn't find a way to do it.
I have to use LVM to create the partitions needed. Yet not sure how I'll be able to do that.

For at least the fifth time... we don't make partitions here, it's volumes. LVMs make volumes. I've corrected you every time you've used the word partitions. Partitions and volumes are not the same thing.

Resize what is there. Then lvcreate what you need.

He doesn't have to, but in the emergency situation he was in yesterday, it was the fastest solution to getting himself back online.
I'm pretty sure we could get him running, this time only on the single HDD that's presented by the RAID controller.
-
@scottalanmiller ffs, volumes
Running on minimal sleep, get off my back lol...
I need 2 logical volumes one to boot from, one to hold the data, and couldn't figure out how to do it last night.

If it only creates one when you install, then you resize it to make extra space and use lvcreate to make the new volume and then add that volume as an SR.

the volumes (is that the same as partitions?) were already there. XS created sba1, sba2 and sba3. sba3 was the majority of the disk. The issue was that XS wasn't automounting it as a SR and we don't know why not. My install on a 500 GB drive mounted automatically, his 14TB drive didn't, but it was clearly seen.

I'm going to hunt you down.

Those are actual partitions, not volumes. It then makes volumes on top of the partitions.

Because it was ext instead of LVM, we are pretty sure, I think.
-
I have to start work on the host1, we can troubleshoot the issue from that unit.
Although I'd really like to just get it going with CR.. . .

That can't be it, unless it was related to size, because my SR is ext also.

OK I know what a volume is, at least for today - because of my scale, I've never dealt personally with a volume that spans more than one partition, so they've always behaved the same for me.

Very rarely do they span more than one partition. Normally one partitions holds many volumes or, as is often the case, we forgo partitions altogether.
