Building Out XenServer 6.5 with USB Boot and Software RAID 10
-
You mean
mdadm --create /dev/md0 --level=10 --raid-devices=4 /dev/sd[b-e]Need to be very certain we aren't attempting to overwrite the OS USB
-
We should also add that he needs to finish the array building before trying to add the filesystem
watch cat /proc/mdstat to see it build in real time
And also @scottalanmiller i only get mkfs.cramfs mkfs.ext2 and mkfs.ext3 as available fs by default

Yes, sorry I just copied the OP to show the order. The array needs to start with sdb, sda is the usb
-
Thats the screenshot of the array detail as you can see the array goes from sd[b-e]
-
OK Well I've directed him to this topic here, and given him the information he'll need to build the array, following the updated OP.
Lets see how it goes.
-
Don't believe it was quite ready for him yet. At least not from only looking at the OP of this thread. @scottalanmiller hasn't yet changed several things from there
-
Is mkfs.xfs not included in XenServer 6.5?
with mkfs -help I get mkfs.ext2
-
No it is not there by default best option would be mkfs.ext3
-
options found by default
-
Well that sucks. Ext3? Ugh.
-
Yeah I'm thinking he adjusted the command to be
mkfs.ext3 /dev/md0And hit enter, just waiting for confirmation.
-
Script has been updated.
-
@scottalanmiller remeber to change the line that targets devices sd[a-d] to sd[b-e],
There is also a typo in the last line,
device-config:device=/dev/md10 should be /dev/md0 following that guide -
@Romo The typo's have been addressed.

Great, this way more people can follow the guide
-
We should probably make a topic on building an off-host ISO and backup target server to complement this guide here.
Since we've already gone full tilt with the USB mdadm RAID 10....

Agreed.
-
I'm build a XenServer right now on laptop hard drives, using this guide.
So it'll tie in well with Virtualize everything.
Scott would you start a new topic with the basics of "why everything should be virtual" reference this topic, and what the "second server" will be for.
-
I wonder if it's possible to put this into a executable script that could just be downloaded, and run.

Yes it could, that's part of the goal. We want to be able to fully automate this. In the long run you will likely want a prompt that will ask which devices to add to the array and after that it could do everything on its own.
