Building Out XenServer 6.5 with USB Boot and Software RAID 10
-
We can also use the whole disk, without the need to create partitions in them, don't really know if this is better but it is a possibility.
This is the screenshot of the raid array created with 4 disks using the whole disks.
-
@DustinB3403 Yes, I couldn't create the md10 device in my setup without loading the modules into the kernel
-
@Romo correct, that's part of the purpose of the new guide, to use the whole disk rather than to partition it first. Fewer steps, better results.
-
This shows the file system added to our raid array
-
Automounting
-
mdadm.conf
-
Checking filesystems present in our system, at the bottom theres our array.
-
And finally the status of our array
-
@Romo -- sd[b-e]... Is this your boot drive, or just the data stores for XenServer ?
-
That is the data store.
sda would be the boot device.
sd[b-e] would be every other disk in the system available.
-
Without anyone outcrying (@scottalanmiller and @Romo) are we settled on providing the above process to configure mdadm on a USB XenServer?
-
Yes, just need to compile it into a step by step "one place" list.
-
And it would be handy to know what his device list was going to look like.
-
And preferably test it as you go, lol.
-
Does anyone know how to select the VM storage in xenserver, outside of the ISO installation process. We probably need that as well.

@DustinB3403 I am actually trying to do exactly that just right now on my test setup. It thought that with this command:
xe sr-create type=ext device-config:device=/dev/md10 shared=false host-uuid:fba59a9c7e6db5a2d21e40343b415cfd name-label="Array storage"It would get added as local storage to xencenter, but I am getting this error :
The SR operation cannot be performed because a device underlying the SR is in use by the host.Don't really know why, I haven't used xenserver before. Any ideas @scottalanmiller
-
OK so without the specific target device I believe this command will work.
xe sr-create content-type=user type=ext device-config:device=/dev/cciss/c0d0p3 shared=false name-label="Local storage"
We simply need to determine his device path

The reason your target device is in use is you have it mounted. Try dismounting the array and try again.

Romo when you run
xe sr-list
What's listed?
