Building Out XenServer 6.5 with USB Boot and Software RAID 10

[DustinB3403]

Romo when you run

xe sr-list 

What's listed?

[Romo]

The array is now properly seen as storage in xencenter, I did have to unmount it first @DustinB3403

[DustinB3403]

What process did you run to unmount it.

[Romo]

umount /dev/md10

[DustinB3403]

So you ran

 umount /dev/md10

and then

xe sr-create type=ext device-config:device=/dev/md10 shared=false host-uuid:fba59a9c7e6db5a2d21e40343b415cfd name-label="Array storage"

Correct?

[Romo]

Yes, @DustinB3403 .

This is xe sr-list output with the array added as storage

[Romo]

@DustinB3403 sorry I did add content-type=user to the sr-create command. The final command was

xe sr-create type=ext device-config:device=/dev/md10 shared=false host-uuid:fba59a9c-7e6db5a2-d21e4034-3b415cfd content-type=user name-label="Array storage"

[DustinB3403]

OK so after saving the RAID Array (in my wall of text) he then would have to run

umount /dev/raid10

and then

xe sr-create type=ext device-config:device=/dev/raid10 shared=false host-uuid:<HOST-UUID> content-type=user name-label="Array storage"

[DustinB3403]

I'm guessing the system auto-mounted the array when you built it, and can now see it in XenCenter.

Correct?

[Romo]

It is automounting since we added it to our fstab

[Romo]

After adding the array as storage xenserver , the output of df -Th changes to this

[Romo]

I removed the /dev/md10 entry from fstab so it doesn't automount and causes conflict with xenserver handling storage

[Romo]

Xencenter after reboots properly automounts our new array

[scottalanmiller]

We need to get the UUID out of the proposed script, that much I know won't work.

Ah, good catch. I'm updating the OP with a finalized script. Please review.

[Romo]

I got the uuid using this:

madadm --detail /dev/md10 | grep UUID

[Romo]

We don't need to install mdadm, its there already

Thanks.

What is the raw output of that command? Did you need to clean it up? I want this scripted, not manual, if possible.
