Don't need the metadata and name again after the devices

Yes, seems ok. Reboot and try to check the status of the array once again

Rebooted.
Array found, drives mounted.

So now that we're back to working condition. We need an entry added to fstab to auto-mount the array.
GNU nano 1.3.12 File: /etc/fstab LABEL=root-mhdhrpdq / ext3 defaults 1 1 /var/swap/swap.001 swap swap defaults 0 0 none /dev/pts devpts defaults 0 0 none /dev/shm tmpfs defaults 0 0 none /proc proc defaults 0 0 none /sys sysfs defaults 0 0 none /sys/fs/cgroup cgroup memory 0 0 /opt/xensource/packages/iso/XenCenter.iso /var/xen/xc-install iso9660 loo$ /mnt/raid10 /dev/md0 ext3 defaults 0 0

Does xencenter see the storage?
-
Yes, the Local OBR10 is back on XenCenter.
-
@DustinB3403 Not so sure about the entry on fstab, I don't have the entry in my setup and xen properly automounts it
-
@Romo It's outside of the norm for XenServer.
Even if it's benign.
XenServer by default, doesn't say "oh yeah go build an mdadm array" because it's not ideal if you can avoid it.

Looks good?

@anonymous besides just the two disk, yeah it looks alright.
-
Nothing wrong with RAID 1!

Will this guide work with CentOS 7?

It likely would, but you'll have to test it to find out.

To do what with CentOS 7? Do you want to install CentOS to a USB stick? Or are you just looking for the MD RAID portion?

We need to make this guide again with XS7.
