You can do it right from the graphical user thing on the host.

backing up metadata doesn't look like it'll work. at least to the localhost.

is it failing?

In that case, open XC or XO and write down the label of every VM, along with the disks for each and their exact order, along with the assigned resources (RAM, CPU).
then you can manually recreated them after the reinstall, then reattach the VDIs to the VMs.
This is what I had to do when boot system died.

So VM UUID and Disk UUID (and order)
-
What about this?
Collect VM metadata and store on shared storage.
xe-backup-metadata -u <UUID of SR you want the metadata saved to>
This creates a VDI containing VM metadata. Having this metadata available speeds up VM recovery because it creates the VM itself and restores the mappings between VMs and their disks (VDIs) - Otherwise must be done manually. -
Wnen I hit backup in xsconsole it gives me an option of where to store it.

Do you have a local usb or something attached?
-
I do get a prompt of where to backup too, but local storage is the only option.

No. In fact my only option is my SR location.
Probably since the USB is having issues, maybe you can't back up the metadata?

Oh yeah, me too. I just renamed mine. Duh. (Duh on me.)

I dont even think I can migrate the VM's off.

Probably not if the boot device isn't writable.

gotta fix that issue.... some how...

Hrm, maybe try remounting root? I think this should do it:
mount -o remount,rw / -

If it's write protected to the point that it won't remount in read/write mode (what you have here), it's time to assume the storage is not recoverable.
The good news (if such a thing exists in this situation), is that restoring from XO backups is quite quick. This is what I got to deal with 3 weeks ago. XS Root drive went into a read only state, and was stuck that way even between reboots. Replaced the root drive and imported the XO backups... I used XenCenter to import the XO image itself, and then used XO to import the other backups.

We've got dc's on this host...... which means I have to do a SPX restore (since XO) isn't backing up.
