Might need to migrate to my backup server (14.9TB) and rebuild this host.

What is it you are trying to recover? Is this a database?
XS host.
How did you find the error?
-
XO backups were failing, researched the error and then found it. (xenserver forums)
-
I may have to migrate the VM's to my backup host and then rebuild this host...
-
Reboot host and see if that fixes it?
How many bad inodes did it find?
-
@dafyre What are the chances that the server won't restart properly?

It shouldn't considering it's no longer kicking back errorsJust saw the amount. Def taking this one back.

If it found just a few bad ones, it won't be a big deal, but if it found a lot, yeah, I'd live migrate the VMs off before rebooting, lol.

Yeah I didn't know it was that fargone. That's a lot.

Is the boot drive on the same drive as the VMs?
-
@BRRABill Good point. I thinks he's booting from a USB. Couldn't he rebuild on a new USB and then reintroduce the existing local storage?

I was thinking that would be a lot easier to try than migrating 14TB of data.

Yes the boot device is USB.
I can do this, assuming the underlying storage is reliable enough.
Any concerns or recommendations on doing so?
I'd be introducing the existing SR's back into the USB xs install.

Why would the underlying file system of the VM storage come into play? Isn't it the boot (USB) that is having the issue?

you have to adopt the SR back into the new install, and if your meta data isn't restored, you have to manually rebuild all of your VMs from the VDIs.

Ok so there is two questions here.
First - meta data backup. I know you've done this before. Got instructions lying around?
What gotcha's are needed to backup?

Yeah but the host is still up he can take a backup of that still.
Either through XC or the CLI.

XO backups are not operational at moment.
