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 / -

mount -o remount,rw //devb/sdb1 read-write is write-protected.
So how do I remove that?

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.

And a f***ing massive file server.

Any chance you previously saved the metadata to your SR?
-
Sorry you are going through this.
Especially on a Friday night.
-
Im going to start an restore from the 21'st to my second host, which is running fine. And then we'll have to do file level restores from there....
For the DC going to have to bring in our MSP.....
F**** [moderated] XenServer why do you hate me so much.
Why has my original XS host run fine (literally like a f***** [moderated] dream for 2 years) and these two hosts are giving me issues....
what the f**** [moderated]!

I was afraid of this.

I can however restore my backups from 6 days ago to my remote host, and inside of the VM's boot from SPX recovery environment and restore from there.

@DustinB3403 Or a clone / image of the USB?

Nothing recent enough to try I don't think. I do have a clone of this USB though.
-
@Danp from 6-21-2016.
f****ing bullpucky[moderated]... cause "we can never have these servers down"
Well how the f*** *[moderated] do you expect to do maintenance or anything on them?!
-
Hold on dude..
your data is still probably just fine..As long as XC still works, pull the data i mentioned before - find all the uuid's from all drives and their mounted order to each VM and write it down.
then you'll shut down the server, replace the USB drive, then install XS then install updates,
then attach SR
then start remaking your VMs by hand and attach your VDIs to the VMs and boot -

Make another copy and then boot from that. What's the worst that could happen?
-
Yeah I would definitely try...
- booting from your cloned USB
- reinstalling XS and recreating your VMs by hand as Dash has suggested
- doing a restore
In that order.
I played with XS a lot moving the boot drive and stuff and it was pretty resilient.
