Why do you want read only for that?
To ensure no logging goes back to the USB if it's is being actively used.
Why not just mount the FS read only if you want to block it entirely?
And how would you go about doing that, if you're using this device as a boot device for a hypervisor?
You still have to mount the volumes. Just use the read only options for your root volume, or put /var/log on a separate volume and mount it read only.

You can get usb thumb drive like things with an sd card slot. the SD card just sticks a bit out. We have a couple here.

It's called an SD card and they are very common.
No sir, that is not USB, I didn't stutter in my post! Different interface entirely.
Actually it's not. SD uses USB under the hood. It just moves the connection point. SD is the better design of USB.
SD cards survive the writes much better than USB sticks?

Will XS even boot from a read-only boot drive?

I think it would crash as it writes more than just logs to the boot device...

Right, I would think the same. So while I understand @DustinB3403 desire to keep XS from writing logs to the USB/SD card, write protecting it probably won't work.

That was just a thought, the important item here to take away is if you know of any "enterprise" grade usb's let me know.
-
Since I don't think there is a general use case for something like this, I don't know of any "enterprise class" USB sticks, or SD cards for that matter.
When you start worrying about these types of things, you replace them with SSD or HDD I would guess.

SD cards are generally higher quality, like SAS and SATA, it's convention not technology. The two are literally the same thing, just one has the adapter built on, the other does not. But SD cards have the ro/rw switch built on.

So here is one such model. http://store.kanguru.com/products/kanguru-ss3
We use them
Unless you have a VERY SPECIFIC NEED - avoid at all costs.
It's just a big, slow, exceptionally expensive USB drive that you accidently switch into RO and continually get frustrated with.

I have a 30 and 60 of these: http://accessories.us.dell.com/sna/productdetail.aspx?c=us&l=en&s=bsd&cs=04&sku=A8360320&ST=pla&dgc=ST&cid=302824&lid=5758064&acd=12309152537461010&ven1=A8360320:112781467989:901pdb6671:c&ven2=:
They're pretty nice.

I think the better question is WTF he wants clones of hypervisor boot drives for.

To protect from the chance of a USB dying.

Who cares. Install, connect to SR, move on.

Assuming you have Metadata backed up, and you have the process instructions, this really is pretty easy to do.

This may be one of those "Quantity has a Quality all of it's own" kinda situations.
Go get yourself a 4 pack of good quality drives, set all of them up and tape 3 of them to the back of your server or where ever floats your boat.
Replace annually or whatever you see fit.

He cannot, because the metadata will be invalid.
Again, the point of keeping the hypervisor on a different drive is to make replacing it simple. Simply resinstall and import the virtual machines however your hypervisor requires.
In the case of XS, you simply reinstall, point to the storage repository and then restore the last backup of the metadata. If not backup, just create a new VM and attach the disks.

@JaredBusch actually you can clone a USB from a working xs install, use the clone to boot, and just go.
No need to repoint to the storage or make any changes.
