I didn't know that, sorry. I'll let you know how it works out when it
craps out next time.

But I noticed something interesting when I was playing around with it.
There were 5 processes in the kernel doing something with the defunct
xfs mount, which is no surprise, and when I tried to run xfs_repair
and straced it and there was nothing that looked like a scan of kernel
objects (e.g. via /sys). But I've noticed a call to ustat on the newly
connected device, which had a different ID, the disconnected one was
/dev/sde103 and the new device (the one ustat-ed) was /dev/sdd103, but
ustat reported it mounted. Does XFS do this?
