Hi,
I'm just testing how well the upgrades do work and somehow I have a problem:
On Ost1:
========
[ 271.985901] LustreError: Trying to start OBD lustre-OST0001_UUID using the
wrong disk ost1_UUID. Were the /dev/ assignments rearranged?
Well, that's the problem. Note the uuid is missing from the tunefs on
the OST, but not the MDS.
This a safety check to make sure you're using the right disk; it should
have been found when you did the initial tunefs upgrade to 1.6.
You can erase the last_rcvd file manually out the of OST disk to get
around this.
