[Lustre-discuss] OST fails to activate

[Dan]

Thanks a lot Andreas!!  Fixed in a second.  After a round of lfsck things are looking great.  I'm always surprised at how durable and capable the Lustre system is.  Thanks for all you effort, Lustre Team!!

I believe this is a known bug, but I can't search bugzilla right now.



The way to fix it, IIRC, is to mount the MDT as ldiskfs and delete the  

CATALOGS file.
