Thanks to both Brian and Andreas for the timely responses.
Brian posed the question as to whether or not the OSTs were more or
less balanced a week ago. The answer is that I believe that they
were. Usually all OSTs report a similar percentage of usage (between
1% and 3% of one another). I

Does this mean you are using 5 2TB disks in a single RAID-5 OST per
OSS (i.e. total OST size is 8TB), or are you using 5

All,
I recently raised a question about unbalanced OSTs and received the right
answer - increase the size of the OSTs. So I set forth to do this on
our DDN controllers and rather than having 32 1TB LUNs i decided to go with

Hi all, we are running lustre 1.8.1 on about 800 clients. Some days ago, we
