Hello ,
Just a questune , does single file stipes across few OTS's ?
I just run into strange behviour of lustre , i tested the way lustre stipes the data on 2 OST's
There are 2 OTS's
1 is 5 gig with 50% left
2 is 3 gig with 90% left on it
Im moving 3 gig file to lustre(from a client)
it start wrting the file to OST 0 as it say on lfs getstripe filename.iso
while the file is moving im watching the OST 0 with df -h 
OST 0 is starting to fill up and when getting to 100% the file transfer is stopping with an error
I had the imression that it will continue wrting the file to OST 1 when OST 0 run out of space 

Is this behaviour is ok ?

Thanks ,
