I have a basic doubt:
If I have a directory whose stripe size is default and stripe count is set to 1. I have thousand files in that directory.
Total number of OSTs in my Lustre file system is say 8. Then how are those thousand files written to the OSTs?
Is it that first one OST is filled up with as many files as possible and then next OST is targeted or is it like file 1 to OST 1, file 2 to OST 2 and so on and then it comes back from file 13 to OST1.

Please help.

Thanks and Regards,
