 Description   

Currently attempts of creating ldisk file system with size >512TB finished with message.
"LDISKFS-fs does not support file systems greater than 512TB and can cause data corruption.Use "force_over_512tb" mount option to override."
Before using "force_over_512tb" parameter in production systems lustre file system software should be analyzed to point possible large disks support issues. This issue is about research of some aspects of Lustre software. Finally patch that change "force_over_512tb" to "force_over_1024tb" should be landed. This gives ability use ldiskfs partitions <1024tb without options.
