    Description

      Currently attempts of creating ldisk file system with size >256TB finished with message.
      "LDISKFS-fs does not support file systems greater than 256TB and can cause data corruption.Use "force_over_256tb" mount option to override."
      Before using "force_over_256tb" 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_256tb" to "force_over_512tb" should be landed. This gives ability use ldiskfs partitions <512tb without options.
