- I'm looking at building a data recording system that consists of 10 channels
- each spooling data to 3 SCSI disks via 3 seperate SCSI chips... I would
- like to be able to read this disks directly on a Sun. Each disk will only
- have one file on it which is all the free space on the disk after the
- file system is laid out.
-
- Now, the options appear to be:
-
- 1) Format the disks in MS-DOS format with VxWorks and use SOS under VxWorks to
- make the disks NFS mountable on a Sun.
-
- 2) Again format the disk in MS-DOS format, but use a third party driver that
- can directly mount MS-DOS format disks.
-
- 3) Format and mkfs under SunOS.
-
-
- If I were to pre-write a file a Sun disk, is there a simple way to find out
- what blocks on the disk the file system has allocated for it. Since I
- am writing just one big file on a newly formatted disk, it should be
- contiguous (right?).
