When using srvbuild in sybase to create the master database device and sybsystemprocs device I got the following error message: The given master device size is too
The error was so ,since, there was so much free space on the file system that it overflowed the datatype ASE used to store that value.
I created a dumb file, a very large file using dd:
dd if=/dev/zero of=/sybase-system/bigfatdumbfile.dat count=10000000000000
This solved the issue.
