- newdisk automator
- This program can be used in two mode: automatic and manual.
- Automatic:
- newdisk-automator [-f] device
- device is partitioned according to the following scheme:
- - calcolo: 100GB
- - swap: ram size + 1GB
- - free space: 10% of the total
- - condor: 40% of remaining space
- - tempdir: 60% of remaining space
- If the size of the disk is less than 102GB + ram size, this mode cannot be used.
- If the size of the disk is greater than the minimum size, but still less than (100GB + ram size) * 2, to use this mode the -f option must be passed.
- Be careful: in the automatic mode, calcolo and swap size are fixed, and forcing it with -f could result in having very small tempdir and condor partitions.
- Manual:
- newdisk-automator device temp_size condor_size swap_size vm_size
- The partitions are assigned the size passed on the command line. b, K, M, G can be appended to the sizes for bytes, kibibytes, mebibytes and gibibytes. The default is bytes.
- If the total passed with the command line is greater than the size of the disk, the program stops.
