Top Forums UNIX for Advanced & Expert Users moving space from one partition to another Post 7293 by eddie on Monday 24th of September 2001 12:23:00 PM

I don't think it is possible. One partition can only be mounted to one directory. But one directory and its sub-dir can mount on several partitions. For example,

we can do this,

mount /dev/sda1 /
mount /dev/sdb1 /usr
mount /dev/sdb2 /usr/database
mount /dev/sdb3 /usr/programs
mount /dev/sdb4 /usr/other_programs
mount /dev/sdc8 /usr/programs/eddie
etc....

but we can not do following,

mount /dev/sda1 /
mount /dev/sda2 /

nor,

mount /dev/sdb2 /usr/database
mount /dev/sdb2 /usr/programs

You perhaps have allocated too much space to a partition, right? So you may have to re-partition the disk.Smilie

NAME
partition - make a partition table SYNOPSIS
partition [-mf] device [type:]size[+*] ... DESCRIPTION
Partition makes a partition table on device using the types and sizes given. It may be used in combination with repartition(8) for auto- matic installation of Minix. You may give up to four type:size[+*] specifications for the partitions. You may also specify holes before, between, and after the parti- tions. A hole differs from a partition specification by not having a type. The first hole is by default 1 sector to make space for the primary bootstrap and the partition table. The other holes are 0. The type field is the type of the partitition in hexadecimal. The size field is the partition's size in sectors. The + or * may option- ally be added to indicate that the partition must be expanded to contain any leftover space on the device or to mark the partition active. Partitions are padded out to cylinder boundaries, except for the first one, it starts on track 1. Some operating systems care about this. Minix and MS-DOS do not. OPTIONS
-m Minix only, no need to pad partitions. This is the default for subpartition tables. -f Force making a partition table even if the device is too small. EXAMPLE
partition /dev/hd0 01:16384 81:40000 81:2880* 06:20000+ Partitions disk 0 into an 8 Mb DOS partition, 20 Mb Minix /usr, 1.44 Mb Minix / (active), and a DOS partition of at least 10 Mb at the end of the disk. (06:0+ would have been ok too, it's just a sanity check.) SEE ALSO
