I need to increase the filesystem of / and /var (two different slices)? Space will be coming from /home slice so I need to decrease it. Is that possible without reinstallation or in a single-user-mode?
that is complicated, I don't have time to play with this.
On single user mode, can i umount /var and then recreate this to a bigger new slice? I might have to move some filesystem on root to be on another slice too.
If you have no space to expand your FS, I supppose you do a backup of all the partition. Recreate the partitioning using the format utility and newfs the slices again . do a restoration.. this takes time
