Durring an install of CentOS 6.4, I see two locations where I can select "Allowable Drives"
The first time I select "Allowable Drives" is to select which drives are added to my fstab. That makes sense, and I have no questions there.
The second time I see "Allowable Drives" is while creating a partition.
According to the description
Allowable Drives: This field contains a list of the hard disks installed on your system. If a hard disk's box is highlighted, then a desired partition can be created on that hard disk. If the box is not checked, then the partition will never be created on that hard disk. By using different checkbox settings, you can have Disk Druid place partitions where you need them, or let Disk Druid decide where partitions should go. http://www.centos.org/docs/5/html/5.2/Installation_Guide/ch04s18s05.html
I am adding an ext4 partition to disk sdb. I have gone through the partitioning several times, experimenting with checking sdb, sdb and sdd, and just sdd
So far, the partition is created correctly regardless which drive is checked in this box.
Can someone enlighten me what these options are supposed to change?
