Hello List,
I am building a new backup box and would like to use linux software
RAID-1. But I can only afford to buy one disk right now.
Can I configure a RAID-1 array with only a single member for the time
being, and then add additional member disks at a future date?
Is is simple and safe to add additional members? I have only used the
Debian installer to configure the software RAID thus far...
Thanks, Andy
Yes,
You can build your array with the following command
mdadm -Cv /dev/md0 -l1 -n2 /dev/sda1 missing
for example
when you get another drive just partition it, and add the partition to
the array with
mdadm /dev/md0 -a /dev/sdb1 for example
