Bug#657843: mdcfg-utils: Wrong minimum number for RAID5 / RAID6 arrays
Package: mdcfg-utils
Version: 1.33
Severity: normal
Tags: d-i patch
Dear Maintainer,
while '3' ist a reasonable academic number for theoretical RAID5 devices,
mdadm allows to create RAID5 arrays with only 2 disks. Compared to a
RAID1, you can expand the the RAID later by adding more disks.
Similar should be true for RAID6, but I have not tested that one.
Regards,
Adrian
