It never detected my second hdd correctly and that at several occassions.
That behaviour would have been "as designed" or more correctly "as not designed".
There is specific guaranteed behaviour, but beyond that the outcome is indeterminate.
There are Howtos that advise the right way to add a second drive:
http://wiki.contribs.org/AddExtraHardDiskhttp://wiki.contribs.org/AddExtraHardDisk_-_SCSIRelease notes indicate the drive setup possibilities.
See these from sme7.0.
Automated RAID installation
NOTE: All disks must be the same size for SME Server 7.0
- Single disk provides one-way RAID1
- Console screen allows simple addition of second disk to provide mirroring
- Two disks are configured as a RAID1 mirror
- Three to five disks are configured as RAID5 (/boot partition is RAID1)
- Six or more disks are configured as RAID6 (/boot partition is RAID1)
From sme7.2
Disk redundancy
---------------
- The default disk layout has changed. A hot spare drive is
automatically created if the system has more than two drives.
A new boot option "nospare" has been added if you are certain that
you do not want to create the spare. You should only use this option
if you are aware of the consequences of running without a hot spare.
- Errors from add_drive_to_raid are now displayed in the console
- Adding drives with invalid partition tables now works without a reboot
- Attempts to manually add RAID devices to systems without RAID shows an
error
sme8 uses similar/same design concepts (allowing of course for changes that the newer underlying OS supports).
