Description Ulrich Windl 2005-08-26 07:10:37 UTC

Recent Dell servers come with an embedded SATA RAID controller (CERC SATA 2s)
which is just a dual SATA controller it seems. However in the BIOS you can set
up a RAID1 that current Linux does not recognize (it just sees two disks). From
what I've read the "dm-raid" module should be able to recognize such "RAIDs",
but SuSE Linux doesn't provide that module. I'll suggest to provide that module.
Motivation: If you have multiple operationg systems on that RAID, you can only
use that software RAID if all operating systems obey the rules.

dmraid ist shipped since SUSE 9.2 (maybe earlier). However, its idea about
partitioning is to build its own handling code which means it is not tested by
more than a few dozen users in contrast to the partition handling code in the
kernel.

Yes, I found the "dmraid" package as well, but it seems Yast doesn't try it as
part of its detection of partitions, right?

Comment 3 Johannes Engel 2006-03-01 09:26:16 UTC

Just pushing the original question: Will there be dmraid support at installation in any forthcoming openSuSE distribution?

Comment 4 Marcus Meissner 2007-04-26 12:04:22 UTC

there is support now I think.
