On my desktop I use Intel MatrixRAID RAID5 soft raid controller. RAID5
is configured over 3 disks. FreeBSD 8.2 sees this as:
ar0: 953874MB <Intel MatrixRAID RAID5 (stripe 64 KB)> status: READY
ar0: disk0 READY using ad4 at ata2-master
ar0: disk1 READY using ad6 at ata3-master
ar0: disk2 READY using ad12 at ata6-master
Root filesystem is on /dev/ar0s1.
Today I've tried to upgrade to 9.0.
It doesn't see this disk array. Here is dmesg. When I load geom_raid, it
finds something, but doesn't want to work with RAID:
GEOM_RAID: Intel-e922b201: Array Intel-e922b201 created.
GEOM_RAID: Intel-e922b201: No transformation module found for Volume0.
GEOM_RAID: Intel-e922b201: Volume Volume0 state changed from STARTING to
UNSUPPORTED.
GEOM_RAID: Intel-e922b201: Disk ada2 state changed from NONE to ACTIVE.
GEOM_RAID: Intel-e922b201: Subdisk Volume0:2-ada2 state changed from
NONE to ACTIVE.
GEOM_RAID: Intel-e922b201: Disk ada1 state changed from NONE to ACTIVE.
GEOM_RAID: Intel-e922b201: Subdisk Volume0:1-ada1 state changed from
NONE to ACTIVE.
GEOM_RAID: Intel-e922b201: Disk ada0 state changed from NONE to ACTIVE.
GEOM_RAID: Intel-e922b201: Subdisk Volume0:0-ada0 state changed from
NONE to ACTIVE.
GEOM_RAID: Intel-e922b201: Array started.
No new devices appear in /dev.
How could I solve this issue?
ataraid(4) had mostly read-only support for RAID5 because it doesn't
update parity data. I haven't thought anybody really using it in such
condition. That's why geom_raid doesn't support RAID5 now at all.
