Comment 13 for bug 356503

Hello, I am experiencing similar, but maybe not exactly the same problem.
I just upgraded fron 8.10 to 9.04 and cannot access my fakeraid disks with dmraid.
I tried following:

sudo dmraid -ay

RAID set "isw_eagedjaiic_Volume0" already active
ERROR: dos: reading /dev/mapper/isw_eagedjaiic_Volume0[No such device or address]

sudo dmraid -s
*** Group superset isw_eagedjaiic
--> Active Subset
name : isw_eagedjaiic_Volume0
size : 1953536512
stride : 128
type : raid5_la
status : ok
subsets: 0
devs : 3
spares : 0

This looks similar to your problems so I tried following:

sudo dmraid -an
ERROR: dos: reading /dev/mapper/isw_eagedjaiic_Volume0[No such file or directory]

sudo dmraid -ay
ERROR: device-mapper target type "raid45" is not in the kernel
RAID set "isw_eagedjaiic_Volume0" was not activated

This raid set was working fine couple of hours ago on 8.10...
Now I am a little bit sad missing my data ...
