Hi!
Hoping that some kind soul can help me with this:
I've 3x RZ57 on above mentioned System and tried to create a stripe set
over those HD's.
"raidctl" gives this back:
bash-2.04# raidctl -v -C /etc/raid0.conf raid0
raidctl: unable to open device file: /dev/raid0c
The device files /dev/raid0c and /dev/rraid0c do exist.
The raid control file "raid0.conf":
--------------------------
START array
1 3 0
#
START disks
/dev/rz2c
/dev/rz3c
/dev/rz6c
#
#START spare
#
START layout
# sectPerSU SUsPerParityUnit SUsPerReconUnit RAID_level
64 1 1 0
#
START queue
fifo 100
#
------------------
Is there something missing or wrong. I'm not sure about this "sectPerSU"
number.
All the RZ57's are disklabeled like this:
------------------------------------
bash-2.04# disklabel -i -I rz2
partition> P
8 partitions:
# size offset fstype [fsize bsize cpg]
a: 65536 0 unused 1024 8192 # (Cyl. 0 - 62*)
b: 151552 65536 swap # (Cyl. 62*-206*)
--> c: 1954050 0 RAID # (Cyl.
0 -1860) <--------
d: 299008 831488 unused 1024 8192 # (Cyl.
791*-1076*)
e: 299008 1130496 unused 1024 8192 # (Cyl.
1076*-1361*)
f: 524546 1429504 unused 1024 8192 # (Cyl. 1361*-1860)
g: 614400 217088 unused 1024 8192 # (Cyl. 206*-791*)
h: 1122562 831488 unused 1024 8192 # (Cyl. 791*-1860)
partition> Q
bash-2.04# exit
----------------------------------------------------------------------------
-----------------
RZ3 and RZ6 are labeled accordingly.
There are some more raidctl commands needed to create the stripe set
finally. What is the exact sequence of those commands.
Thanks a lot in advance and best regards.
