I thought I was doing everything right, based on all the HOWTOs and such, but it's not working for me.
The DASD devices have been formatted, and I even put an ext2 file system on them (out of desperation). I can mount them as ext2 file systems, so I know they're accessible. # cat /proc/dasd/devices 0300(ECKD) at (94:0) is dasda:active at blocksize: 4096, 600840 blocks, 2347 MB 0301(ECKD) at (94:4) is dasdb:active at blocksize: 4096, 600840 blocks, 2347 MB 0302(ECKD) at (94:8) is dasdc:active at blocksize: 4096, 600840 blocks, 2347 MB 0303(ECKD) at (94:12) is dasdd:active at blocksize: 4096, 600840 blocks, 2347 MB 0400(FBA ) at (94:64) is dasdq:active at blocksize: 512, 500000 blocks, 244 MB 0401(ECKD) at (94:68) is dasdr:active at blocksize: 4096, 600840 blocks, 2347 MB Here's my /etc/raidtab: raiddev /dev/md0 raid-level linear nr-raid-disks 2 persistent-superblock 1 chunk-size 64k device /dev/dasdc1 raid-disk 0 device /dev/dasdd1 raid-disk 1 I have the linear.o module loaded, and /proc/mdstat shows that: Personalities : [1 linear] read_ahead not set md0 : inactive md1 : inactive md2 : inactive md3 : inactive The device node is defined: brw-r----- 1 root root 9, 0 Apr 1 1998 /dev/md0 But, when I issue the mkraid command, I get an error: # mkraid /dev/md0 handling MD device /dev/md0 analyzing super-block disk 0: /dev/dasdc1, 2403348kB, raid superblock at 2403264kB disk 1: /dev/dasdd1, 2403348kB, raid superblock at 2403264kB mkraid: aborted, see the syslog and /proc/mdstat for potential clues. But, there are no messages in /var/log/messages, or dmesg, or anywhere else that I can see. Anybody have any ideas? Mark Post
