What does this mean?

[Michael Paul]

    Hi there...

 I get the following message when cat'ing /proc/mdstat:

md0 : active linear [dev 08:30] [8]  [dev 08:20] [7]  hdj[6]  hdi[5]  hdh[4]
hdg[3]  hde[2]  hdc[1]  hdb[0]
182485184 blocks 4k rounding

 In my raidtab file, sdc = 7 and sdd = 8. Is there some type of error here?
The linear seems to be working properly, but since I'm such a newbie, I
can't tell for sure. I wish there was a better way to check on the raid
status.

Thanks,
Michael

                           ^^^^^            ^^^^^

Well, you're in luck, because these numbers are the major and minors for
sdc and sdd:

$ ls -l /dev/sdd
brw-rw----    1 root     disk       8,  48 May  5  1998 /dev/sdd
$ ls -l /dev/sdc
brw-rw----    1 root     disk       8,  32 May  5  1998 /dev/sdc

(hex 20 and 30 => decimal 32 and 48)

I'm not sure why md sometimes puts the major:minor instead of the device
name. Perhaps has something to do with the driver for your sdc and sdd?
I'm guessing here...
