raidreconf on linux sparc64

(Please keep me on the CC, as I'm not subscribed to this mailing list)

As I was testing software raids on linux sparc64 with 2.6 kernels[1] for the Splack distribution[2] I noticed that raidreconf won't work. I did try to look at the problem, but I'm afraid my skills won't go there.

My old raidtab[3], is a raid0 with only two drives, and I'm trying to get it to that the new raidtab[4] has, wich is the same raid0 but I added four more drives. When I run "raidreconf  -o oldraidtab -n newraidtab -m /dev/md0", I get "Your on-disk array MUST be clean first". I googled, but it had only happen to one guy, and it had been adviced to stop the raid (mine is stopped).

Any clues? Is it a sparc64 thing?

Ohh, I did tried with a 2.4.26 kernel as well, with the same result.

[1] The hardware is an Enterprise 250 with one processor, 256M or ram, 6 scsi drives splitted among two controllers running a kernel kernel 2.6.6 compiled with gcc 3.3.3 (from gentoo).
[2] Slackware for sparc port.
