hi again
just for the record: this really seems to be an issue with the ar
device. i took one of the drives off from the promise controller (ar),
attached it to the onboard controller (ad) and everything works fine.
i'm cc'ing to freebsd-hackers because of this post:
http://www.geocrawler.com/mail/msg.php3?msg_id=6949487&list=159 (see
below).
now, another question: looking at dmesg i found that ar2 is also given
the device name ad7 (don't be confused by my previous post, the order of
the disks changed):
ar2: 117246MB <ATA RAID0 array> [14946/255/63] status: READY subdisks:
0 READY ad7: 117246MB <Maxtor 6Y120L0> [238216/16/63] at ata3-slave UDMA100
so i though i might use ad7 instead of ar2 but trying to use /dev/ad7
with disklabel gives me 'Device is busy' error.
please note that this is in fact no raid configuration. the disks just
appear as ar because they are attached to the promise controller.
hum... again, any hints how i could build a concatenated vinum volume
from the single ar drives ?
thanks and br,
jonas
