Hello all,

I'm having a serious problem with vinum and ccd. I have four 80GB drives
connected to a supermicro 370DER. I can do a newfs on each drive at the same
time without any problems, but trying to build a stripeset causes the
machine to hang horribly.

First I tried vinum with the following conf

drive d1 device /dev/ad0e
drive d2 device /dev/ad1e
drive d3 device /dev/ad2e
drive d4 device /dev/ad3e

volume backup
plex org striped 256k
sd length 78159m drive d1
sd length 78159m drive d2
sd length 78159m drive d3
sd length 78159m drive d4

Everything looked ok, made a newfs and mounted /dev/vinum/backup. I wrote a
80MB file, ok. I wrote a 800MB file system hangs without any dump.
Same with fsck. If I fsck /dev/vinum/backup the system hangs.

I decided to take ccd, but it was exactly the same.

Here what dmesg says:
ad0: 78167MB <Maxtor 98196H8> [158816/16/63] at ata0-master UDMA33
ad1: 78167MB <Maxtor 98196H8> [158816/16/63] at ata0-slave UDMA33
ad2: 78167MB <Maxtor 98196H8> [158816/16/63] at ata1-master UDMA33
ad3: 78167MB <Maxtor 98196H8> [158816/16/63] at ata1-slave UDMA33

Fdisk set the geometry to 9964/255/63

What am I doing wrong?

Thanks,

- -Harry
