Hi Greg,
what if a remote volume is nfs mounted not on the vinum volume
(actually mounted on /mnt) and then a cp -r /mnt/software /raid/software/
is performed. /raid obviously being the vinum raid directory in a 1+0
configuration. This actually crashes our box. I cannot SIGKILL the cp
command and have to /sbin/reboot to restore the system.
Are there any nfs/vinum issues at present? Or am I being stupid?
I'm running 3.4-STABLE/SMP with the latest kernel tree and 2
Adaptec aic7895 Ultra SCSI adapter controllers. cvsup'd yesterday
with *default release=cvs tag=RELENG_3. I'm led to believe this tag is
correct for 3.4-STABLE but not 100% confident about that.
The drives are SEAGATE ST118273LW.
Here's my vinum.conf
darren@bod darren$ cat /etc/vinum.conf
drive d1 device /dev/da1e
drive d2 device /dev/da2e
drive d3 device /dev/da3e
drive d4 device /dev/da4e
volume raid setupstate
plex org striped 256K
sd drive d1 size 0
sd drive d2 size 0
plex org striped 256K
sd drive d3 size 0
sd drive d4 size 0
I've been reading / writing / deleting a 70 meg archive onto the RAID volume
without any problems at all. It's just NFS that causes the headache and
put it into a loop of hangs :-(
Once i've "rebooted" and try to copy files onto /raid
after the system crash, it hangs again in a loop :-(
I have no idea what or when this loop is reset.
vinum list -r also shows everything up as ok.

many thanks,
