[linux-lvm] alpha 2.4.2 + 0.9.1_beta6

[linux-lvm] alpha 2.4.2 + 0.9.1_beta6

[Andrejs Dubovskis]

Hi,

unfortunately, for my environment LVM subsystem does not look stable.
AlphaServer AS400
Redhat 7.0
2.4.2 + LVM 0.9.1_beta6
2 SCSI disk

pvcreate /dev/sda1
pvcreate /dev/sdb2
vgcreate vg01 /dev/sda1 /dev/sdb2
lvcreate -i 2 -I 8 -l 2040 -n sms vg01
mke2fs -m 0 /dev/vg01/sms

All test was done in single mode (no network, users, daemons, etc).

boot system in single mode 

vgchange -a y
mount /dev/vg01/sms /opt
dd if=/dev/zero of=/opt/1 count=10000
dd if=/dev/zero of=/opt/2 count=100000
dd if=/dev/zero of=/opt/3 count=1000000
(dd commands' count every next boot may be different)
Got kernel panic in interrupt handle.

boot system in single mode again

vgchange -a y 
Got kernel panic in interrupt handle (not reproducible at next boot).

Best regards, Andrejs Dubovskis

Sorry, can't help you if you don't include ksymoops output (or at least
some more specific problem description).

Need ksymoops info as well.  I don't have any non-ix86 systems to test on,
but at least we should be able to narrow down the problem a bit.  Note
that Andrea Arcangeli does test LVM on Alpha, so I'm surprised there are
major problems.  However, it may be that he has Alpha-specific patches
in his LVM code that are not in the standard LVM sources.

Cheers, Andreas
