hi all,

i upgraded some extra mashine's, there wasn't any problem, when there was kernel 2.6.18 running
before, cause xen, or hardware-raid controller.

today there was a sempron 2600, adaptec, 2gb ram running latest sarge with kernel 2.6.8, root on md0
(software-raid1), lvm, all filesystem's sgi xfs.

i upgraded the minimal way
aptitude upgrade
aptitude install linux-image-2.6-k7 initrd-tools
aptitude install libfam0
aptitude dist-upgrade

it worked until dist-upgrade, download and unpacking worked and when the postinstall run's it
stopped this time at openvpn, i/o error.

running dmesg, there where xfs error's on the usr lv.

ok, started which gparted, and run xfs_check on
/ /dev/md0
/usr	/dev/vg0/usr
/var	/dev/vg0/var
/tmp	/dev/vg0/tmp

no error's on  /home, /var/log, /home, /usr/src

so all filesystem's are under higher read/write io while upgraded are damaged.
today "the best" happened on / there whas error's which was unrecoverable by xfs_repair! it fixed
all time's the same inode's. so i rsync the / over to an other machine, formated it, and synced it
back. / kept crashing before formating! mostly on shutdown.

cause this error's on /, which happened also on the machine above with ide harddisc's i think lvm
and device-mapper is not the cause.

i expect the error in xfs in conjuction with software-raid.

in all cases the error occured, where the sarge kernel 2.6.8 was still running.

are there any idea's i can do to further examine the problem?

greetings
thomas
