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
