sarge2etch upgrade destroys xfs filesystem on lvm2 over md-filesystem

Thu May 31 10:03:23 UTC 2007

hi all,

i have new information.

the problem comes up, in the moment, the old kernel - i am not sure, if it only occurs  with 2.6.8
from sarge, hadn't currently no other - is running, new mdadm package get installed and write-access
to disc is done.

so one solution is:
modify apt.source to etch
aptitude update; aptitude upgrade
aptitude install aptitude install linux-image-2.6-??? grub aptitude
sync
aptitude install mdadm

check if /boot/initrd-2.6.18 is correct created (cause possible problems on /tmp which is a separate
xfs-filesystem)

run update-grub and reboot

now run aptitude dist-upgrade

i the meantime i thought the problem  occurs, cause or partition scheme:
part1	(md1)  /boot
part2	(md0)	/
part3	(md2)	pv for volumegroup
part4	---	swap

cause once i had the problem, where mdadm swapped md0 and md1, but the first machine had the
partition's and md-devices in the same sequence.

maybe this helps
