Hi David and thanks for sharing your experience. However it does not bring
an answer to my question.
I personally never had problems with fixing issues and I must admit the
community is often more helpful than some commercial companies.
Since Etch I never had to reinstall my servers upgrade worked more or less
pretty well. Of course performing an upgrade on a test machine is a must.

What I want to know is if this

# blkid /dev/sdf1
/dev/sdf1: UUID="5427071b-25c8-fff8-476d-ff8c9852b714"
TYPE="linux_raid_member" PARTUUID="13e17ac7-01"
# blkid /dev/sdg1
/dev/sdg1: UUID="5427071b-25c8-fff8-476d-ff8c9852b714"
TYPE="linux_raid_member" PARTUUID="13e17ac7-01"

has some effect and I should replace one of the disks. I think the Seagate
is >10y old.
