Prior to making major updates to my system, I always clone my running
system to a spare partition and verify that it boots and runs. Most
of the time this goes without a hitch, but occasionally I have
difficulty reformatting the spare partitions. I wonder if anyone
knows why.
Here''s the setup (my disk controllers are reversed hda&b are cdrom,
hdc&d are disk
/dev/hdd9 current boot partition (ext3)
/dev/hdd10 current / partition (ext3) ca. 4.4gig
/dev/hdd7 spare boot partition
/dev/hdd8 spare /partition ca. 4.3 gig
other bootable partitions on /dev/hdc
I start out by formatting the spares
mke2fs -j /dev/hdd8 no problem
mke2fs -j /dev/hdd7 fails writing superblock (something about a short
write)
much screwing around including badblock tests on hdd7 (aok)
all attempts fail
reboot and the problem disappears - hdd7 formats ok
clone completed and hdd7/8 made bootable (fstab altered, lilo
updated)
new clone boots and runs ok
Any clue why sometimes I can't remake a fs over the top of an existing
one?
TIA,
