I need some help with either `restor` or `fsck`. I'm sure this and the
solution should be on the net, as I fear all UN*X manuals probably are just as
sketchy on recovery procedures as mine are.
The dump was made with:
dump u0fk /dev/rfd1 851 /dev/rroot
And restored with:
/etc/umount /dev/rusr {dismount secondary disk}
/etc/mkfs /dev/rpf1 9728 1 64 {empty secondary disk}
restor fr /dev/rfd1 /dev/rusr {load dump of primary disk on secondary}
...then shutdown, switched disks, and rebooted...
The system booted just fine. I tried `fsck` to make sure it was OK. Fsck
got through its first phases, then (in the fifth phase, I think) said:
BAD FREE BLK COUNT
BAD FREE LIST
SALVAGE?
after an hour of trying to find someone who could confirm it, I answered:
SALVAGE? y
it did its thing and ordered:
BOOT UNIX (NO SYNC!)
it wanted no sync..fine..hit RESET and booted.
df
Oh-oh. Over 2,000 blocks free? Only had 300 when dump was taken. Did several
`ls` to see if some directories bashed. All seemed unaffected. Then again:
df
bad free count, b=7778
317
Apparently either `restor` reloaded something which was damaged on the original
disk, or `fsck` was unable to fix something which it was complaining about. It
looks like at the very least the free list is messed up.
