what's fstype 83? "Linux"?

[will trillich <will@serensoft.com>]

i've found an old (debian slink?) drive around the house, and
plugged it in -- but i can't mount most of the partitions!

	root# sfdisk -l /dev/hdb

	Disk /dev/hdb: 4956 cylinders, 16 heads, 63 sectors/track
	Warning: The partition table looks like it was made
	  for C/H/S=*/128/63 (instead of 4956/16/63).
	For this listing I'll assume that geometry.
	Units = cylinders of 4128768 bytes, blocks of 1024 bytes, counting from 0

	   Device Boot Start     End   #cyls    #blocks   Id  System

yes, i know, that's an awful place for the swap partition. i
know, i know. i'm feeling much better now -- this was a few
years back, when i set this puppy up. it sure would be nice to
mount it and recover the things i'm interested in...

i'll try mounting partitions hdb1, hdb2 and hdb5:

	root: /mnt# mount -t ext2 /dev/hdb1 /mnt/1/
	mount: wrong fs type, bad option, bad superblock on /dev/hdb1,
		   or too many mounted file systems

hmm! maybe if i leave off the trailing / no the mount-point--

	root: /mnt# mount -t ext2 /dev/hdb1 /mnt/1
	mount: wrong fs type, bad option, bad superblock on /dev/hdb1,
		   or too many mounted file systems

nope. let's try partition 2 for fun:

	root: /mnt# mount -t ext2 /dev/hdb2 /mnt/2

no complaints -- IT WORKED? hmm! how about partition 5:

	root: /mnt# mount -t ext2 /dev/hdb5 /mnt/5
	mount: wrong fs type, bad option, bad superblock on /dev/hdb5,
		   or too many mounted file systems

can't mount #1 or #5? but #2 is okay?

	root: /mnt# df -h
	Filesystem            Size  Used Avail Use% Mounted on
	/dev/hda2             182M   47M  126M  27% /
	/dev/hda1             7.6M  5.3M  1.9M  73% /boot
	/dev/hda5             228M  203M   13M  94% /home
	/dev/hda6             1.8G  828M  953M  47% /usr
	/dev/hda7             1.5G  1.4G  133M  92% /var
	/dev/hdb2             232M   24M  196M  11% /mnt/2  <== this one's okay

hdb[125] are all "Linux" filesystem type 83 (ext2, right)? but
only hdb2 would mount? very much odd, here.

ideas? (i think this was my slink disk drive -- i'd like to use
it to alleviate some space pressure on my woody server...)

DEBIAN NEWBIE TIP #94 from Joost Kooij <joost@topaz.mdcc.cx>
:
How do you RESTORE THE DEFAULT PERMISSIONS back on the / tree?
If you have a clean host with very similar filesystem contents,
try this:
	ssh root@okayhost "find / -regex '/\(mnt\|proc\|tmp\)/.*' -prune -or \
	  -not -type l -not -type s -printf '%04.4m %u %g %p\n' " \
	| while read mode user group path
	do 
	  chown $user.$group $path 
	  chmod $mode $path 
	done 
Alternatively, create a huge script like this:
	find / -regex '/\(mnt\|proc\|tmp\)/.*' -prune -or \
	  -not -type l -not -type s -printf 'chown %u.%g %p\nchmod %m %p\n' \
	  > fixperms.sh
And copy that to the broken machine and run "sh fixperms".
  It might not fix all files, unless the two hosts are nearly
equal, but enough to let you find the missing ones to fix by
hand.  Maybe /home/* will need special care.
