I discovered some bad blocks on this machine (don't ask how - it was by
accident).

Now to look up what is at those blocks
w20-575-32# /etc/icheck -b 47572 48228 /dev/rrz2a
/dev/rrz2a:
bad mode 7833
bad mode 7834
47572 arg; frag 2 of 8, inode=9758, class=logical data block 2
48228 arg; frag 2 of 8, inode=9778, class=logical data block 13
files 713 (r=210,d=20,b=22,c=113,sl=348,p=0)
used 12160 (i=30,ii=0,b=1402,f=704)
free 18415 (b=2297,f=39)
missing 0
--------------------------------------------------------------
Look up the inodes given:
w20-575-32# ncheck -i 9758 9778 /dev/rrz2a
/dev/rrz2a:
9758 /etc/swapon
9778 /etc/Xws
-----------------------------------------------------------
Reassign the badblocks
w20-575-32# rzdisk -r 47572 /dev/rrz2c
Reassigning bad block (47572) on device (/dev/rrz2c).
The data in the reassigned block is (BAD).
w20-575-32# rzdisk -r 48228 /dev/rrz2c
Reassigning bad block (48228) on device (/dev/rrz2c).
The data in the reassigned block is (BAD).
---------------------------------------------------------
Replace binaries:
w20-575-42# cp -p /srvd/etc/swapon /etc/
w20-575-32# cp -p /srvd/usr/bin/Xws /etc/Xws
cp: /etc/Xws: Text file busy
w20-575-32# rm -f /etc/Xws
w20-575-32# cp -p /srvd/usr/bin/Xws /etc/Xws
------------------------------------------------
I will now reboot to ensure everything is happy.
