Funny you mentioned this as I almost said to use:

g.stat.det -N file < /dev/null > output.file

then look at the end of the output.file and you will have the group number where the problem is. I just didn't mention it because from the size of the file, it looked like output.file would be mega-big!!

Rod,

        Another way to possibly determine the group number where the problem
occurs is to LIST the file using the NO.PAGE option.  When LIST hits the bad
blink it will likely melt down with the same message you've been getting.
Take the last record key displayed prior to the error message and use the
RECORD verb (or the hash option of uvfixfile) to determine the group number.
The group with the bad blink will likely be the same group.  I'd recommend
using "TERM 80,32767" before the LIST to reduce pagination of the listed
record keys.

Hope this helps!

Subject: [U2] Determine bad block in universe hash file


I got the following message-

Computed blink of 0xFF6800 does not match expected blink of 0xAAA5800

Detected within group starting at address 0x14E7800

The  module of the file is 8581 so the group starting address must be in an
overflow record. I'm trying to use "uvfixfile" to trace the blocks to maybe
fix the problem, but it has to have a starting group number within the
primary group. I ascii dumped that section of the starting at 0x14E7800 and
found what looked like a key. I then used the "hash"
command under uvfixfile to determine the starting group number. I then did a
"trace", but no errors occurred.

How can I associate the overflow block to a primary block based on the
address given above?

Thanks in advance...
