Additional info. I got the data moved and a smaller drive removed from
the LVM setup. I decided to play with badblocks a bit and test the old
drive. I'm testing with destructive patterns since that should
effectively erase data. The old drive reported a few errors. I did
some googling and found out that SMART can interfere with badblocks.
Basically, it accesses the drive and that creates errors. I found it
odd but decided I'd restart the test and see. If it had a bad block, it
would still be bad. I redid the test and so far, it has reported no
errors. It seems what I found does happen.
So, if anyone is running badblocks, make sure to turn off SMART for that
device until the tests have completed. Otherwise you could get negative
results. This is the command I'm using.
badblocks -wsv -b 4096 /dev/sdb
If you copy and paste, make sure to edit the device. When this is all
done, I may post some further details. Oh, my frequent commands file is
growing. ;-)
