Subject HDD benchmark/checking tool
Date Tue, 03 Feb 2009 17:53:04 GMT
Dear hadoop users,

 

Recently I have had a number of drive failures that slowed down processes a
lot until they were discovered. It is there any easy way or tool, to check
HDD performance and see if there any IO errors?

Currently I wrote a simple script that looks at /var/log/messages and greps
everything abnormal for /dev/sdaX. But if you have better solution I'd
appreciate if you share it.
