Post the exact text of the error message. I would not immediately suspect a bad drive although it is possible. Does your manager have a good reason for suspecting a bad drive? A bad drive should be diagnosed from the hardware logs. Use the script command to record your session. Then as root, use the command: "cstm". From the cstm prompt, type "runutil logtool". Do a "sl" and pay attention to the output. It will tell you what the current log was renamed to. Type "sr", and when prompted, type in the name of that log. You will get a summary of the errors. Type "fr" to format the raw log. Now type "fl" to finally view the log.

Each logtool command is two letters and you type return after the two letters. If the commands wants more info, it will ask for it. To summarize the logtool commands:

sl [switch log]
sr [select raw]
fr [format raw]
fl [formatted log]

Then "quit" to get out of logtool. And "quit" to get out of cstm.


By the way, "powerfailed" sounds like a disk driver or a lvm driver thought an operation took too long. You might have an overloaded bus or an unreasonable timeout value. This is what I would be checking first.
