I've got a server with four Samsung hard drives. All drives are the same model and have been bought together. The drives are SAMSUNG HE753LJ with firmware 1AA01113.
I'm getting SMART errors but I have the feeling that smartctl does not understand the value he gets from the hard drive.
Here's the result of a SMART test:
asgard:~# smartctl -H /dev/sdb smartctl version 5.38 [i686-pc-linux-gnu] Copyright (C) 2002-8 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF READ SMART DATA SECTION === SMART overall-health self-assessment test result: FAILED! Drive failure expected in less than 24 hours. SAVE ALL DATA. Failed Attributes: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 3 Spin_Up_Time 0x0007 001 001 011 Pre-fail Always FAILING_NOW 60340
I don't trust SMART because:
- It's been over one year that all disks are about to fail within less than 24 hours. Nothing blew up yet.
- Wikipedia says that "Spin-Up Time is the average time of spindle spin up (from zero RPM to fully operational [millisecs])." That would mean that the drives need about one minute to wake up?!
I would like to follow smartctl's advice and change these disks but I just don't trust the results I read.
What do you think about this? What would you do?
Thanks for your help.
