Raw Read Error Rate Fail
I’ve shared a lot of Backblaze data about hard drive failure statistics. While our system handles a drive failing, we prefer to predict raw read error rate 1 drive failures, and use the hard drives’ built-in SMART metrics to help. The dirty industry secret? SMART stats are inconsistent from hard drive to hard drive. With nearly 40,000 hard drives and over 100,000,000 GB of data stored http://www.computerworld.com/article/2846009/the-5-smart-stats-that-actually-predict-hard-drive-failure.html for customers, we have a lot of hard-won experience. See which 5 of the SMART stats are good predictors of drive failure below. And see the data we have started to analyze from all of the SMART stats to see which other ones predict failure. S.M.A.R.T. Every disk drive includes Self-Monitoring, Analysis, and Reporting Technology (SMART https://en.wikipedia.org/wiki/S.M.A.R.T.), which reports internal information about the drive. Initially, we collected a handful of stats each day, but at the beginning https://www.backblaze.com/blog/hard-drive-smart-stats/ of 2014 we overhauled our disk drive monitoring to capture a daily snapshot of all of the SMART data for each of the 40,000 hard drives we manage. We used Smartmontools to capture the SMART data. But, before we dig into the data, we first need to define what counts as a failure. What is a Failure? Backblaze counts a drive as failed when it is removed from a Storage Pod and replaced because it has 1) totally stopped working, or 2) because it has shown evidence of failing soon. A drive is considered to have stopped working when the drive appears physically dead (e.g. won’t power up), doesn’t respond to console commands or the RAID system tells us that the drive can’t be read or written. To determine if a drive is going to fail soon we use SMART statistics as evidence to remove a drive before it fails catastrophically or impedes the operation of the Storage Pod volume. From experience, we have found the following 5 SMART metrics indicate impending disk drive failure: SMART 5 - Reallocated_Sector_Count. SMART 187 - Reported_Uncorrectable_Errors. SMART 188 - Command_Timeout. SMART 197 - Current_Pending_Sector_Count. SMART 198 - Offline_Uncorrectable. We chose these 5 stats based on our experience and input from others in the industry because they are consistent across manufacturers and they are good predictors of failure.

"Self-Monitoring, Analysis, and Reporting Technology". First developed in the 1992 by leading hard drive manufacturer, S.M.A.R.T. becomes a quasi standard to monitoring and tracking sensitive values from your drive to prevent hard drives from fail. The plan was, if a hard drive says 'I will die soon', the motherboard tell us, so we can backup and change quick the drive. Unfortunately this doesn't works very often. Attributes, Values, Thresholds and S.M.A.R.T. examples Attributes describes the measured value of hard drive controller operations. The values of an attribute are: current, worst, threshold and raw. Values are normalized to a vendor specific scale. Scales could be ranged up to 100, 200 or 253. Often higher values are better than lower values. The threshold marks the value at which the hard drive could fail. The worst value is the baddest value seen for this drive at this attribute. The raw value is a vendor coded count that give, after decoding, the normal values like current, worst and threshold. S.M.A.R.T. Interpretation First some important knowledge about threshold values. If threshold is 0 the attribute has only information character. If threshold is 253 the attribute is only for testing reason. A typical attribute set could be: Attribute name: "Read Error Rate" Current: 253 Worst: 253 Threshold: 63 Raw: 0 All right , this is a nice set. Nothing happens at this attribute. Only if this attribute reach the threshold value 63, we should have to change the hard drive. Let's look on a attribute with a warning status: Attribute name: "Read Error Rate" Current: 113 Worst: 85 Threshold: 63 Raw: 1234567 The hard drive have sector read errors in the past, but work fine for now and (perhaps) work fine in the near feature. However, I would now start to make more often backups and begin to plan a hard drive change. It is difficult to make correct interpretations in general, because different vendors normalize values in different way. We can recommend to ask in vendors forum for interpretations if you are unsure. Attribute Hit List We will give a list of important attributes. We highly recommend to look at these SMART attributes first. Read Error Rate [Stores data related to the rate of hardware read errors that occurred when reading data from a disk surface] Reallocated Sector Count [When the hard drive finds a read/write/verification error, it marks this sector as "reallocated" and transfers data to a special reserved area (spare area).] Spin Retry Count [stores a total count of the spin start attempts to reach the fully operational speed.] End t
