February 23, 200818 yr Considering some of the recent threads and the popularity of messages pertaining to drives failing. It may be wise to add smartctl to the distribution and have the http interface be able to display the full S.M.A.R.T. logs to the user. By clicking on the Serial number/model number of the drive on the front panel. you could do a smartctl -a /dev/sda (or whatever) and display it to the user. It's easy enough to create a script to do daily, weekly or monthly tests on all of the drives. However, front end access to the recent data will help users determine if a drive is going to be a problem or not. In addition, buttons could be added to trigger one of the many S.M.A.R.T. tests on demand. I might suggest just installing the SMARTD daemon itself, however I think that may tend to keep the drives spun up with it's testing. I'm not sure how it all works.

February 23, 200818 yr Re: Full SMART status of drives « Reply #2 on: May 10, 2007, 11:54:45 AM » Copy the file 'smartctl' (a program) from the download directory to the root of your Flash. Then from a telnet session, type: /boot/smartctl -a -d ata /dev/sda Look at the Devices page for the device identifer (within the parentheses) for each disk and substitute that for 'sda' on the command line. This command will print out the SMART info for the drive. We'll try to get this command into the 4.1 release. I found the above from Tom, edited, among my old notes, and Tom put a smartctl.zip on the unRAID download page. It was apparently removed some time later, but it still works fine. It appears to be version 5.36, a later version might be better. For others, it is attached below. Unzip it to the flash, and follow the instructions above. Your idea is good, useful, has been requested in the past. I'd like to see a 'Get SMART report' option also save the report with a filename consisting of the disk serial number (not the disk number) and a timestamp, and be placed in a SMART logs folder of the flash. If one was automatically generated the first time unRAID initialized a drive, then there would be a baseline for later comparison.
February 23, 200818 yr Great idea - WeeboTech. Might be nice to include the # of remapped sectors in a column on the main page. That would be a good stat to monitor, and if a user noticed that number increasing on a drive, (s)he'd know to it might be time to start shopping for another drive). Thanks for posting, RobJ. I just installed it and it works great. I was surprised at the info the drive keeps about itself. If ever a person were to buy a used drive (which I don't recommend), this would be a great report to look at . Tells how many hours the drive has been powered up, most recent 5 errors that the drive, remapped sector count, times powered on, CRC errors, and a bunch of other stats. I wondered if the drive might keep some stats to user against a warranty claim - like the highest temperature that ithas even been operated at - but I did not see anyting like that. Very interesting and highly recommended!
February 23, 200818 yr Author I noticed on my newer version of smartctl and new drives, there is history of highest and lowest temperature. 194 Temperature_Celsius 0x0002 196 196 000 Old_age Always - 28 (Lifetime Min/Max 19/32) Also, the smart report has saved me in the past when I purchased used drives. I was able to tell the seller immediately the drive was bad and even though he formatted it, the drives own diagnostics are reporting bad sectors. Note to all, Any number in Pending Sectors to be remapped is a bad sign. It means sectors that have been unreadable and cannnot be remapped for some reason. In the meantime I'm working on a script to run from cron.weekly that will grab the smart reports. Robj, you gave me the idea of saving them to the Flash drive, so that's what I'll do. Probably to flash /var/log/smartctl.sdxx.txt (as a dos file so they can be viewed with note pad). I have version 5.37 (Which is the latest from sourceforge). Attached is my first version of a quick smartcheck with logging (only for -a option) add do your crons if desired.

February 26, 200818 yr Great info! Thanks! Note to all, Any number in Pending Sectors to be remapped is a bad sign. It means sectors that have been unreadable and cannnot be remapped for some reason. I was wondering if these "pending" sectors are just sectors that have had read error, but have not been subsequently written to. (Only the write causes a sector to be remapped). Unless you are running unRAID or routinely running a hard disk maintenance program that reads and writes each sector, these would crop up over time.
February 26, 200818 yr Author I was wondering if these "pending" sectors are just sectors that have had read error, but have not been subsequently written to. (Only the write causes a sector to be remapped). Yes, exactly. If you happen to run a smartctl -t short or -t long on a drive, these will usually cause an error in the test. I did find a procedure on the net that let you calculate the file associated with the LBA# from the smart log. Thereafter you could copy the file then use dd if=/dev/zero of=badfile count=xxxx to wrte zeros to the sector. Spinrite is a cleaner approach. Badblocks in non destructive write mode also works. Although I would be sure to have a backup first.
February 28, 200818 yr This is excellent! Thanks guys. Just ran a smartctl on my drives, and one of my older 200GB drives has quite a number of errors on it. Luckily I just ordered a 1TB drive. The 200GB can come out when the 1TB goes in!
