December 6, 201015 yr Hi, I just did a parity check on my array, and it came back with 791 errors in the web GUI for the parity drive. I proceeded to obtain a SMART report for that drive and I found the following: SMART Attributes Data Structure revision number: 16 Vendor Specific SMART Attributes with Thresholds: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_ FAILED RAW_VALUE 1 Raw_Read_Error_Rate 0x002f 200 200 051 Pre-fail Always - 0 3 Spin_Up_Time 0x0027 100 253 021 Pre-fail Always - 0 4 Start_Stop_Count 0x0032 100 100 000 Old_age Always - 137 5 Reallocated_Sector_Ct 0x0033 200 200 140 Pre-fail Always - 0 7 Seek_Error_Rate 0x002e 200 200 000 Old_age Always - 0 9 Power_On_Hours 0x0032 099 099 000 Old_age Always - 1415 10 Spin_Retry_Count 0x0032 100 100 000 Old_age Always - 0 11 Calibration_Retry_Count 0x0032 100 253 000 Old_age Always - 0 12 Power_Cycle_Count 0x0032 100 100 000 Old_age Always - 1 192 Power-Off_Retract_Count 0x0032 200 200 000 Old_age Always - 0 193 Load_Cycle_Count 0x0032 200 200 000 Old_age Always - 137 194 Temperature_Celsius 0x0022 126 100 000 Old_age Always - 26 196 Reallocated_Event_Count 0x0032 200 200 000 Old_age Always - 0 197 Current_Pending_Sector 0x0032 200 200 000 Old_age Always - 12 198 Offline_Uncorrectable 0x0030 200 200 000 Old_age Offline - 22 199 UDMA_CRC_Error_Count 0x0032 200 200 000 Old_age Always - 0 200 Multi_Zone_Error_Rate 0x0008 200 200 000 Old_age Offline - 0 SMART Error Log Version: 1 No Errors Logged SMART Self-test log structure revision number 1 Num Test_Description Status Remaining LifeTime(hours) LBA _of_first_error # 1 Short offline Completed without error 00% 1414 - # 2 Short offline Aborted by host 90% 1414 - SMART Selective self-test log data structure revision number 1 SPAN MIN_LBA MAX_LBA CURRENT_TEST_STATUS 1 0 0 Not_testing 2 0 0 Not_testing 3 0 0 Not_testing 4 0 0 Not_testing 5 0 0 Not_testing Selective self-test flags (0x0): I noticed that Current_Pending_Sector is 12 and Offline_Uncorrectable is 22... however Reallocated_Sector_Ct is still 0. This is a 1 month old WD 2TB Green drive. I ran a short test and it came back with no errors. Finally I downloaded my syslog ... it is attached. Can anyone help me to interpret this data and let me know if I should be concerned? Thank you! syslog_Dec5.zip
December 6, 201015 yr Wanted to give a reply while you wait for others to chime in. It looks like you have compatability issues on the drive, at least the errors look like the ones I got when I installed mine. Did you install the jumper on pin 7 and 8? These advanced format drives must have the jumper in unRAID. If installed did you install it after you installed it into the system and ran a parity check?
December 6, 201015 yr Author I didn't even realize there were jumpers on the drive... no I didn't set any jumpers, just installed it and let unRAID do it's thing. What exactly does this jumper do? Also how would a jumper position explain the offline_uncorrectable sectors?
December 6, 201015 yr Read this thread, it is long, but should get you everything you need to fix the issue. http://lime-technology.com/forum/index.php?topic=5384.0
December 6, 201015 yr Author Thanks... I actually started searching and reading through this and other posts based on your comments. One thing I am still not clear on though - the following WIKI (http://lime-technology.com/wiki/index.php?title=Advanced_Format_Drives&redirect=no) does not state anything about preclearing the drive yet I'm reading everywhere that this is a requirement... Can you tell me if I need to preclear the drive? If so, can I do this from the web GUI or do I need to telnet to the server and run a command? Do I do this before or after I install the jumper? Thanks!
December 6, 201015 yr Author Can anyone modify the following step by step instructions from the wiki and insert the disk pre-clearing instructions at the point where I need to do this in the procedure? 1.Run a parity check. If there are errors, do NOT proceed, seek help in the forums. 2.Stop the array, power down the unRAID server. 3.Put the Advanced Format drive into compatibility mode (take the action specified on the chart above). This may involve physically removing the drive from the server, or it may not, depending on your configuration. 4.Power up the unRAID server. 5.Go to the 'Devices' page and unassign the Advanced Format drive. Then go back to the 'Main' page and Start the array. The missing disk will be running in emulated mode, and your array will not have parity protection at this point. 6.Stop the array, go back to the 'Devices' page, and assign the Advanced Format drive to the missing disk slot. 7.Go back to the 'Main' page and Start the array. A Data-Rebuild should begin. Let it finish (this will take a long time). 8.Once the Data-Rebuild is complete, run another parity check. After the parity check completes with no errors, then your parity protection is restored. If the parity check returns errors, seek help in the forums. My drive in question is my parity drive but I am assuming the instructions are the same for this drive vs a data drive? Thanks!
December 6, 201015 yr 1. Run a parity check. If there are errors, do NOT proceed, seek help in the forums. (I wouldn't bother with this as you will be wiping the disk) 2. You will need to un assign the parity drive (this will leave you un protected for the time you are pre-clearing, could take a while) 3. Stop the array 4. Power down the unRAID server. 5. Put the Advanced Format drive into compatibility mode (take the action specified on the chart above). This may involve physically removing the drive from the server, or it may not, depending on your configuration. 4. Power up the unRAID server. 5. Run the pre_clear script ( this will take a while and if you telnet in you will need to make sure your computer you are telneting in from will not sleep during the procedure. If it does the pre clearing script will stop Make sure you get the right drive as it will over write everything on a drive that you do not want to pre clear. 6. Stop the array, go back to the 'Devices' page, and assign the Advanced Format drive to the missing disk slot. 7. Go back to the 'Main' page and Start the array. A Data-Rebuild should begin. Let it finish (this will take a long time). 8. Once the Data-Rebuild is complete, run another parity check. After the parity check completes with no errors, then your parity protection is restored. If the parity check returns errors, seek help in the forums. Now when I did this I ran a pre_clear without the jumper, then jumpered the drive and did another pre_clear. I am not sure this step is needed. I also took my array off line for the time I was running the preclear script. Less chance of a disk failure. It took appx 16 hrs with two pre clears.
December 6, 201015 yr Author Thank you... and lastly, the preclear script I need to run - what is the exact command line I type, and is this script already part of unRAID or do I need to download and install this? If so, where do I get it?
