March 22, 201412 yr Is my disk5 bad? Do I need to replace the hard drive? I can transfer files over but it has inconsistent speeds. Also, I'm running unRaid 4.5.3, what's the benefit of upgrading to the newest version? It's been a long time since I've looked at the forums, but thanks for any help.
March 23, 201412 yr Ohhhh... Do not write to the array. Disk 5 is clearly sick, and you are correct to ask. Wait for advice from someone who was around for 4.5 -- Sorry, that's not me...
March 23, 201412 yr Is my disk5 bad? Do I need to replace the hard drive? I can transfer files over but it has inconsistent speeds. As always, please obtain a copy of your syslog (see Capturing your syslog), preferably the one that covers the session with all the errors. Then obtain a SMART report for Disk 5 (see Obtain a SMART report). Zip them and attach the zip file here. We cannot say if the drive is bad or not, without seeing these reports. It's almost as likely to be an interface problem to the drive as it is to be a bad drive. Also, I'm running unRaid 4.5.3, what's the benefit of upgrading to the newest version? It's been a long time since I've looked at the forums, but thanks for any help. See the Release Notes. There are numerous bug fixes, new features, and performance improvements since your version. I strongly recommend upgrading ASAP. You will need to upgrade first to v4.7, then make sure it's working fine with no HPA's on any drives, then upgrade to the current one, v5.0.5 at this time.
March 25, 201412 yr Author I've attached the syslog below. The smart report will come later, once I get a monitor and keyboard connected to the server. There isn't a way I can do a smart report through the browser is there? Syslog.zip
March 26, 201412 yr First, thanks for fixing the DHCP lease time (30 seconds)! That was flooding the syslog, so only the latest part is available. Syslog shows a number of bad sectors in multiple almost equal size regions, so yes the drive may be failing. My guess is a head has failed. The SMART report should show numerous Pending sectors, but I suspect will also show something mechanical is seriously wrong.
March 26, 201412 yr Author I'm not exactly sure how to obtain a smart report. I tried following the wiki but it doesn't seem like I'm doing it right. So I figured out my harddrive name is sdc and I'm guessing I have one of the newer sata controllers (I built this server in 2010)? Do I type in the console: 1. smartctl -a -A /dev/sdc 2. smartctl -a -A /dev/sdc | todos >/boot/smart.txt OR do I type in the console: 1. smartctl -t short /dev/sdc 2. smartctl -a -A /dev/sdc 3. smartctl -a -A /dev/sdc | todos >/boot/smart.txt Afterwards, I will shut down my server, pull out my flash drive and upload the smart report?
March 26, 201412 yr Author I think I got it to work. But for a reference can someone tell me which steps above is the correct order? I've attached what appears to be the smart report. What seems to be wrong with the hard drive? Is it common for western digital green hard drives to fail? smart.txt
March 26, 201412 yr 100% of drives fail. Look in the SMART report for the word FAILED or FAILING. Either of those words is a good indication of the drives' condition. RMA or replace the drive.
March 26, 201412 yr Author It's been awhile since I bought a hard drive for this server. What 2tb harddrive do you guys recommend? Does this WD Desktop Mainstream 2TB look decent: http://www.microcenter.com/product/415197/Desktop_Mainstream_2TB_Intellipower_SATA_60Gb-s_35_Internal_Hard_Drive_WDBH2D0020HNC-NRSN Or should I spend a little more to get a WD red?: http://www.amazon.com/WD-Red-NAS-Hard-Drive/dp/B008JJLZ7G/ref=sr_1_2?s=electronics&ie=UTF8&qid=1395876321&sr=1-2&keywords=WD+red I remember back in the day that seagates were having quality control issues, is that the same case? Are hitachi HD good drives? Thanks for all the help.
March 26, 201412 yr From your SMART report: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 5 Reallocated_Sector_Ct 0x0033 041 041 140 Pre-fail Always FAILING_NOW 1265 196 Reallocated_Event_Count 0x0032 001 001 000 Old_age Always - 829 197 Current_Pending_Sector 0x0032 200 200 000 Old_age Always - 0 198 Offline_Uncorrectable 0x0030 200 200 000 Old_age Offline - 0 199 UDMA_CRC_Error_Count 0x0032 200 200 000 Old_age Always - 0 200 Multi_Zone_Error_Rate 0x0008 191 191 000 Old_age Offline - 1833 the above lines are of great concern. It's actually rather rare that we get to see a report with the "FAILING_NOW" state set, usually we see them with far fewer errors and rarely see them with more probably because by the time the a drive gets to this point it rapidly fails... Given that Current_Pending_Sector is zero I think your drive has successfully remapped all the bad sectors it has found (though I'm not certain that none of your data has been corrupted). But as the Reallocated_Sector_Ct is so high there might not be many spare sectors left in case further bad spots develop. Certainly WD will RMA this drive (if it is still in warranty), I've done RMAs with them on drives with far less badness. One further note of caution, the one WD drive I have had that showed a significant value for Multi_Zone_Error_Rate failed completely after another 50 hours of heavy use. Copy your data of this drive as soon as you can and then replace it. Regards, Stephen
March 26, 201412 yr I've been switching from WD Greens (I've replaced 4 so far) to WD Reds and the Seagate NAS drives. Both of these run as cool and have about the same power requirements as the Greens plus run faster. Regards, Stephen
