merve04 Posted August 27, 2019 Share #1 Posted August 27, 2019 So in the past week, I've been having issues with my main volume. The first time I noticed this my volume was degraded, disk 5 was not initialized. I did a repair and all was good. A few days later it happened again, but it wouldn't let me repair on disk 5, so I used another HDD that was in the system. On top of that problem, I also had disk 6 having system partition fail, but it also repaired it. Today I wanted to pull out disk 5, but apparently I was pulling out the wrong one, as I would reboot and volume was degraded, so I plug it back in, try another hdd, now my volume was crashed. Once again plug it back in, volume came back degraded, my old disk 5 came back online crashed as well as drive 3 is crashed which happened to be one of the drive I pulled out while trying to find disk 5. Yes I know I should probably label my drives. So the volume is now repairing itself again here for the 3rd time in less than a week. Am I just having that bad of luck??

merve04 Posted August 28, 2019 Author Share #2 Posted August 28, 2019 So repair is done, volume says normal, but hdd still reports crashed but healthy. I rebooted, same thing. What’s the deal? Quote Link to comment Share on other sites More sharing options...
flyride Posted August 28, 2019 Share #3 Posted August 28, 2019 You probably have a power or SATA cable problem with the drive that keeps failing, it appears to be physically disconnected from the system momentarily. It could be a drive problem too but I'd check cabling first. You are rolling the dice with your recovery method. Any degraded array needs to be treated very carefully. You have probably already lost some data given the crashed status. DSM tracks all disks by model and serial number. Once it decides a disk itself has crashed irrevocably, it will flag it in /var/log/disk_overview.xml. You can edit the file yourself and delete the tag for that particular disk. Reboot and DSM will regenerate it as a new drive with no flags. Quote Link to comment Share on other sites More sharing options...
merve04 Posted August 29, 2019 Author Share #4 Posted August 29, 2019 Thanks for the reply, data still seems intact to me from what I’ve tried accessing thus far. I’ve decided to pull off all the data onto other HDDs and will wipe the system and restart. Quote Link to comment Share on other sites More sharing options...
merve04 Posted August 29, 2019 Author Share #5 Posted August 29, 2019 How does one access such files as /var/log/disk_overview.xml When I use terminal i can browse to that directory, but when using something like WinSCP i dont see the directories. Is theres a way to unhide them? Quote Link to comment Share on other sites More sharing options...
merve04 Posted August 29, 2019 Author Share #6 Posted August 29, 2019 anyway figured out how to open the file now.. so I see in the disk_overview.xml file the <SN_S300GLW2 model="ST4000DM000-1F2168"> as well as <SN_S300HFMP model="ST4000DM000-1F2168"> Under DSM in Storage manager, under HDD\SSD those hardrives based on those SN are fine and the ones reporting crashed arent in that disk_overview.xml file.

flyride Posted August 30, 2019 Share #7 Posted August 30, 2019 You might have to repeat the exercise with disk_log.xml and disk_smart_test_log.xml Quote Link to comment Share on other sites More sharing options...
merve04 Posted August 30, 2019 Author Share #8 Posted August 30, 2019 The disk_smart_test_log.xml just shows each time quick or extended test was executed. disk_log.xml does show a past WD hard drive i had several times with fails but was removed back in june.

merve04 Posted August 30, 2019 Author Share #9 Posted August 30, 2019 Problems just seem to be getting worse. As I try to remove a crashed drive, say hdd3 I follow the data cable from mobo port sata 2 (as there’s 0,1) when I boot back in, hdd 1 is gone. So power off plug back in and now drive 1 says crashed, i now have 4 hdd reporting crashed. The sata port mapping seems completely out of whack, and the only thing that’s coming to my mind is dsm 6.2.2. Been backing up 24/7 since Wednesday, still got 4 and a bit TB to go.
