It worked just perfectly. Thanks a lot @itimpi, you made my day 🙂 //ChristerB

Thanks a lot, I will try the .L option on one of the drives. //ChristerB

I have had my unRAID for several years, changed HW and added disks without any issues through the years. Now I ran into issues I never experienced before and would be very grateful for help sorting things out. So my Lsi card overheated and half of my disks stopped saying there was errors. I turned the array of and shut down the server to let it cool down. After a couple of days I turned it on again and everything seemed fine. I started the array in maintenance mode to run a Check Filesystem Status in the disks. I started a check -n and got ALERT: The filesystem has valuable metadata changes in a log which is being ignored because the -n option was used. Expect spurious inconsistencies which may be resolved by first mounting the filesystem to replay the log. So should I stop the array and mount it normally and let the disks read the log and then stop the array and restart in maintenance mode? Grateful for help figuring out how I should proceed. //ChristerB tower-diagnostics-20211020-1208.zip

So, it seemed to be a heating issue (I had put the fans on low and forgot to put it back on full). Main problem solved and I will open a new topic on potential disk errors.

Thanks a lot!

Thank you @JorgeB, after I cooled down I actually understood what the log file told me. I will check the card but I haven't touched the server for weeks and it should be well seated and cooled. Any idea on a good replacement card if it is broken. (I'll read through the recommendations that already exists on this forum) //ChristerB

I Noticed that some of the shares was gone and browsed to the GUI and shares. Only cache disk shares are visible and raid shares are gone. I checked the logs and there was a lot of disk errors. My heart stopped beating and I figured I have some major problems. Do I really have issues with 6 of the disks or what might be the problem here? Could it be one of my SATA controller cards that broke down? If someone could have a look and figure out what my issues are I would be very thankful. //ChristerB tower-diagnostics-20211011-0228.zip

@johnnie.black You are truly a Hero. Just got home and my Unraid is back to normal. Received the confirmation email 45 min ago. Event: Unraid Parity sync / Data rebuild Subject: Notice [TOWER] - Parity sync / Data rebuild finished (0 errors) Description: Duration: 21 hours, 40 seconds. Average speed: 105,8 MB/s Importance: normal Thank you for your help and support in this troubled time. I am forever thankful to you.

Stupid question. If all goes well, everything on the raid will be intact? I will go for a new disk7 as you suggest johnnie.black. I just precleared a 8TB disk intended for my raid.

@johnnie.black, you are my HERO. Thanks for your fast and understandable answers. I will look in to this when I get home from work.

I didn't find a good guide to upgrade firmware (after a bit more looking I did, but still) and I don't feel confident enough to do it (I know I suck at this). So I decided to cool down the HBA and then start it again. Attached is the new diagnostics after reboot. To my limited knowledge SMART seems fine. No read errors or allocated sectors. Disk 2 is still disabled though. How would I go about to make it online again? And how should I force rebuild of disk7. Would the guide I found here work? tower-diagnostics-20190415-2130.zip

Thanks a lot. I forgot to close the side of the chassis so it probably was overheated while doing the rebuild. So the safe thing would be 1. Shutdown unraid 2. Make sure it's cooled down 3. Make sure controller and cables are well seated 3. update firmware Reboot and ask IT Gods for mercy?

I can't really say, I need to shut it down to be able to see the disks. Of course, it could be one of the ports on one of the controllers. Is it safe to shut down the server?

Hi! I have a Unraid set up consisting of 1 parity disk, 1 cache disk and 12 data disks. One of the data disks (4 TB WD Red) had read errors and I decided to remove it and add a new disk (6 TB HGST) and rebuild. Everything looked good for 10 hours but then I started to get error messages that several disk had read errors. When the rebuild was done I had 4 disks with read errors and when I got home from work one of them (8 TB WD Red) was disabled and content emulated. I have used Unraid for several years, changed hardware several times and changed disks before without problems. What do I do know? Any suggestions would be appreciated tower-diagnostics-20190415-1818.zip

Thanks! jonathanm, never thought that was the case :-) @bjp999, The drive reports it self to be 5,860,522,532 (k).

So I decided to upgrade the parity disk with a new 6 TB harddrive from Western Digital. I precleared it by doing 2 cycles (94h) and when it was done I removed the old 4TB and replaced it with the new one and started the array. I did a Parity-Check and all was good. Then I stopped the array and shut down the server to add the previous parity disk to add more disk to the array. I booted up and started the array and began a preclear on the old disk. I browsed to "myMain" to check all disks. Then I noticed on the default view that the newley added parity disk had a HPA? How can that be? I don't have an old Gigabyte motherboard, I have a pretty new Supermicro X9SRL-F motherboard. Why does it say that my parity disk is HPA? Did I do something wrong when I did the preclear? Do I have some problems now if I want to add a 6TB disk to my storage? Please help me sort this out!! I'm running unRAID 5.05 with a pro key //Christer

Thank you DaleWilliams for helping me out. Everything seems fine now. I replaced the parity disk with a 4TB WD Red and ran a Reiserfsck on Disk1 which had zero errors

Thanks DaleWilliams! Ok, I could do a clean shutdown without any problems. I checked the cables and two of them was not quite attached to the controller card (bummer). I restarted unRAID without mounting the array and now the parity disk got a blue ball and it says "New parity disk installed". Disk1 seems ok and right now I'm doing a offline smartcl on the parity drive. What would be the best thing to do? Replace parity with a new? and start array to rebuild?

Hi! I have been using unRAID for 5 months without any issues up to now. I was transfering a file to Disk1 with ftp and when it was done I didn't see anything in the directory. I did a refresh and then it showed. I noticed in the main screen that Disk1 didn't show the temperature and that the parity disk hade a red ball next to it. So I tried to access the disk in putty but I got /bin/ls: reading directory .: Input/output error So I ran a smartcl and got root@Tower:/mnt/disk1# smartctl -a -d scsi /dev/sdb smartctl 5.40 2010-10-16 r3189 [i486-slackware-linux-gnu] (local build) Copyright © 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net Short INQUIRY response, skip product id A mandatory SMART command failed: exiting. To continue, add one or more '-T permissive' options. Now I'm getting a little panic and I tried to search through the forum and can't really find what I would do. What would my next step be? Shut down the array and check cables and then try to enable the array again? Drive to the store and replace the WD disk? Create a RMA with WD and request a replacement? Run other tests if possible? I would really apprechiate som guidance on where to start. info.zip
