February 25, 20215 yr Folks, I was one of the unlucky Texans impacted by the recent storms...cycling electricity (mostly off for 4 days) and then frozen busted pipes with flooding. That said, my unraid server stayed dry. I am running unRAID Server Pro v5.0.2 . I received a red ball on of my drives but when I ran smartdisk it looked okay. I ultimately just removed it from array and then reinserted it at which point a full rebuild occurred and was successful. I could access everything. The next day, I received a red ball on a different disk. Note that I had intermittent slowness in my webGUI. I ran smartdisk everything looked fine so I did the same thing. At some point in the rebuild of that disk, things went wrong. Where I sit now is that I have a started array with the "failed" disk in orange(?) status but the problem is that it says Data-ReBuild in process (with a cancel button) as well as an unformatted disk present. Nothing is moving on the Data ReBuild front from what I can see. Ohhh, I forgot to mention that I think my actual problem is one of the NIC ports is bad. I discovered a bunch of dropped packets so I just unplugged from that ethernet port on the server and everything is operating fine outside of the aforementioned issue. I think the network issue was what was creating my problem (or perhaps lack of disk problem) in the beginning. So, what should I do now? Again when I look on my other computers the failed disk is missing so it seems like something is messed up with the array. I am hoping it's a config issue and the data is still there in parity somewhere vs. just missing. Huge thank you in advance! Sincerely, Scott Albright

Unfortunately you are using a very old version of Unraid so it is going to take some work on your part to get us more information, and none of the people who usually help on the forum are running that very old version. Unraid V6 would give us a lot of info with a simple click to download a zip file to post. You should upgrade. Get us the syslog and SMART for each disk, and tell us which disks specifically are having problems, assigned slot and last 4 characters of serial. I don't know if you have unMenu installed or not and I don't even remember what other info you might be able to get from that.
February 25, 20215 yr Author Thank you. Here is the syslog. I also ran the smartctl command on each disk and they all passed. I did have one error on one of the disks even though it passed but it's not my orange/problem drive. I have included the error portion below but think it is something with the configuration vs. the disk but again I'm no expert. Thanks again! It said AT error Count: 1 ATA Error Count: 1 CR = Command Register [HEX] FR = Features Register [HEX] SC = Sector Count Register [HEX] SN = Sector Number Register [HEX] CL = Cylinder Low Register [HEX] CH = Cylinder High Register [HEX] DH = Device/Head Register [HEX] DC = Device Command Register [HEX] ER = Error register [HEX] ST = Status register [HEX] Powered_Up_Time is measured from power on, and printed as DDd+hh:mm:SS.sss where DD=days, hh=hours, mm=minutes, SS=sec, and sss=millisec. It "wraps" after 49.710 days. Error 1 occurred at disk power-on lifetime: 58461 hours (2435 days + 21 hours) When the command that caused the error occurred, the device was active or idle.

February 25, 20215 yr Power down, replace cables on disk5, power back up, start array and post new syslog.
February 25, 20215 yr Author JorgeB, Thank you for the suggestion. I will need to locate the cable and figure out exactly what to purchase/replace. Can you let me know how you arrived at that conclusion so tht I can learn? Also, when you say disk5, do you mean the disk listed in the webGUI disk 5 slot?
February 26, 20215 yr 12 hours ago, Scott A said: Can you let me know how you arrived at that conclusion so tht I can learn? Syslog is showing ATA9 errors, ATA9 is disk5, if errors persist after changing cables post a SMART report for that disk.
February 27, 20215 yr Author Ok. I'll do that next. All disks are showing up though now but I only see 4 of the 5 in Windows Explorer so it seems like the array isn't working as well. Thoughts on that?
February 27, 20215 yr Looking at that syslog you already gave us disk4 was unmountable and disabled so it will have to be repaired before or after rebuilding it.
March 3, 20215 yr Author Here is the new syslog after replacing SATA Cables. Think I replaced the correct ones. Syslog after replacing Sata Cables.txt
March 3, 20215 yr Author I still don't understand though why even if one disk is unformatted/unmounted why I can't access its contents on the array as it should be there from the parity disk. The disk is absent when looking from another PC through windows explorer. Furthermore, it is trying to rebuild the disk even though it lists it as unformatted. I let it complete one time which took hours and then nothing was there once complete. I don't want to format though yet as am concerned I lose all the data. Again, I appreciate the guidance!
March 3, 20215 yr The disk is disabled and so it is emulated by parity. Unfortunately, the emulated disk (and probably the physical disk) is also unmountable (corrupt filesystem). Parity is able to emulate the disk but it is unmountable so no files can be accessed. The filesystem must be repaired, either before or after rebuilding it. The safest approach would be to rebuild to another disk and keep the original disk untouched in case there is a problem with the rebuild. Possibly the original disk is actually mountable but the emulated disk isn't. Understanding your complete situation would be so much simpler if you were on V6, and there would be ways to work with a replacement and the original disk both. You need to get us the SMART report for at least the problem disk. It would be even better if you could get us the SMART report for all of your disks. All of that and much more would be a simple click to download a single zip on V6. Looks like they have been reworking the wiki and I don't know if there is any way to get any documentation for V5 anymore. That link I gave earlier has links to the wiki but they don't help now. What plugins do you have installed? If you have unMenu maybe you can get something from that. Basically we need the output of smartctl -a /dev/sdX where X is replaced with the sd drive letter of each of your disks.

March 3, 20215 yr Author OK. I don't have a backup so that is unfortunate. That said, I can pull the disk and put in another and see what happens. I did run SmartDisk on all drives and all passed.
March 3, 20215 yr 10 hours ago, Scott A said: I did run SmartDisk on all drives and all passed. You already said that. It isn't enough information. Do you know how to get to the command line? 11 hours ago, trurl said: What plugins do you have installed?
March 3, 20215 yr Author Thanks. No plug-ins. I do and ran smartdisk at the command line. I went ahead and removed bad disk and replaced it with a new one. Did a rebuild (of course after formatting) and the disk shows but any information that was there isn't anymore so it looks like the parity disk lost its information during the original issue. I can run smartdisk and post each one but not sure that matters now but let me know. Again, all disks are functioning and accessible. It's just that the Disk 4 information is no longer there.

The parity disk was updated when you formatted the disk so it agreed the disk was empty.

March 3, 20215 yr Did you keep the original disk as it was and rebuild to another disk? Or did you format and rebuild the original disk?
March 3, 20215 yr Author I kept the original disk and rebuilt to a new one. Here are the smartdisk runs for each drive smartsdg.txt smartsdf.txt smartsdb.txt smartsde.txt smartsdd.txt smartsdcparity.txt Edited March 3, 20215 yr by Scott A
March 3, 20215 yr If you want to try to get the data from the original disk it is going to be much simpler for us to help you and more likely to succeed if you upgrade. Study this: https://wiki.unraid.net/Upgrading_to_UnRAID_v6
March 3, 20215 yr Author Also, here is the latest clean syslog with the new disk Latest Clean Boot.txt
March 3, 20215 yr If you are comfortable with the linux command line, or even have another linux server, you could try to work with that original disk to see if it has your files, or if it can be repaired to recover some of your files. But it would require some research to figure out what to do. Or you can see about upgrading your server to Unraid V6.
March 3, 20215 yr Author I'm halfway comfortable. My next step is that I ordered a usb to SATA connector and will plug in old drive and use RSTool to see if I see anything on the old disk. If not then it's toast. If so, I'll see next steps. Only other thing would be if the parity disk still has something which seems doubtful and not sure how I would see that. It's almost like the parity for the failed disk got erased as well... I'll also look at upgrading but that looks to be a bigger task for me.
