October 10, 20187 yr hoping for some assistance with my unraid system after a unclean shut down. I now have a drive that unmountable and it says my parity is not valid. For some back story on exactly what happened. lost power to system and when it came back online i had to re-assign all of the drives but one came up as unmountable. at that time it started doing a parity check saying parity was not valid. I then took the array offline and unsure how to proceed. if I bring the array online I can open a few folders and see files so I know everything is not lost. Looking for some assistance recovering what I can. Unraid v 6.1.9 any assistance is greatly appreciated. thanks Keith I just created my account today so it looks like I will not be able to make any more posts after this. If someone is able to assist or ask questions I will update this original post. thanks Edited October 10, 20187 yr by KTgsxr new user
October 10, 20187 yr Please post up the Diagnostics file Tools >>> Diagnostics with your next post. Plus, tell us which disks are the ones that you think there is an issue with by Disk number or the last four digits of the serial number.
October 10, 20187 yr Author thank you for the response I have attached the requested file and last 4 of the Serial # is 3444e. tower-diagnostics-20181010-1457.zip

Please post new diags after starting the array, with or without parity assigned, as long as you're sure which drive is parity, especially since parity and disk1 are showing a RAID id, not the actual disk model/serial, if earlier you assigned the wrong disk as parity and a parity sync started it may now be unrecoverable.
October 10, 20187 yr Author that is possible I might have assigned the wrong disk. I thought it would stop me if I did not recognize it as the correct one. The server has just been up and running has not chacked for updates as was not having any issues.

No, when doing a new config (and this bug acts as a new config) all disks are considered new, Unraid has no idea which disk was which and lets you assigned them any way you want. Do another new config and assign all disks as data disks, leave parity unassigned, start the array and post new diags.
October 10, 20187 yr Author here you go. thank you again for trying to help me out tower-diagnostics-20181010-1530.zip
October 10, 20187 yr Maybe I wasn't very clear before, leave parity slot empty but assign all disks as data disks, including the one that was assigned as parity, one disk is still unassigned: Oct 10 15:29:39 Tower emhttp: 35000c5003e135973 (sde) 1953514584 Assigned it as disk7, start the array and new diags

October 10, 20187 yr Author if i'm seeing this correctly now that have that disk mounted as disk 7 I can see files on it. so i'm guessing this was not my parity drive. the drive that is not able to be mounted is my parity drive. should I repair that unmountable drive and put it back as parity and allow it to rebuild? I will wait to hear from you but this is looking promising. thank you
October 11, 20187 yr Author so it looks like I now just need to figure out how to change my disk 1 back to my Parity drive. Even tho its unmountable i can not start the array without disk 1 and cant not just move it up. How can change my array back to a 6 disk setup and then move the 7th back to Parity? I really do appreciate the help as it now looks like I have not lost any data which I was sure I was pretty sure I had.
October 11, 20187 yr Disk7 still mounts, that's good news, just do another new config, this time assign disk1 as parity, you can check parity is already valid since it mostly is but then run a correcting parity check.
October 12, 20187 yr Author Thanks I did that late last night and just got back it check and it has finished parity sync. everything appears good! My Docker tab was missing and had to disable/renable that and thats working now. I think i'm fully working with no lost files. I'm going to go ahead and update to a newer version. thank you for all your help. Keith
