triafgg Posted August 19, 2023 Share Posted August 19, 2023 (edited) I seem to have an error with one of my disks. I can't shut down the server, shutdown or reboot do nothing. The array is showing as started, unprotected and not showing a valid configuration, any help would be appreciated to get the array running again. I have a 2TB disk to replace Disk 1. trunr1-diagnostics-20230819-1140.zip trunr1-syslog-20230819-1047.zip Edited August 20, 2023 by triafgg Quote Link to comment
JorgeB Posted August 19, 2023 Share Posted August 19, 2023 There are also errors on parity, and multiple disks dropping it's usually a power/connection problem, type reboot in the console, if it doesn't reboot after 5 minutes force a reboot and post new diags after array start.

triafgg Posted August 19, 2023 Author Share Posted August 19, 2023 Thank you. Should I just replace the disk anyway as this screenshot attached shows parity as valid. Quote Link to comment

JorgeB Posted August 19, 2023 Share Posted August 19, 2023 Since the disks dropped offline there's no SMART for disk1 and parity. Quote Link to comment
triafgg Posted August 19, 2023 Author Share Posted August 19, 2023 Thanks Jorge. I have rebooted it now, had to force it so unclean shutdown. It is showing as failed disk so I can replace it and rebuild I think. Quote Link to comment

JorgeB Posted August 19, 2023 Share Posted August 19, 2023 SMART looks good for both disks, likely a power/connection problem, check/replace cables and if the emulated disk1 is mounting and contents look correct you can rebuild on top. Quote Link to comment
triafgg Posted August 19, 2023 Author Share Posted August 19, 2023 Hi Jorge changed cables and moved to another controller but disk1 still always showing as failed so replaced with new 2TB drive and it is now rebuilding and all data available. It was simply a failed disk, not sure why cache disks(cache and appdata with dockers on) were also unavailable but it is all back now and everything working fine. Thanks for your help.

If you had wanted to rebuild to the same drive the required process is covered here in the online documentation accessible via the ‘Manual’ link at the bottom of the GUI or the DOCS link at the top of each forum page.

triafgg Posted August 19, 2023 Author Share Posted August 19, 2023 I moved it and changed cable to check if the controller slot and cable were OK as easier to replace/move to another slot. I didn't realise that Unraid would mark as failed due to a connection error so maybe rebuilding to the same drive would be OK. Not a problem though as I will now have some extra space on the array. I can keep the old Disk1 as a spare and then I will find out if it is good or bad if another one dies, not a problem as I have others if it is bad. Thanks again. Quote Link to comment
triafgg Posted August 19, 2023 Author Share Posted August 19, 2023 Hi again, the rebuild went OK and now can see all data on Disk1, however now my parity disk is showing as not present in the overview but on the disks page shows as present but not spun up with a red cross. Smart test shows no errors so I will rebuild parity to the same disk as suggested earlier for the data disk. Quote Link to comment
triafgg Posted August 20, 2023 Author Share Posted August 20, 2023 All fixed, rebuilt the parity on the original parity disk and now everything is showing as good. Thanks itimpi and JorgeB for your help. Quote Link to comment
