PetterH Posted May 28, 2020 Posted May 28, 2020 (edited) I have had problems with one of my disks in my array since i installed it... A couple of days ago i found it with "Unmountable: No file system" error. I assume it failed without doing much of any testing. I have now preformed a parity sync / data rebuild on the replacement disk but that one also has the same error. In the array operation tab i get the option to format the disk. In the guide i found on how to replace a failed disk it says nothing about having to format it after data rebuild The guide i found: https://wiki.unraid.net/Replacing_a_Data_Drive Edited May 28, 2020 by PetterH Quote
itimpi Posted May 28, 2020 Posted May 28, 2020 Do NOT format it unless you want to lose its contents. You might want to read this section of the official documentation. If a disk shows as unmountable before doing a rebuild then it will always show the same after a rebuild. The way to clear an ‘unmountable’ status is to run the appropriate file system repair tool.

PetterH Posted May 28, 2020 Author Posted May 28, 2020 So i ran it again without the -n option and it told me to run it with an -L option. Now what? This is after running it with the -L option Phase 1 - find and verify superblock... Phase 2 - using internal log - zero log...

PetterH Posted May 28, 2020 Author Posted May 28, 2020 okey so apperantly i only had to stop the array to exit maintinance mode and start it again to normal and now its good thanks @itimpi Quote
