shabos Posted August 31, 2023 Share Posted August 31, 2023 Hi I wanted to replace an old drive that was possibly failing, and so I put in a new one. It was then immediately "unmountable file system". So I formatted it - then I started the data rebuild. The rebuild took 2 days and has just finished - the drive is still empty!!!! Please help. Thanks bitpartnas-syslog-20230831-1709.zip Quote Link to comment

shabos Posted August 31, 2023 Author Share Posted August 31, 2023 So why would unraid mark a brand new disk as unmountable when it has never been formatted? Quote Link to comment

It was NOT marking the new disk as unmountable - it is the emulated one. The correct handling of unmountable drives 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.

shabos Posted September 1, 2023 Author Share Posted September 1, 2023 No dude - it was marked as emulated and unmountable. I am a software engineer that has been using plex for 10 years - I'm not making this up - since the last few updates I have noticed a ton of errant behaviour - and the problem is its not reflected in the logs.

shabos Posted September 2, 2023 Author Share Posted September 2, 2023 Several problems with this: 1) When I started rebuilding the drive from parity it still said "unmountable" - not "rebuilding" or anything - I wasn't sure it was doing the right thing - so I canned it - this is poor UI 2) Once I formatted it - it still let me rebuild from parity. Why?? So then it merrily "rebuilt" for 2 days and did absolutely nothing in the end - poor design to still allow the rebuild button if it will only spin my entire array for 2 days to achieve nothing. Both of these issues are poor design and UI feedback - previously when I have installed a brand new unused drive and purposefully replaced a failed one, it would give the correct feedback (not "unmountable") - although that was on reiserfs - maybe different prompts for XFS? Frustrating to say the least. Quote Link to comment

Because the disk was still disabled, and it needs to be rebuilt to make the array healthy again, parity has no concept of data or filesystem, it's just bits. Quote Link to comment
