Built2Succeed Posted November 11, 2022 Share Posted November 11, 2022 this disk was working. Had a power outage. now the disk doesn't mount. Things I've tried: 1. Upgraded to 6.11.3 2. Ran extended disk check with no errors 3. Read file system check/repair process documentation: this part i got stuck on as I'm unable to determine file system type (it says 'auto' under file system) Not sure how to proceed with Step 3 as the documentation is unclear tower-diagnostics-20221111-1319.zip Quote Link to comment

JorgeB Posted November 11, 2022 Share Posted November 11, 2022 That disk doesn't the required Unraid partition layout, it will never mount in the array, you can see if it mounts with the UD plugin. Quote Link to comment

Not with that partition layout, some disks have been known to damage the partition after a power cut, don't ask me why but I've seen it before, Unraid uses the 1st partition only, and it requires the disk to only have one partition and that it uses the full disk capacity, your disk has multiple partitions and the 1st partition is 512MB, hence the "invalid partition layout problem", like mentioned see if the UD plugin can mount the disk, it doesn't care about the layout, as long as they are valid partitions, which by the looks of the fdisk output they might not be.

Unable to mount with UD plugin. Should I try Ubuntu Live and a disk repair utility? The exended smart check says no errors. I'm unsure how to proceed. Quote Link to comment
Vylo Posted November 12, 2022 Share Posted November 12, 2022 I'm getting this same error, I pre cleared the disks several times, when using UD to format, it says is successfully formatted but it doesn't show what FS it is to the right. I can format it to any other fs except for xfs or btrfs and I have 8 drives Quote Link to comment

JorgeB Posted November 13, 2022 Share Posted November 13, 2022 I would try testdisk first to see if it can recover the old partition, other option would be to create a new partition with the correct layout and hope the filesystem is still valid. Quote Link to comment
