July 17, 20232 yr I shuked a 2x20TB usb hard disk that was previosuly connected to the array and working and now connected via sata as the other disks, and when starting unraid I got mount error: Unsupported partition layout. I notice if I mount in the shell by hand mount -t xfs /dev/sdt I can access to the file system I also tried using the unraid device mount -t xfs /dev/md18 /dev/sdt and works as well. sg disks shows sgdisk -v /dev/sdt Caution: Partition 1 doesn't end on a 64-sector boundary. This may result in problems with some disk encryption tools. No problems found. 65566 free sectors (32.0 MiB) available in 2 segments, the largest of which is 65536 (32.0 MiB) in size. not sure what else I can check, I could download from backup but 40TB it going to take a good time.. so if I can avoid it better. This seems like a bug in unraid as I can mount by hand the disk and works.
July 17, 20232 yr Community Expert There is definitely something wrong as the mount command you used suggests there is no partition on the drive. I would expect you would have to have used /dev/sdt1 You should post your system's diagnostics zip file so we can get a better idea of what is going on.
July 31, 20232 yr Author Hey sorry I finally formated whole disk and recovered data from backup so I can not provide you such information, Thanks!
