Yeah, that make sense to me, I do select format emulated disk option under start array option....... Too be hornesty, that option is quite confusion and attempted for new user to click...... and the whole recoery process isn't quite clear at all. But i learnt my lesson in hard way. lucky not data was lost. Thank you so much for support!

Here is the sequence: 1. replace uncountable drive with new drive 2.format new drive 3. add the new new drive to array disk 5 as replacement 4 start array and run parity rebuild 5. no data available after 14hr rebuild Lucky I run xfs_repair -L and mount the drive again. my biggest concern is No data shows on my disk after parity check/rebuild. Any thing related to my format activity? Did I get something wrong in my process recovery?

I managed to connected the failed/unmountedable disk is Unassigned disk, run the xfs_repair -L and successful mounted. I am copying the file from that to unsigned disk to Disk 4 now. Fingercross. But is my parity rebuid failed becasue i only have 1 Parity disk? shall i get another Parity disk for this case?

I replaced the failed Disk 5 with a new Hard drive actually, then i format new hard drive to create the arry. so i still have : 1. failed disk 5 2. new hard drive formate and run the rebuild. Please kindly let me know what to do now. thanks

Oh No...... is that mean. all data is gone......

Hi, one of the drive was failded and unmountedable. i did xfs_repair -n, it still shows same status. then i start rebuild with a new drive. However after 14hrs re-build/parity-check DIsk5 . there are 11.801.419 Writes to the Disk, but there is no data available any where. Could you plesae kindly help with that. it is realy frastrucated for me. tower-diagnostics-20231222-1436_disk5 failed.zip tower-diagnostics-20231223-2201_after_rebuild.zip
