Galactus Posted August 9, 2019 Share Posted August 9, 2019 Hello. I was trying to increase the storage space of my Server. I had 4 2 TB data drives. To do so, I first installed a new 4 TB parity drive, replacing the 2 TB parity drive I had. The process ran and rebuilt the new parity drive successfully. After that, I followed the same sequence when installing the replacement data drive, that is, to turn off the array, pull one of the 2 TB data drives I had and insert a new 4 TB data drive. I assigned it to the same slot as the replaced 2 TB drive and started the rebuild process which ran for several hours. After it was completed I got an error 'Unmountable: No file system', with a flag to format the new drive. I did execute the format (looking back now i think this was a mistake). After the format completed I have a now empty new drive added to the array, with all of the data that was on the removed drive missing. How can I restore the data to the array? I have the old drive I removed. Should I have formatted the drive first? I did not need to do that when replacing the parity drive? Thanks... BTW Im on version 6.7.2 Quote Link to comment

Mount the old drive with the UD plugin and copy to the array. 53 minutes ago, Galactus said: I did execute the format (looking back now i think this was a mistake). Quote Link to comment
Galactus Posted August 10, 2019 Author Share Posted August 10, 2019 Was able to correct the problem by doing as suggested. I was able to mount the old data drive, and copy to the new drive with Krusader. I did temporarily unassign the parity drive during the copy. Everything is restored and the parity sync is running. Thanks! Quote Link to comment
