January 30, 20224 yr I would like to change the array file system that is currently in place from xfs to xfs - encrypted. However, I already have data stored on the array. The interface warns me that: Quote "Changing the file system type of a device will permit you to reformat that device using the new file system. Be aware that all existing data on the device will be lost." I assume that means that I cannot change the file system on the disks without either doing one disk at a time and then rebuilding parity, or re-building the array from scratch (likely a faster option with the amount of data I have). Is there anything I can do to efficiently migrate the data from an unencrypted file system to an encrypted one?
January 30, 20224 yr Community Expert Solution You cannot change the file system type without reformatting (which effectively wipes the current data). The only way to achieve this is to first copy the data elsewhere before reformatting the drive and then (if wanted) copy it back. Parity is maintained when you reformat so will not need rebuilding.
