RAID losed

  • Good day all.

    I have changed the version (5 to 6) and after create RAID 5, I go to create the file system but the RAID not appear, only appear the HD system. Not sure what is wrong or I am missing. Thank you for any help.

    Sorry I forgot

  • This behaviour is by intention to prevent users from destroying their existing file system. You have to use the 'Mount' option to mount an existing file system. If you want to re-create the file system, then use the CLI to delete it or erase the whole RAID via UI.

    Note: The feature to delete a file system has been removed in OMV6 to prevent users from deleting their data by accident.
