This content follows the TrueNAS CORE 13.0 releases. Use the Product and Version selectors above to view content specific to different TrueNAS software or major version.

Import Disk

  2 minute read.

Use Storage > Import Disk to integrate UFS (BSD Unix), NTFS (Windows), MSDOS (FAT), or EXT2 (Linux) formatted disks into TrueNAS. This is a one-time import, copying the data from that disk into a TrueNAS dataset. Only one disk can be imported at a time, and the disk must be installed or physically connected to the TrueNAS system.

Importing an EXT3 or EXT4 filesystem is possible in some cases, although neither is fully supported. EXT3 journaling is not supported, so those file systems must have an external fsck utility, like the one provided by E2fsprogs utilities, run on them before import. EXT4 file systems with extended attributes or inodes greater than 128 bytes are not supported. EXT4 file systems with EXT3 journaling must have an fsck run on them before import, as described above.

StorageImportDisk

Use the dropdown list to select the Disk to import.

TrueNAS attempts to detect and select the the Filesystem type. Selecting the MSDOSFS file system shows an additional MSDOSFS locale dropdown menu. Use this option to select the locale when non-ASCII characters are present on the disk.

Finally, browse to the ZFS dataset to hold the copied data and define the Destination Path.

After clicking SAVE, the chosen disk mounts and its contents copied to the specified dataset at the end of the entry in Destination Path. To monitor an in-progress import, open the Task Manager by clicking the in the top menu bar. The disk unmounts after the copy operation completes. A dialog allows viewing or downloading the disk import log.

Use the same import procedure to restart the task. Choose the same entry in Destination Path as the interrupted import for TrueNAS to scan the destination for previously imported files and resume importing any remaining files.
