Here are some limitations and interactions of XigmaNAS:

Local User/Password feature is covered in this document. Additional notes are available in the changelog on the XigmaNAS website.

  • The local format of your storage drives will not affect how the shares work with MS Windows across the LAN.
  • ZFS and UFS are the native XigmaNAS filesystem: using another filesystem for data storage is not recommended.
  • ZFS is recommended over UFS for almost every system. UFS does not include any of the more powerful features that ZFS includes, especially checksums, which will detect bitrot and correct it if the ZFS pool includes redundancy. UFS is generally discouraged.
  • FAT, NTFS, and EXT2/3 can be used to transfer bulk data to a UFS formatted drive ONLY.
  • In XigmaNAS versions below 9.0, only EXT2/3 revision 0 with Inode size of 128 bytes supported. Revision 1 uses an inode size of 256 bytes which is not supported by FreeBSD below version 8.2. When creating ext2/3 partitions, using 128 bytes via '-I 128' could solve this problem but the file system is permanently in 'not clean' state.
  • SCSI, PATA (IDE), SATA, CF and USB drives are supported.
  • XigmaNAS's boot drive partition cannot be used as part of any RAID array. Only whole disks can be used to form a RAID array.
  • USB drives can be hot-plugged, but new external USB drives will need to be ADDED and MOUNTED, before using as described later in this guide.
  • Any drive (USB, ZIP, CD-Rom) MUST be first unmounted before removing it. A reboot could occur otherwise.
Major FreeBSD (underlying OS of XigmaNAS) old bug:

Using CIFS/SMB to read/write any file(s) on a FAT32 drive partition is known to corrupt files!
