Is it bad to have /home/ on an NTFS partition? [duplicate]

  • 772

On my new computer, I didn't want to have /home on the system SSD but rather on the secondary drive which is a conventional hard drive.

I followed these instructions for moving /home to the other disk: A: Move home folder to second drive (actually these specific steps) But now I realize that the disk is NTFS format.

  • Will running home from NTFS be a problem, or perhaps a performance killer?
  • Can I convert the HDD from NTFS to ext3 (or ext4?!) without losing all the files, and how?
ntfs

    Will running home from NTFS be a problem, or perhaps a performance killer?

    • Yes, NTFS does not understand Linux permissions. If you're using Gnome, then you won't even be able to log in due to permission issues.

    • dot files on NTFS are not considered hidden files and due to the lack of permissions -anyone- can change those files without having to worry about passwords.

    • Also read this: http://en.wikipedia.org/wiki/NTFS#Linux

    Due to the complexity of internal NTFS structures, both the built-in 2.6.14 kernel driver and the FUSE drivers disallow changes to the volume that are considered unsafe, to avoid corruption.

    If you want to do it like this you are better of with FAT. But WHY break the security of a Linux system? Why?

    A better way is to put /home on ext3 or ext4 and mount the directories from the Windows partition (in that case you can use NTFS though I still advice against it). This will not break the security model but you can still share all your personal files.

    Can I convert the HDD from NTFS to ext3 (or ext4?!) without losing all the files, and how?

    GParted can do this. But it is probably quicker to move all the files elsewhere and then format the disc and copy the files back.

  2. You can't without some major tinkering with ntfs-3g, since proper unix ownership and permissions are not supported on NTFS by default.

  3. Well you can have some problems with ntfs as it does not mount automatically on ubuntu. You need to add an entry to /etc/fstab manually.

    Then when I come to think of it.. you could try to use it as home, but on the other hand ntfs is rather poor choice when you have alternatives like xfs or ext4, which will be faster and more stable on linux.

    And I think you won't be able to change the filesystem without backing up all your data on other drive.
