 |
|
I have an external hard drive formatted to XFS that I intend to use as an occasionally-connected offline backup and I want the normal user on my machine to be able to mount and write to it, for convenience.
I created the directory inside /mnt, then used chown and chmod to give ownership and full permissions to the user, and ls -l shows as such: | Code: | | drwxrwxrwx 2 armand armand 6 Oct 9 21:27 extbak |
The mountpoint is listed in /etc/fstab for read-write, allow non-root to mount: | Code: | | PARTUUID=5916f543-8185-4d1a-8d6d-6e62246cc0a1 /mnt/extbak xfs noauto,rw,user 0 0 |
However, when I actually mount the drive, ownership and permissions get clobbered back to root, and it's turned read-only for everyone else: | Code: | | drwxr-xr-x 2 root root 6 Oct 9 20:42 extbak |
Am I missing something really basic here, or how do I give the regular user read-write access to the drive? |

Change the permissions once mounted as it shows owners from the external drive's root after the mount. |

Thanks, I'll give that a go  . Is there a way to make that stick so I don't have to do that every time? |

Hi .
try to change from
to
mount options
look at
| Quote: | user
Allow an ordinary user to mount the filesystem. The name of the mounting user is written to the mtab file (or to the private libmount file in /run/mount on
systems without a regular mtab) so that this same user can unmount the filesystem again. This option implies the options noexec, nosuid, and nodev (unless
overridden by subsequent options, as in the option line user,exec,dev,suid).
users
Allow any user to mount and to unmount the filesystem, even when some other ordinary user mounted it. This option implies the options noexec, nosuid, and
nodev (unless overridden by subsequent options, as in the option line users,exec,dev,suid).
|
change the permissions/owner to the root of the device filesystem (e.g.: /mnt/usb)
