Re: can't use chown with exfat!
exfat does not support user permissions.

Re: can't use chown with exfat!
Cant write within mounted point if not being the root
sudo mount -t exfat /dev/nvme0n1p8 aa
myuser@hall:~/aa$ sudo touch ss
myuser@hall:~/aa$ sudo chown myuser: ss
chown: changing ownership of 'ss': Operation not permitted
myuser@hall:~$ sudo chown myuser: aa
chown: changing ownership of 'aa': Operation not permitted

Re: can't use chown with exfat!
Permissions on exFAT, FAT or NTFS are defined at mount time with mount options.
if using the exfat-fuse driver :
if using the exfat kernel driver, I cannot find any man page, hopefully options are the same.
[Edit] : command corrected
if using the exfat-fuse driver :
Code: Select all
man mount.exfat-fuse

Re: can't use chown with exfat!
Normally only root can mount partitions. The only exception (that I know of) is if the mount point is defined (by root) in /etc/fstab, including the option "user" (or "users").
This is BTW explained in mount(8).

Re: can't use chown with exfat!
Mount permission has nothing to do with write permission.
Code: Select all
mount -t exfat -o uid=xxx,gid=xxx,umask=xxx /dev/xxx /xxx

myuser@hall:~/aa$ mount| grep aa
/dev/nvme0n1p8 on /home/myuser/aa type exfat (rw,nosuid,nodev,noexec,relatime,uid=1000,fmask=0117,dmask=0007,allow_utime=0020,iocharset=utf8,errors=remount-ro)
seem Im unable to remount it to get same result, here the default mount:
sudo mount -o remount,uid=1000,fmask=0117,dmask=0007 aa >>> Not doing anything
Code: Select all
myuser@hall:~$ mount|grep aa
/dev/nvme0n1p8 on /home/myuser/aa type exfat (rw,nosuid,nodev,noexec,relatime,fmask=0022,dmask=0022,iocharset=utf8,errors=remount-ro)
Clearly exfat is working different , with vfat or ntfs you dont have these issues..I will have to use a environment param y bashrc to remember.:
export EXFAT="uid=1000,fmask=0117,dmask=0007"
sudo mount -o $EXFAT /dev/nvme0n1p8 aa
Thanks to all

Re: can't use chown with exfat!
It depends how you mount the volume.
ntfs has a different default value for umask/fmask/dmask (0000 - cf. man ntfs-3g) but fat has the same default value as exfat (current process umask - cf. man mount). Default umask in Debian is 0022.
