fusermount: option blkdev is privileged
So I tried as root, and it mounted OK:
mount | grep sdc1
/dev/sdc1 on /sdc1 type fuseblk (rw,nosuid,nodev,noexec,relatime,user_id=508,group_id=508,allow_other,blksize=4096)
then as root I tried to copy a file to /sdc1:
# cp rpms.list /sdc1/
cp: cannot create regular file ‘/sdc1/rpms.list’: No such file or directory
So, what else need I do so that regular users can mount and write to usb sticks that are formatted as exfat FS?
These are the relevant rpms installed:
fuse-exfat-1.0.1-1.fc20.x86_64
exfat-utils-1.0.1-1.fc20.x86_64
Tried to recreate your issue. I didn't have a exfat formatted USB so I used mkfs.exfat to create. Then I labeled it....
I didn't do things "exactly" as you did but....
[root@f22k ~]# exfatlabel /dev/sdb1 myexfat
[root@f22k ~]# exfatlabel /dev/sdb1

In your reply, you are using root to mount. Since this is a fuse FS, why
not allow the user to mount??
/mnt is root owned , mode 755
/mnt/32GBflash is jd owned and is mode 700
