mount: unknown filesystem type 'exfat'

Hello everyone
I've got a Centos6 machine with fuse-exfat and exfat-utils installed:
Code: Select all
rpm -qa | grep exfat
fuse-exfat-debuginfo-1.0.1-1.el7.nux.x86_64
fuse-exfat-1.2.7-1.el6.x86_64
exfat-utils-debuginfo-1.0.1-1.el7.nux.x86_64
exfat-utils-1.2.7-1.el6.x86_64
I formatted a external disk on an Apple PC using
exfat with no problems copied a file for testing and then connected the external disk to the Centos 6 machine.
fdisk shows that the device partition name is
/dev/sdb1
Code: Select all
WARNING: GPT (GUID Partition Table) detected on '/dev/sdb'! The util fdisk doesn't support GPT. Use GNU Parted.
Disk /dev/sdb: 4000.8 GB, 4000787030016 bytes

If I
, it seems to work but when I cd into /mnt/data the dir is empty.
If I umount and then try to mount the disk back again using:
Code: Select all
mount -t exfat /dev/sdb1 /mnt/data
I get :
Code: Select all
mount: unknown filesystem type 'exfat'
However I don't get this problem with a Centos7 machine. Has anyone experienced the same problem and found a solution?
Any suggestions please?
Thank you

You cannot use an el7 repo with el6.
Remove the el7 nux repo and anything installed from it. Then install the correct one.

On centos7 the directory /run/media shows all the mount points of the removable devices.
can not see a /run/media directory on centos6.
I have uninstalled
fuse-exfat-debuginfo-1.0.1-1.el7.nux.x86_64
exfat-utils-debuginfo-1.0.1-1.el7.nux.x86_64
At the moment I have:
Code: Select all
rpm -qa | grep exfat
fuse-exfat-1.2.7-1.el6.x86_64
exfat-utils-1.2.7-1.el6.x86_64
I'm not sure if it helps but parted /dev/sdb print shows:

You do appear to be using the wrong nux-dextop release package or you wouldn't have packages installed like fuse-exfat-debuginfo-1.0.1-1.el7.nux.x86_64
CentOS 6 is quite different from 7 and will not have a /run directory at all. If I remember right, automounting will use /media on el6. It's also very likely that it may not be /dev/sdb1 at all since you have a GPT label on there and as fdisk says, it doesn't support GPT so it lists only a dummy partition. You need to use gdisk or parted with a GPT labeled device.

It's empty since you have mounted the (empty) EFI System Partition on the external disk.
Use
instead.

Why does parted /dev/sd
b show /dev/sd
d?

Thank you

fdisk -l was not showing the second partition because it doesn't support GPT.
I mounted /dev/sdb2 using
and it worked.
Thank you all for your help and time.
All the best
