I formatted a USB drive on my mac with exfat settings and then put it into the CentOS 7 server.  When trying to mount I got the error

mount: unknown filesystem type ‘exfat’

So we need to install exfat drivers so I can mount the partition.

I tried to install exfat, but it’s not in the default CentOS repository.  I had to install nux-desktop repo.

yum -y install http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-5.el7.nux.noarch.rpm

Next, we can install the needed packages.

yum -y install fuse-exfat exfat-utils

Now  I can mount that USB drive formatted with exfat FS on my OSX laptop.

mount /dev/sdc1 /mnt/usb

We’re good to go, I can get my files now.
