   cat /etc/version

   
   
   
   WD Terminal

   $ cat /etc/version


3. Type df -i show that inodes are 100% used.
   
   

   df -i

   
   
   WD Terminal

   $ # df -i

   Filesystem	Inodes	Used	Available	Use%	Mounted on
   /dev/sda4	258048	159	257889	0%	/mnt/HD_a4
   /dev/sdb4	258048	21	258027	0%	/mnt/HD_b4
   /dev/md1	183235392	62119697	0	100%	/mnt/HD/HD_a2


4. Run this command as root to fix the inode 100% in use issue.
   
   IMPORTANT:

   This will work only on My Cloud Mirror, EX2, and EX4 My Cloud.
   This can take 45 minutes or more and will reboot once completed.
   No services will be available during this time.

   WD Terminal

   $ /usr/sbin/inode_growth.sh &
5. SSH to the My Cloud and view the inode count with the df -i command to show that it is no longer at %100.
   
   

   df -i

   
   
   WD Terminal

   $ # df -i

   Filesystem	Inodes	Used	Available	Use%	Mounted on
   /dev/sda4	258048	159	257889	0%	/mnt/HD_a4
   /dev/sdb4	258048	21	258027	0%	/mnt/HD_b4
