Check Available Free Space

Total free space required is the size of the image + 50MB (approximately 230 MB). You can use the show file systems command to verify the current disk usage.

controller# show file systems

Filesystem 1K-blocks Used Available Use% Mounted on

/dev/hdc2 428972 227844 178242 57% /none 4880 56 4824 2% /dev/shm

The first partition in the above example, /hdc2, although the actual name will vary depending on the version of FortiWLC-SD installed on the controller is the one that must have ample free space.

In the example above, the partition shows 178242KB of free space (shown bolded above), which translates to approximately 178MB. If your system does not have at least 230MB (230000KB) free, use the delete flash:<flash> command to free up space by deleting older flash files until there is enough space to perform the upgrade (on some controllers, this may require deleting the flash file for the current running version).
