+ Specify the minimum amount of free inodes on the file system

+ are free, snapshot removal kicks in just as in case of low
+ disk space.
+
+ Note that not every file system supports the concept of inodes.
+ Moreover it is not possible to reliably detect whether this is
+ the case. Therefore this feature is disabled by default. It's
+ safe to enable it for ext2/ext3/ext4 file systems on linux
+ though.

+ A value of zero (the default) deactivates this check.
