Updating etc fstab
Do not worry, you can not brake anything by doing that.The manual commands are In this example there is 32Mi B of RAM and 512Mi B of SWAP.The mounting configuration can consist of static file systems but also swap partitions.The fstab UCI configuration file is where all the options for all devices and file systems to be mounted are defined and is located at… The fstab file is read by the command to modify that structure. The fstab file typically lists all available disk partitions and other types of file systems and data sources that are not necessarily disk-based, and indicates how they are to be initialized or otherwise integrated into the larger file system structure.

In this case transmission tries to look up for directories, can't find and create it in root fs under your mount point folder.SWAP is a SWAP-formated 512Mi B-Partition on a large USB-Harddisk.In this example, only 2Mi B of swap are being used!Be aware that there are exactly two differences between RAM and SWAP, that matter: the access time and the price.A CUPS spooling server will run just fine, when only SWAP is available, whereas some applications may perform very poorly when their data it stored on the SWAP rather then being kept in the "real" RAM.
