GhostBSD, Glabel an external 240GB SSD USB 3.0 drive paritions installed with ghostbsd

Glabel, gpart, geom, or How to label GPT, GPTID partitions with out a /dev/da1p3 drive name. 

First, can you read between the lines from a manual pages that INFER a similar naming/numbering scheme exists that you can try out, yet there is not ONE example to guide you.  EXAMPLE:

Some of these  label names are carried over from the 'file label' name and not the given 'glabel' name in the listings above.

I get confused about which label goes with which partition.  So here are commands to use for finding information.

gpart status

gpart show

gpart show -l

gpart list

glabel list

# use the following command to see what labels are used with which devices.

ls -l  /dev/gpt /dev/gptid  /dev/diskid /dev/label  

# URL links to more information about glabel  and gpart commands

glabel  label -v rootfs_unirex_244g   /dev/diskid/DISK-333457EBD0F2p2

So the answer is to  Glabel your GPT UUID external USB 3.0 SSD drive,   Next use that as the first or 2nd line in the /etc/fstab file to name your SWAP Partition

/dev/label/swap-unirex-224  none    swap  sw 0   0

/dev/gpt/swap-unirex-224     none    swap  sw 0   0

swapon -aL   to  turn the swap on for all swap partitions listed in the file /etc/fstab

swapinfo  -m    will tell you how much of your swap space is used in megabytes.

swapinfo -m

Device          1M-blocks     Used    Avail Capacity

/dev/gpt/swap-unirex-224      4443      578     3864    13%

swapinfo -h in Human readable sizes

swapinfo -h

Device              Size     Used    Avail Capacity

/dev/gpt/swap-unirex-224     4.3G     578M     3.8G    13%

freecolor  -t   Is another useful tool that prints on the command line in colors red,grey, and green, a fuel gauge style  examples:  freecolor -o  ; freecolor -om;  freecolor -mt

swapctl  -l   Is another method to display your swap space memory usage
