you just need to do a (case sensitive)
touch ./ext3flash
this prevent swap on flash and set partition with noatime flag to save flash write
But sure you must create a swap partition on external drive (1go) and activate it by
mkswap /dev/sdb2 (where 2 is partition number)
after, create a script in /unslung (rc.1 for example) containing
# rc.1 (activ swap if present on external drive)
#!/bin/sh
/sbin/swapon /dev/sdb2
return 1
install procps top command by
ipkg install procps
to see swap size and use you can use (as said by fizze)
top
cat /proc/swaps
cat /proc/meminfo
free
hope that’s help you
