this is my 3rd time rebuild VPS before this, i installed GO using GVM before. but it eats so much storage space. it around 450MB because i compile go1.4 then go1.8.1. because eat so much space and no space left on device error occurred i rebuild my vps and download go binary from golang site.

when i trying to run go file it response like this

vico@vicoartwork:~/go1.8.1/go/InfusedProject/src/infused-japanese$ go run infused-japanese.go
# command-line-arguments
/home/vico/go1.8.1/go/pkg/tool/linux_amd64/link: flushing $WORK/command-line-arguments/_obj/exe/infused-japanese: write $WORK/command-line-arguments/_obj/exe/infused-japanese: no space left on device

often if dlv, which use same command

vico@vicoartwork:~/go1.8.1/go/InfusedProject/src/infused-japanese$ dlv debug --headless --listen=:2345 --api-version=2
mkdir /tmp/go-build722616582: no space left on device
exit status 1

commit 16kb file from my local computer, push to server. and pull

vico@vicoartwork:~/go1.8.1/go/InfusedProject/src/infused-japanese$ git pull origin master

fatal: failed to write object

i already try to search bulk unnecessary files, and delete it. but still not working.

so i tried to erase my go folder and download again

vico@vicoartwork:~$ rm -rf go1.8.1
