Version Upgrade

10 min

Upgrade is not required at this point! Only use this guide to upgrade a validator that was installed and working using the previous guide!

This process can be completed on a validator that is running but may fall delinquent if resources are too limited. Complete using xand user without sudo privledge.

Update repo, checkout new tag, and build.

Change directory into validator repo

cd ~/solana

Update repo

git remote update origin --prune

Checkout new version number

git checkout v1.16.10

Build new release

./cargo build --release

NOTE: Try adding -j 2 to limit the build to 2 cpu cores if needed.

When build completes, create new folders for the new version.

mkdir ~/.local/share/solana/install/releases/1.16.10/bin -p

Change directory into new build release folder

cd ~/solana/target/release

Move all files to new bin folder

mv * .* ~/.local/share/solana/install/releases/1.16.10/bin

Ignore these errors...as these folders can't move:

mv: cannot move '.' to '/home/xand/.local/share/solana/install/releases/1.16.10/bin/.': Device or resource busy mv: cannot move '..' to '/home/xand/.local/share/solana/install/releases/1.16.10/bin/..': Device or resource busy

Check your current version and note so you can compare with later

solana -V

Update the symlink to point to new binaries

ln -sf <path/to/binaries/> <path/to/symlink/>

ln -sf /home/xand/.local/share/solana/install/releases/1.16.10/bin/ /home/xand/.local/share/solana/install/releases/active_release/

Check your new version is being used and compare with former

solana -V

If the new version shows up, then time to restart your validator! It will restart using the new binaries.

solana-validator --ledger ~/ledger exit --max-delinquent-stake 10 --min-idle-time 0 --monitor

NOTE: Follow along with the restart using the ./mon.sh and ./catchup.sh tools in another shell created in Monitoring your validator
