Vault - Reinitilize /update vault


we want to reinitialize the vault cluster.
for example: i have an initialized Vault cluster, i want enable or change a config field and reinitialize.

currently we understand it is not allowed, it gives error, vault is already initialized.

please advice.



What kind of config would you change?

Based on what I have read in the docs you can change most configs (if you have the rights) after Vault is initialized.

Do you mean change the master or encryption key? That can be after init too. See


for example if i have initialized vault with logging level as warning.
if i want to change the warning level as debug for a duration lets say 2 hours and revert to warning level.

Currently i understand that i will have to take backup, destroy/delete the vault, reinit with the log change and couple of times.

is there a way i can change the vault logging level while it is initialised?


Hi pashafirdous,

Log level is not connected to storage: you set it in your config file or on the command line every time you run Vault. It’s not connected to init, except insofar as you can choose the log level to run the CLI init command with.

Also, as of 1.5 (release candidate came out yesterday) you can run vault monitor to stream logs at whatever log level you like, without restarting Vault or modifying the log level of the logs that get written to disk.
