Vault v0.6.0 :Failed to lock memory: function not implemented

[Hridyesh Pant]

Hi,

I download Mac OS X 64 bit installer from https://www.vaultproject.io/downloads.html.

while running the vault server , i am getting below error

vault server -config=config.hcl

Error initializing core: Failed to lock memory: function not implemented

This usually means that the mlock syscall is not available.

Vault uses mlock to prevent memory from being swapped to

disk. This requires root privileges as well as a machine

that supports mlock. Please enable mlock on your system or

disable Vault from using it. To disable Vault from using it,

set the `disable_mlock` configuration option in your configuration

file.

seems same issue like https://github.com/hashicorp/vault/issues/59

ulimit -l

unlimited

cat config.hcl

backend "file" {

path = "/Users/user/Documents/workspace/vault_local/vault_backend"

}

listener "tcp" {

address = "127.0.0.1:8200"

tls_disable = 1

}

default_lease_ttl="1h"

max_lease_ttl="1h"

I am able to run vault 0.5.2 using same command "vault server -config=config.hcl" .

Am i missing somethings ?

You can still use disable_mlock on OS X. I think this is reasonable behavior as it indicates that the OS doesn’t support a feature that makes Vault more secure (unless “unlocked” memory on OS X isn’t a valid attack vector).

Thanks Brian. after using disable_mlock , i am able to launch vault server.

No sweat.  For the record, that’s included in the output you originally posted. :-)

yep, i also noticed this after sending the mail.

vault 0.5.2  don't give this error , and seems vault 0.6 introduce this.
