fix(cluster_aws): moved var-lib-scylla.mount away after restart #2839
Conversation
Since scylla_create_devices fails if var-lib-scylla.mount already exists during its execution, I moved var-lib-scylla.mount from its regular location

var-lib-scylla.mount file is created by scylla_setup.
what's the error if var-lib-scylla.mount exists?
If the var-lib-scylla.mount is moved, will the RAID be mounted correctly after reboot?

We don’t know, isn’t it created by create_devices?
We saw that create devices is failing when this file exist

seem like @syuu1228 did this change few months ago:
scylladb/scylladb@c0b2933
I think we should remove it file inside create_devices script, if that's the case

In restart() we call scylla_create_devices script to setup RAID, the existing var-lib-scylla.mount won't effect it.
it only effects scylla_setup script, but we didn't call it in restart().

@ShlomiBalalis Need to check the source of the error someone touched, is it from scylla_setup, why it's called.
Currently we only directly call scylla_setup script for GCE backend in init stage.
A flag file /etc/scylla/machine_image_configured
will be created after scylla_setup -> scylla_image_setup
succeeds, then scylla-image-setup won't be called again.
There are two errors in executing scylla_setup or scylla_raid_setup:
I guess @ShlomiBalalis touched Error 2, I'm ok with this PR. |

It's fine to directly remove it without checking if it exists or not.
sudo rm -f /etc/systemd/system/var-lib-scylla.mount

@roy wanted me to save the file for debugging purposes
@ShlomiBalalis I'm merging this, but please open a bug, so we'll fix it in the correct place |
@fruch Why do we need a bug for it in scylla-machine-image? |
We need to handle this inside |
