Michael Schmidt	57f89da69a	Fix to detect unformatted volumes in CoreOS ... The `file` command used here to check whether a device is formatted is not available for CoreOS. The effect is that the mounter tries to mount an unformatted volume which fails. This makes it quite tedious to use persistent volumes in CoreOS. This patch replaces the `file` command with `lsblk` which is available in CoreOS. I checked that it's also available on RHEL, Debian, Ubuntu and SLES.	2015-09-17 15:25:23 +02:00
Sami Wagiaalla	ab0258f259	Support formatting and mounting GCE PD without 'safe_format_and_mount' ... The GCE PD plugin uses safe_format_and_mount found on standard GCE images: https://github.com/GoogleCloudPlatform/compute-image-packages/blob/master/google-startup-scripts/usr/share/google/safe_format_and_mount On custom images where this is not available pods fail to format and mount GCE PDs. This patch uses linux utilities in a similar way to the safe_format_and_mount script to format and mount the GCE PD and AWS EBC devices. That is first attempt a mount. If mount fails try to use file to investigate the device. If 'file' fails to get any information about the device and simply returns "data" then assume the device is not formatted and format it and attempt to mount it again.
