  • No.

    The local machine boots using PXE. Clonezilla itself is transferred from a TFTP server as a squashfs and loaded into memory. When that OS boots, it mounts a network share using CIFS that contains the image to be installed. All of the local SATA disks are named sda, sdb, etc. A script determines which SATA disk is the correct one (must be non-rotational, must be a specific size and type), deletes every SCSI device (which includes ATA devices too), then mounts only the chosen disk to make sure it’s named sda.

    Clonezilla will not allow an image cloned from a device named sda to be written to a device with a different name – this is why I had to make sure that sda is always the correct SSD.











  • Sometimes for maintenance, sometimes because manual intervention was necessary. The machines where we did this were built in the 90s and have been in near constant operation. Moving parts are worn out and the tolerances are gone. Replacement parts are difficult to find and expensive to manufacture, so if something more complex than a ball bearing or axle got out of alignment, we had to pound it back into place (sometimes literally).

    I personally never bypassed the interlock, I wasn’t paid enough to take on that responsibility. I would just file a downtime notice and call the on-site mechanic when needed. I didn’t give a shit about reduced output.
