% QNAP_clone_alldisk(8) Version 1.0 | QNAPHomebrew admin

NAME

QNAP_clone_alldisk — Duplicates the existing system onto ALL disks.

SYNOPSIS

| QNAP_clone_alldisk

| QNAP_clone_alldisk [-h | --help] [ -V|--version]

DESCRIPTION

Clones the CURRENT configuration onto all the disks.

It does this by calling QNAP_clone_disk -u -b n on each disk this is NOT the current location of / (root)

This feels like a rarely used command, but quite the opposite it would be appropriate to run this everytime anything on the system changed, such as installing a new package. You might run it almost everyime you logon, but heed the warnings below.

You may want to automate this process but consider where/how:

  • Via crontab(1) or crontab(5) if you do make a global system change which makes the system unusable/unbootable, then the change may get replicated to all disk before the next reboot.

  • via /etc/init.d or systemd(1) shortly after a boot. This might run after you make a change which broke networking but still allowed boot to complete, again the system may get replicated while not "working"

  • Via a .profile (bash(1) ) for a given user (root/ admin / owner?) here the system is working to some extent at least

  • At shutdown(8) again this is BEFORE a know good reboot, so most of the reservations above apply.

Options

-V, --version

: Prints the current version number and exits.

-h, --help

: Prints brief usage information.

FILES

  • /etc/fstab

: Needs to use the format LABEL=name_n_ to specify each filesystem

  • /etc/initramfs-tools/conf.d/resume

: Changes to RESUME=NONE

  • /var/log

: This is not cloned, so it represents the log of the corresponding root.
