Add a new option, --exclude-datasets, to replace --exclude. This makes
the naming more consistent now that there are options to filter both
snapshots and datasets.
Also add more information to the README about the distinction between
--exclude-datasets and --(in|ex)clude-snaps.
Build the zfs send and receive commands in a new subroutine, and
implement other subroutines that can be called instead of building a zfs
command and running it with system();
Add requirement for syncoid w/ remote hosts to be able to sudo without a password.
Recommends a least privilege configuration option for enabling `NOPASSWD`
Running more than one 'syncoid' at the same time to the same host resulted in two jobs referencing the same socket.
Often results in "already exists, disabling multiplexing" but has in more than one occasion failed with the following:
ControlSocket /tmp/syncoid-zfsbackup-zfsbackup@10.0.0.1-1649107066 already exists, disabling multiplexing
lzop: Inappropriate ioctl for device: <stdin>
CRITICAL ERROR: ssh -S /tmp/syncoid-zfsbackup-zfsbackup@10.0.0.1-1649107066 zfsbackup@10.0.0.1 ' zfs send -I '"'"'pool/office'"'"'@'"'"'autosnap_2022-04-04_21:00:00_frequently'"'"' '"'"'pool/office'"'"'@'"'"'autosnap_2022-04-04_21:15:00_frequently'"'"' | lzop | mbuffer -R 5m -q -s 128k -m 16M 2>/dev/null' | mbuffer -q -s 128k -m 16M 2>/dev/null | lzop -dfc | pv -s 18356312 | zfs receive -s -F 'zfs-pool/vault/office' 2>&1 failed: 256 at /usr/sbin/syncoid line 786.
Sample use-case:
Using Monit, Cron, or some other scheduler to trigger more than syncoid to the same host to sync two datasets.
Stagger the sync so that no two jobs get started at the same time, or add some form of randomization to the socket name so that two jobs may start at the same time.
Updated the install language, and commands, to better server Centos 8 and it's derivatives. Instead of using CPAN, enabling the 'PowerTools' repo will make those modules available for installation and kept current with normal OS updates.
Updated command to enable _and_ start sanoid.timer, instead of using two commands.
Add requirement for syncoid w/ remote hosts to be able to sudo without a password.
Recommends a least privilege configuration option for enabling `NOPASSWD`
Installation information for running sanoid on MacOS via launchd.
A launchd example plist file is provided in the same way equivalent
files are created on other platforms.
