A function f1 in my script pipes the output of the function f2 to a program.

AMZFS-SNAPSHOT(8) System Administration Commands AMZFS-SNAPSHOT(8)
NAME
amzfs-snapshot - Amanda script to create zfs snapshot
DESCRIPTION
amzfs-snapshot is an Amanda script implementing the Script API. It should not be run by users directly. It create a zfs snapshot of the
filesystem where the path specified is mounted.
PRE-DLE-* create a snapshot and the POST-DLE-* destroy the snapshot, *-DLE-AMCHECK, *-DLE-ESTIMATE and *-DLE-BACKUP must be set to be
executed on the client:
execute-on pre-dle-amcheck, post-dle-amcheck, pre-dle-estimate, post-dle-estimate, pre-dle-backup, post-dle-backup
execute-where client
The PRE_DLE_* script output a DIRECTORY property telling where the directory is located in the snapshot. The application must be able to
use the DIRECTORY property, amgtar can do it.
The script is run as the amanda user, it must have the priviledge to create and destroy snapshot:
zfs allow -ldu AMANDA_USER mount,snapshot,destroy FILESYSTEM
Some system doesn't have "zfs allow", but you can give the Amanda backup user the rights to manipulate ZFS filesystems by using the
following command:
usermod -P "ZFS File System Management,ZFS Storage Management" AMANDA_USER
This will require that your run zfs under pfexec, set the PFEXEC property to YES.
The format of the DLE must be one of:
Desciption Example
---------- -------
Mountpoint /data
Arbitrary mounted dir /data/interesting_dir
ZFS pool name datapool
ZFS filesystem datapool/database
ZFS logical volume datapool/dbvol
The filesystem must be mounted.
PROPERTIES
This section lists the properties that control amzfs-snapshot's functionality. See amanda-scripts(7) for information on the Script API,
script configuration.
DF-PATH
Path to the 'df' binary, search in $PATH by default.
ZFS-PATH
Path to the 'zfs' binary, search in $PATH by default.
PFEXEC-PATH
Path to the 'pfexec' binary, search in $PATH by default.
PFEXEC
If "NO" (the default), pfexec is not used, if set to "YES" then pfexec is used.
EXAMPLE
In this example, a dumptype is defined to use amzfs-snapshot script to create a snapshot and use amgtar to backup the snapshot.
define script-tool amzfs_snapshot {
comment "backup of zfs snapshot"
plugin "amzfs-snapshot"
execute-on pre-dle-amcheck, post-dle-amcheck, pre-dle-estimate, post-dle-estimate, pre-dle-backup, post-dle-backup
execute-where client
#property "DF-PATH" "/usr/sbin/df"
#property "ZFS-PATH" "/usr/sbin/zfs"
#property "PFEXEC-PATH" "/usr/sbin/pfexec"
#property "PFEXEC" "NO"
}
define dumptype user-zfs-amgtar {
dt_amgtar
script "amzfs_snapshot"
}
