ZFSLOADER(8)						    BSD System Manager's Manual 					      ZFSLOADER(8)

zfsloader -- kernel bootstrapping final stage DESCRIPTION
zfsloader is an extended variant of loader(8) with added support for booting from ZFS. This document describes only differences from loader(8). ZFS FEATURES
zfsloader supports the following format for specifying ZFS filesystems which can be used wherever loader(8) refers to a device specification: zfs:pool/filesystem: where pool/filesystem is a ZFS filesystem name as described in zfs(8). If /etc/fstab does not have an entry for the root filesystem and vfs.root.mountfrom is not set, but currdev refers to a ZFS filesystem, then zfsloader will instruct kernel to use that filesystem as the root filesystem. ZFS COMMAND EXTENSIONS
lsdev [-v] Lists ZFS pools in addition to disks and partitions. Adding -v shows more ZFS pool details in a format that resembles zpool status output. lszfs filesystem A ZFS extended command that can be used to explore the ZFS filesystem hierarchy in a pool. Lists the immediate children of the filesystem. The filesystem hierarchy is rooted at a filesystem with the same name as the pool. FILES
/boot/zfsloader zfsloader itself. EXAMPLES
Set the default device used for loading a kernel from a ZFS filesystem: set currdev=zfs:tank/ROOT/knowngood: SEE ALSO

amzfs-sendrecv - Amanda script to create zfs sendrecv DESCRIPTION
amzfs-sendrecv is an Amanda application implementing the Application API. It should not be run by users directly. It create a zfs snapshot of the filesystem and backup the snapshot with 'zfs send'. Snapshot are kept after the backup is done, this increase the disk space use on the client but it is neccesary to be able do to incremental backup. If you want only full backup, you can disable this feature by setting the KEEP-SNAPSHOT property to 'NO'. Only the restoration of the complete backup is allowed, it is impossible to restore a single file. The application is run as the amanda user, it must have many zfs priviledge: zfs allow -ldu AMANDA_USER mount,create,rename,snapshot,destroy,send,receive 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 diskdevice in the disklist (DLE) must be one of: Desciption Example ---------- ------- Mountpoint /data ZFS pool name datapool ZFS filesystem datapool/database ZFS logical volume datapool/dbvol The filesystem doesn't need to be mounted. PROPERTIES
This section lists the properties that control amzfs-sendrecv's functionality. See amanda-applications(7) for information on the Application API, application configuration. DF-PATH Path to the 'df' binary, search in $PATH by default. KEEP-SNAPSHOT If "YES" (the default), snapshot are kept after the backup, if set to "NO" then snapshot are no kept and incremental backup will fail. 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-sendrecv application to backup a zfs filesystem. define application-tool amzfs_sendrecv { comment "amzfs-sendrecv" plugin "amzfs-sendrecv" #property "DF-PATH" "/usr/sbin/df" #property "KEEP-SNAPSHOT" "YES" #property "ZFS-PATH" "/usr/sbin/zfs" #property "PFEXEC-PATH" "/usr/sbin/pfexec" #property "PFEXEC" "NO" } define dumptype user-zfs-sendrecv { program "APPLICATAION" application "amzfs_sendrecv" } SEE ALSO
