golang zfs package helps you manage zfs filesystems/snaphots on local/remote hosts
this package wrap runcmd package; i create for zbackup:
https://github.com/theairkit/zbackup
so, fine if you find this package useful,
but much better if you will use runcmd for your cases:
https://github.com/theairkit/runcmd
all types and methods are self-explained:
http://godoc.org/github.com/theairkit/zfs
Installation:
go get github.com/theairkit/zfsFirst, create Zfs runner: this is a type, that holds runcmd.Runner, and then use him for manage zfs filsystems/snapshots:
lRunner, err := zfs.NewZfs(runcmd.NewLocalRunner())
if err != nil {
// handle error
}
list, err := lRunner.List("zroot", zfs.FS, true)
if err != nil {
// handle error
}Useful code snippet: send zfs snapshot from local to remote host:
lRunner, err := zfs.NewZfs(runcmd.NewLocalRunner())
if err != nil {
// handle error
}
rRunner, err := zfs.NewZfs(runcmd.NewRemoteKeyAuthRunner(
user,
host,
key,
))
if err != nil {
// handle error
}
cmdRecv, err := this.rRunner.RecvSnap(dst, snapPostfix)
if err != nil {
// handle error
}
cmdSend, err := this.lRunner.SendSnap(src, snapCurr, snapNew, cmdRecv)
if err != nil {
// handle error
}
if err := cmdSend.Wait(); err != nil {
// handle error
}
// In this case EOF is not error: http://golang.org/pkg/io/
// EOF is the error returned by Read when no more input is available.
// Functions should return EOF only to signal a graceful end of input.
if err := cmdRecv.StdinPipe().Close(); err != nil && err != io.EOF {
// handle error
}
if err := cmdRecv.Wait(); err != nil {
// handle error
}
