Hi,
I managed to backup and restore a ZFS dataset from an Illumos OS (Nexenta). It
tells me the restore failed but I compared the restored files with the existing
ones using md5sum and it matches. :) The only thing that doesn't work yet is
recursive backups of ZFS datasets.
e.g. backing up:
/volumes/nexenta03-test/ProjectsGI (ZFS dataset)
would only backup that directory no sub ZFS datasets.
I found some docs referring to ZFS_MODE = recursive. I tried setting that via
here:
Fileset {
Name = "NDMP Fileset"
Include {
Options {
meta = "RECURSIVE=yes"
meta = "USER=root"
meta = "ZFS_MODE=recursive"
meta = "TYPE=zfs"
}
#File = /var/cores
File = /volumes/nexenta03-test/ProjectsGI
#File = /volumes/nexenta03-test/ProjectsGI/GTEST
}
}
I can also see the available modes using stat client:
>C NDMP0_NOTIFY_CONNECTED 1
reason=NDMP0_CONNECTED protocol_version=4 text_reason=''

But it won't do a recusive backup. Recursive only works if the subfolder is
really a subfolder and not another ZFS dataset.
Any Ideas?
Cheers,
Oliver
