Is there someone in the zmanda world that has the following amanda setup.
1) Solaris x86 Solaris 10
2) /usr/sfw/bin/gtar (v1.23)
3) amanda 2.6.1p2
4) amanda backup of a zfs snapshot like /path/.zfs/snapshot/path/to/dir
I am getting a seg fault when gtar tries to get the size of the zfs snapshot
directory. I believe it has to do with .zfs as a hidden directory and I am not
sure how to get around this.
Thanks
Robert
This is a truss of the gtar command that get the size of a directory.
