You may have hit a cp and or shell bug due to the directory naming topology. Rather then depend on cp -r I prefer the cpio method: find * print|cpio -pdumv dest_path I'd try the find by itself to see if it yields the correct file list before piping into cpio... -Original Message- From

Yes, the link explains quite well the issue we have. Only difference is that server1 can be manually rebooted, and while it's still down I can mount ZFS pool on server2 even without -f option, and yet server1 when booted up still mounts at same time. Just one questiong though. Is there any ETA w
