I would use rsync; over NFS if possible otherwise over ssh: (NFS performs significantly better on read than write so preferably share from the old and mount on the new)
old# share -F nfs -o [EMAIL PROTECTED],[EMAIL PROTECTED] /my/data (or edit /etc/dfs/dfstab and shareall) new# mount -r old:/my/data /mnt new# ls -l /my/data/ ls: /my/data/: No such file or directory new# rsync -aRHDn --delete /mnt/ /my/data/ new# rsync -aRHD --delete /mnt/ /my/data/ new# umount /mnt Caution! The --delete option tells rsync to delete files it might exist under /my/data/ that aren't on /mnt/, so dryrun with -n first to check! If you get interrupted or need incremental update, simply resume/catch up by repeating: new# rsync -aRHD --delete /mnt/ /my/data/ rsync will continue where it was interrupted (discarding the last incomplete file though) and remove deleted files (the --delete option) For verbosity you may want to add -v and --progress: new# rsync -aRHDv --delete --progress /mnt/ /my/data/ If you can't share via NFS, like for security reasons: new# rsync -aRHDv --delete --progress old:/my/data/ / or old# rsync -aRHDv --delete --progress /my/data/ new:/ This is even possible via a gatekeeper: new# rsync -aRHDv --delete --progress -e 'ssh gate ssh' old:/my/data/ / old# rsync -aRHDv --delete --progress -e 'ssh gate ssh' /my/data/ new:/ Pål This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
