I greatly appreciate your offer, Keith, but it wouldn't be practical in this situation.
I need to keep the old machine running 24 x 7 (it's also a Samba file server) until the new one is fully operational. The new machine's data array is already a SCSI-attached 3U cage full of SATA-II drives (so I don't really need to borrow another cage.) The new machine only uses the motherboard-controlled hard drive for booting and a swap-file, and it only uses the 12 TB drive array (9 TB after its internal RAID-6 controller boosts reliability and performance at the expense of space) for data storage. When I started the migration project, I decided that I couldn't afford to bring the old server down long enough to connect & disconnect the SCSI array twice, so I took a couple of spare Gbit NICs and a cross-over cable to connect the hosts. Now I can move my data over a private "network" while the old server continues to serve the LAN's requests. While the data moves in the background, I am also working on configuring the NFS and Samba shares I'll want on the new server. Nobody has complained about the diminished performance of the old server... yet. If they do complain, I'll re-nice the rsync to a lower priority or something. It just chafes me a little that I'm wasting CPU cycles on both sides with encryption when I absolutely trust the security of my link. I suppose I could have asked my rsync question on a more directly rsync-related site, but I didn't want to have to explain Dirvish to those folks. -dP -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Keith Lofstrom Sent: Wednesday, March 05, 2008 2:09 PM To: Dirvish user and developer mailing list Subject: Re: [Dirvish] Is this a dumb idea? rsync without ssh On Wed 05 Mar 2008, Petcher, Daniel wrote: > I'm working on moving my dirvish server onto some new equipment and > re-organizing the archive, so I've got a few TB of data to move.

I think Daniel is using raw rsync, without dirvish, for moving between machines. That is sensible, given that he is copying raw data. However, may I suggest putting a swap cage in the old machine (if there is a slot available, a big if) or putting an E-SATA card in the old machine along with a trustworthy SATA to PATA adapter if necessary? A direct drive-to-drive copy will be faster than the network, encrypted or not. Daniel, Audio Precision is not far from me; I probably have some unused swap cages if you want to borrow them for a while.
