I'm in the process of moving files from an Ubuntu server to a Snow Leopard server. The Ubuntu server has an NFS share of around 6TB which I'd like to clone to the Snow Leopard server.
I mounted the nfs share on the Snow Leopard server and then ran
rsync -av /Volumes/FromUbuntu /Volumes/LocalCopy
After it copies around 100GB it complains that files have vanished. I'm assuming that for some reason the NFS links are going stale? What could be causing this? The Ubuntu server is not crashing and there are not connectivity issues that I am aware of. I wouldn't mind running to the rsync command over and over until the copy was finished, but it takes about 6 hours just for rsync to make it's file list.
Any suggestions? Would it be faster to just rsync over SSH? Thanks!
(PS: I've tried just using 'cp -arv' which doesn't seem to fail but according to the network traffic monitor on the Mac it seems to take twice as long to copy files as rsync after rsync has built its file list?)
UPDATE: I'm trying rsync over ssh from the mac server to the ubuntu server and it seems to been going much faster (it took less than two hours to create a file list and start transferring, where as when rsyncing from the nfs mount took around six hours just to build the initial file list.) It definitely looks like there is some problem with mounting the NFS share on the mac. Has anyone had problems with this? What about the other way around, mounting nfs shares on the mac on an ubuntu client? I was planning on hosting an NFS share for Ubuntu clients on the Mac, but now I'm getting nervous. Thanks for your input!
