Problem syncing to Netapp (rsync: failed to set times on...)

2012-04-09 Thread BillDorrian
Hey folks. I have a machine that I use as an intermediary to rsync between a NAS in another building (the users there have poor bandwidth and need local storage) and the our Netapp located in our Datacenter. I get lots of the rsync: failed to set times on... errors, and files which have

I know from a lot of NAS boxes that they tend to use their internal time to stamp files instead of the time given by a copy job. The easiest way to test is to deliberately set the time off by a few hours on the box you monted the stuff on, the NAS and netapp (or the

PS: Another (ugly) workaround: Use two linux boxes, place then both on each side of the slow line. One side having the NAS mounted + running rsync server, the other having the netapp mounted. Then sync between those two linux boxes. Even if you have to use -c or --ignore-times the full read

Thanks for the suggestions, guys. I'll try testing times on the NAS device, as well as the --size-only options. These are photos - I wonder what the odds are of a modified file having the same size as the original? Bill Dorrian Network Administrator Desk: 904-273-7625 Cell: 904-859-9471
