I figured out how to fix that so now /home on t2 is fixed. Regarding /usr/local, I know nothing about how that was setup, and the version from before is totally gone. However, I note that /rootpool2/local on t2 has a bunch of recent stuff, and maybe basically has a backup of /usr/local/. Perhaps somebody such as kirkby -- who setup the old /usr/local -- could comment and/or restore this. I have also mounted /disk/scratch and /disk/lmfdb on t2. I'm generally curious to hear about whether or not /home works OK for people. I was testing it yesterday with the (default) async NFS export option, and though "tar" was very fast, sometimes building Sage would fail with "file not found" issues. So I changed the NFS export option to sync, and now things seem to work fine, but are maybe slower. -- William > > John > > > On Oct 1, 12:19 pm, William Stein <wst...@gmail.com> wrote: >> Hi, >> >> I've done the final switch as outlined below.
