Re: [phenixbb] moving user home directories

This is a problem (and sometimes a pain) for ccp4i, however in that case it is mitigated by two things (a) files in the project directory (ie most i/o files) don't have a path, just the file name: only files from elsewhere have the absolute path (b) as you say, they are text files, so easy to batch edit Phil On 3 Nov 2010, at 09:00, Randy Read wrote:

Hi Nat,

Although having a sysadmin change the location of your home directory is unusual, a much more common problem is buying a new computer and copying your home directory from one to the other. It can be very difficult (e.g. when going from Linux to Mac or the reverse) to get the same absolute path for your home directory. So hopefully your project migration tool will allow that too.

Regards,

Randy

Our local sysadmins moved everyone's home directory from /nfs/home/foo to /nfs/userdocs/home/foo, and it appears to have broken most people's PHENIX projects.

Uh-oh. (Doesn't this break CCP4i too? I took a look at my old grad school data and it looks like everything is using absolute paths there too - although perhaps since they're text files, it's easier to fix...)

Is there a straightforward way to fix this? Poking around in the ~/.phenix/project_db.pkl files, I can see the old paths, but I'm not exactly sure how to rewrite. My brute force attempt with sed was unsuccssful.

They're technically binary files (Python pickle format), so I doubt sed will do the job. I can write you a script to rewrite paths, but it's not a trivial problem. Migrating projects has been on the to-do list for a while and I'm close to getting it working, but I hadn't planned on anyone moving entire home directories like this. I don't suppose you can beg the sysadmins to add a symlink named /nfs/home?
