Basically /var is separate and doesn't contain my gems, so I tried copying my gems in, still not found. Then I tried copying the source cache across too and that now works. Just for reference I rsync'd everything between /var/ruby/1.8/gem_home on the global and the local zones. > It would be best to root cause your issue, rather than just attempt to work > around it via another installation mechanism. Please reply if adding the > gems to each zone does not resolve the issue. This is now sorted, just sync the contents of the above directories between the host and the zone. You could install the gems into the zone directly, but that would require a writable /usr as some of the gems install binaries or scripts there. Thanks for the replies, you stimulated something in my mind so I went back to check things :) Thanks Matt ___ zones-discuss mailing list zones-discuss@opensolaris.org

Which release of opensolaris are you using? Are you sure /usr and /lib are read-only, as that is not the usual setup in the recent releases of opensolaris? Perhaps the gem command updates files in /var, which are per zone.

I could do that, I just thought it was odd that although the files are there, ruby (or gem) doesn't think they are. This indicates to me that whatever metadata ruby uses to manage the gem collection isn't being copied to the zones. So basically I'm either going to wait for someone to help track down the ruby-zones-gems problem, or I can install ruby, rubygems and my gems from source for each zone?

Re: [zones-discuss] mongrel rails in a zone
My guess is that your zones lack /var/ruby.* Did you install ruby+friends in the global zone using packages, from a tar file, or from source compilation? A package install from the global zone should install the package contents into all zones, properly handling /usr verses /var. If your means of installation insists on writing to /usr/ruby, they you could create a writeable /usr/ruby filesystem (using zonecfg add fs) so that you can install ruby into every zone. Adding a lofs filesystem, that maps to a directory in the global zone, is straightfoward. -Steve L.

[zones-discuss] mongrel rails in a zone
Hello, I've got an opensolaris box running several websites from mongrel clusters, and I'd like to have each site's cluster running in an isolated zone. I've been through the administrative guides and FAQs pertaining to zones and managed to get a zone created and running without problems. The problem I'm having is that although the zone is sharing /usr and /var, the zone cannot use any of the ruby gems that I have installed. For example I've installed mongrel, rails, capistrano and all dependencies into the global zone and they work perfectly. Unfortunately when I try to use these gems from within the non-global zone I get "gem not found errors" like so: $ mongrel_rails cluster::start /usr/ruby/1.8/lib/ruby/site_ruby/1.8/rubygems.rb:304:in `report_activate_error': Could not find RubyGem mongrel (> 0) (Gem::LoadError) [] Of course I can't re-install the gems from the zone as /usr and /var are not writable from there. Does anyone have any experience with running ruby gems from zones and might be able to give me some guidance with this? Many Thanks Matt ___ zones-discuss mailing list zones-discuss@opensolaris.org
