Hi Jim, you're working varnish is 2.0.5? 2.1.5?
if varnish is 2.0.X. refer to this url.(sorry Japanese. but I put an English comment) http://wiki.xcir.net/index.php?title=Versuin2.0.x%E2%86%922.1.x%E3%81%B8%E3%81%AEVUP -- Syohei Tanaka(@xcir) http://xcir.net/ (:3[__]) 2012年2月18日2:37 Jim Hayter <[email protected]>: > I am working on upgrading from Varnish 2.0.5 running on Ubuntu 9.10 to > Varnish 3.0.0 running on Ubuntu 11.10. > > I have a few questions based on my reading of > https://www.varnish-cache.org/trac/browser/doc/changes.rst > > 1) Changes from 2.1.5 to 3.0 beta 1 states: > > - The -l (shared memory log file) argument has been changed, please > see the varnishd manual for the new syntax. > 'man varnishd' for 2.0.5 states: > > -l shmlogsize > Specify size of shmlog file.
