I have 1 backend running linux debian sarge that exports via NFS a SVN working copy to a couple of frontend (debian etch) that read the contents of the exported NFS share called /WEB-2 (under drbd ) and publish it via apache. Sometimes when i update my working copy on my backend i don't see the changes on all the frontends as follows the output on ls on the frontends. FE-01:~# ls -alio /WEB-2/sites/http/pilot/frontend/contenuto_lista_nozze.php 17237334 -rw-r----- 0 vapache 3387 2008-05-16 11:10 /WEB-2/sites/http/pilot/frontend/contenuto_lista_nozze.php FE-02:~# ls -alio /WEB-2/sites/http/pilot/frontend/contenuto_lista_nozze.php 17237564 -rw-r--r-- 1 vapache 3801 2008-05-23 11:09 /WEB-2/sites/http/pilot/frontend/contenuto_lista_nozze.php If i remount the /WEB-1 share on the frontend the changes are seen and updated correctly on all frontends but it's clear that this behaviour is not accetable when writing codes that needs to be updated directly on production. The exportfs flag options on the exported fs on the Backend are as follows rw,all_squash,anonuid=4001,anongid=555,no_subtree_check,sync. Someone could address me in any troubleshooting steps on this issue? Best Regards, Simone Carbonara
