Subject Re: [users@httpd] Apache over NFS
Date Thu, 05 Aug 2004 21:21:24 GMT
mmmmmm.... very hard to say...
I used it apache over NFS before...
Trying to write the logs, pid and lock files to a RO volume, and a common
httpd.conf (that made pid and lock file to be overwritten), were the only
problems I've had.
And these could be fixed in 2 minutes.

sorry I'm no help here :(
