I have two=20 other questions. Does NFS on FBSD support read-only mounts? In practice=20 I have seen some posts that claim it does not function properly or=20 mounts are found in 'rw' mode, but docs clearly read how the=20 configuration should be written. Also is NFS usable for production env? Thank you. -----Original Message----- From: Rick Macklem To: oscaruser@programmer.net Cc: freebsd-fs@freebsd.org Sent: Wed, Mar 24, 2010 5:59 pm Subject: Re: NFS Read Only Mount & NFS-failover =C2=A0 On Mon, 22 Mar 2010, oscaruser@programmer.net wrote:=C2=A0 =C2=A0 > Folks,=C2=A0 >=C2=A0 > Apparently Solaris has a mechanism for NFS failover, and is described=20 in the > below URL reference.
