What kind of services needs failover? Just plain files? Have you looked at CODA? http://www.coda.cs.cmu.edu/ It might be possible to set up to coda replicated servers. But I'm not = sure how this replication works. :)=20 But it might be worth a look. I also think it's possible to store data on a SAN, connect both servers = to it and when the master fail, make the slave mount whatever it needs. = But this kind of solution costs money, and you have to place the SAN on one = of the locations (or a third), so if you have a fire or anything you will = lose it. But it would be much easier to help if we knew what kind of services = you need failover for... =D8ystein -----Original Message----- From: BSD Freak [mailto:bsd-freak@mbox.com.au] Sent: Thursday, June 13, 2002 02:36 To: FreeBSD Questions Subject: Network RAID on FreeBSD Hi all, We have a server which is highly critical. Data loss or downtime on it=20 is not an option so we have a hardware RAID 1 and also a second "hot=20 host" (in another building) which replicates data from the main one=20 every 30 minutes (via rsync). However it is this 30 minute window that=20 concerns me because that leaves us open to 30 minutes of data loss.=20 So basically what I'm asking is (without switching to Sun equipent) is=20 it possible to do some sort of network RAID where data is written to=20 both systems simultaneously? We need our system to carry on with no=20 data loss even if one of the servers should suffer a complete system=20 failure (ie be blown up or thrown out of the window)...... --------------------------------------------------------------------- Faxes delivered directly to any email address, new to mBox!
