Since we are at the testing stage at the moment I will try this out as soon as I find time to do it. The logging thing wouldn't bother me since we do logging remotely via syslog. What I havent't tried out so far is setting up a machine from scratch using raid and lvm though ... I built my own set of boot-disks to get the hardware supported initially, so this might also be resolveable ...

Re: lvm with raid
Hi! * Gustavo Polillo <[EMAIL PROTECTED]> [2004-06-30 17:22]: > Is it possible to make lvm with raid ?? Is there anyone here that make it? > thanks. We just recently started tests with adaptecs zcr cards (2010S) and aic-7902 controlors. Our solution is to have one disk to hold the OS and three more that form a raid5. On top of the raid5 (which looks like one HD to the OS) we use LVM. The raid then holds userdata like /home or the root of the webserver or whatever.

Although our user base is quite small (~300) it's supposed to work perfectly for ten-thousands of Users. Another cool thing - which we don't yet use - is the mail-partition feature which alows you to spread the Users mailboxes over differnt file-systems. We decided to use Cyrus because it brings IMAP and POP3 support in one 'package' and it perfectly supports TLS/SSL secured connections. Hope that is usefull.

We use mgetty here to watch the serial lines (just two ISDN modems) and it works fine for us. It includes some features like access based on phone number of caller but we have not tested that yet. Initial setup can be a bit tricky but once it runs it makes no problems at all (which is probably the reason for the setup troubles cuz you just do it once every couple of years :) ) cheers -- j.h. jogi hofmueller <[EMAIL PROTECTED]> see message header for GnuPG (PGP) Information pgpL6gnHGnX2z.pgp Description: PGP signature
