comment If one SMTP Server is down, routing all requests to another, how to achieve?
I've recently tried to implement this, and came up with the fact that load balancing SMTP isn't so simple. You either have to enforce the use of authenticated SMTP (try switching 10,000 clients' configuration to this new configuration sometime), or have a load balancer that only allows certain IP ranges to send e-mail, or you'll have an open proxy server. Unfortunately, I haven't found a load balancer that does the latter yet.

comment 100% uptime for a web application
I think it's more a matter of perception than reality. I'm willing to bet that this customer perceives that Google is up 100% of the time. Of course, Google could go down for an hour every night for maintenance at 3am, but they would never know because they're not using it at that time.

comment Proliant ML350 G3 System board failure
This is an excellent example of why RAID isn't backups. If your data exists only on these drives, then attempting to recover that data will require a tricky and easy-to-get-horribly-wrong process, that will only work on 11+ year old hardware that you hope is going to be in working condition. Recovering your data from real backups that aren't on this same hardware is trivial.

This is the best answer so far, with the most helpful information and the best details.

comment Why is scp with compression slower than without?
He was specifically asking why the transfer rate was lower, but I suspect ssh actually calculates this by dividing data size by the total time the whole operation takes, and not separating the part where it compresses data and the part where it copies the data over the network.

comment exim4 is showing a TLS error on connection… (gnutls_handshake)
This might not have helped the original poster, but it did help me. The difference I suppose, is that I'm trying to test STARTTLS on a test server, using the live server's SSL cert. And, well, that just won't work until the test server becomes the live server.

comment Why is GlusterFS so slow here?
Note: Gluster v3.7 was released on May 18, 2015. No word on whether it fixes the small file issue yet.

comment MySQL not allowing remote connections from new server
Or... not? I had before, but I used a hostname and wildcard instead of an IP address with wildcard. I'd changed that in the host table but not the user table. Fixing this inconsistency now allows me to connect. Thanks!

Oops, I already had. I'll add that to my question.

comment Syntax error when setting up master-master replication in MySQL
Cool. Um, why can't I run the command "start master" on the master 2/slave 1?

comment Syntax error when setting up master-master replication in MySQL
There are many howtos on the internet for setting up Master-Master replication. Here's one I'm following: erlycoder.com/43/…

comment Syntax error when setting up master-master replication in MySQL
Yup, start slave works! Also, the slave is working perfectly as a slave. I see "Slave_IO_Running=yes" and "Slave_SQL_Running=yes" in the status query. Now I'm trying to make the first master into a slave too, so that they can both be masters and both be slaves. The point is high availability and the ability for any of our servers to connect to either server and write to the databases.

comment Convert existing servers to a failover cluster
Also, it seems that Docker is more of an application packager? We don't do much beyond hosting some websites, e-mail, and VoIP so I'm a bit unclear how this would help.

comment Convert existing servers to a failover cluster
Did you mean Docker on Gluster? Gluster, being a distributed network filesystem, would probably work better as the underlying filesystem to Docker, which I would imagine, wouldn't even notice if Gluster is there or not. I've already got that part set up, I don't think I need to do it all over again. :)

comment Ubuntu Server hanging on adding swap
Note: The easy way of doing this with modern versions of GRUB is by editing /etc/default/grub and add "nomodeset" (separated by a space) to the end of the GRUB_CMDLINE_LINUX_DEFAULT variable.

comment What options exist for changing usernames transparently in Webmail?
Option number three is one that I had never considered before, thank you. Modifying software to suit our needs could technically be an option too, but the need for frequent security updates makes that kind of thing a huge pain in the butt. Adding users with the same mailbox is a far more graceful solution.

comment What options exist for changing usernames transparently in Webmail?
No, it's not a dupe. I saw that question before I asked this one. It's actually the reverse situation. Logging in with just the username part of the e-mail address is not a problem - if the user@ourdomain.com address exists. If it's user@hosteddomain.com, then they need to use the full e-mail address. Customers should be able to log in with either Username = user or Username = user@ourdomain.com.

comment What options exist for changing usernames transparently in Webmail?
No, this is backwards. Customers who use our domain do not include the @ourdomain.com part, they just log in with "myuser". Customers with virtual domain hosting include their full e-mail address.
