		<description>Well I'm again impressed with the level of attention the evo staff pay to their servers and customers. A bank holiday spent fixing a server must be a nightmare but they are willing to do it because they value every last customer on this and every server.

Of course you'd have to be mad not to be a bit annoyed with the server messing around again and again.

I do have an issue with accessing my email via Horde (I prefer horde you see!)

		<description>Post him down to Cornwall for a week with his family. I can make sure he walks on the beach and avoids thinking about servers. And hit him over the head with a mallet every night if necessary.

And I withdraw all the comments I've been making about Easter eggs if they added to the nightmare. I don't get allowed any till today.

		<description>Tim doesn't sleep, he has forgotten what sleeping is, we're trying to fix that, but everytime we think its sorted something like this happens, oh and he is still seeing an army of easter eggs chasing him in his sleep having spent 3 days packaging everyone's up last week!</description>

		<description>Hi Tucker :) We're starting to do the transfer in the next hour, this is what happens:

- First we do a cPanel copy of live data (200GB @ 100mbit - this is going to take ages).

- By the time the copy finishes peoples databases will be out of date... Ie, if they have forums there will be new posts etc -- so we then do an rsync on the MySQL folders, folders for your email etc etc to drag the latest data over to the new server (probably 10GB @ 100mbit so pretty quick).

- At the same time as doing the Rsync we change the IP addresses associated with the nameservers (you know you use ns27.3v0.net / ns28.3v0.net) -- these will be routed to new IPs (we've already done some DNS magic to reduce the time that these IPs are cached for your end so if we can time this right, do it over night, then most people will just switch seamlessly to the new box.

I hope that makes sense, there's a whole lot more to it but thats the gist.

It's likely that the live data copy will take upto 24 hours, maybe even longer. I can't say for sure. But I'll make sure the nameserver switch and final rsync is done around midnight (not tonight, probably tomorrow night).

I'll send out an email ASAP with full details.</description>

		<description>Thanks to Tim, Toby and the rest for getting the server sorted.

I only have one problem... my site is still crap!

Oh well at least people can now read it and mock me mercilessly :-)

Are we still on vortex? does the transfer to the new shiny still have to be performed? I just ask because I want to raise a glass to the memory of vortex, as I assume, do the majority of the posters above.

If it has been transferred - R.I.P vortex, it was a wild ride full of ups and downs, there were good times and bad times, you served us so well up until the end where you had a brain fart and passed into the great land fill in the sky.</description>

		<description>Tim.

Many thanks for getting the server and all of our sites/services back online, I hope / trust that no one has had any loss of data.

Please pass on our thanks to all involved in the recovery.

Thanks

		<description>@ Wout - Redundancy prevents against data loss and total system failures, but it does not prevent a software failure of the operating system. Having seen issues on this server several times now we are going to be swapping out the whole server over night tonight and testing the server to determine exactly what the problems have been caused by, then it will be returned to Dell for repair.


What happened today is the file system became read only, this does not have to be caused by a hardware issue, there are many many reasons for this, which range from a hardware issue to use of swap space for a prolonged period. Once the file system becomes read only you can try to remount it as read write, but this rarely works so you are generally forced to perform an FSCK, which may need to be repeated numerous times, as it was today. Each FSCK parse takes around 3-4 hours, but is different for different hardware, and the more data, the longer it takes and normally the more parses required. 

I have my website on vortex also, so have been without email all day just like everyone here.</description>
