Well no worries guys we're going to be replacing the Pluto server starting tomorrow with new hardware with 15K SAS drives. More information will follow once the machine starts getting built.

You'd switch IP's which means DNS propagation. If you're not worried about DNS propagation we can move a single site to another server no problem. Although we may have a solution to the pluto issue without people changing IP's.

Right now this machine is a very troubling one we have close to 100 IP's so that means 100 users with their own IP's. We've always ever when doing migrations to new hardware re-routed the user IP's so no down time at all. The users do not even experience DNS propagation since their IP's do not change. Unfortunately it's looking like we won't be able to do this. We could move some users onto other machines on the same VLAN thus they keep their IP's. Unfortunately for users using shared IP's that will definitely not happen as we simply do not have the capacity on any of the machines to take on an entire other server basically. So it's going to be a fun few days we'll probably know what we're going to do in a few hours then post notices and the fun will start.

We're going to see what we can do about the Pluto server maybe get creative and come up with some sort of solution I'm not sure. We'd love to move entirely off sata disks on our web servers. We have others that use them to that were tricky to migrate as well. So we'll see what can be done no promises though.

The majority of web hosts are using SATA disks not SAS as they're quite expensive. We were using SATA's almost exclusively until recently and we had some machines never have drive failures. Others had drive failures some a lot others not any. Those raptor drives are actually considered enterprise drives believe it or not: http://www.wdc.com/en/products/products.asp?driveid=495 They make enterprise SATA drives in 7.2K RPM form as well as in 10K RPM form. They advertise them with high reliability numbers and all of that. As far as the backup machines well they have several TB's of data and are pretty heavily written to and very randomized (we defrag them to help deal with this). It's surprising we haven't had a drive failure they take a beating when we're doing backups. It would not surprise me when we finish replacing the drive(s) on pluto that are showing errors that we may not see anything for a year. There was one drive that failed and at the same time another started reporting bad blocks. So probably why things did not get dropped it was not until the second drive on the other side of the raid had issues that problems came up.

You cannot migrate to a different drive type live. You would need to wipe out all data to do it. We are also in a situation where this machine cannot be replaced without user IP's changing. So no option like other machines go as far as replacing it. We guarantee 99.9% uptime we're well within that even if once in a while there is an outage. This is is really the nature of hard drive. We have had quite a few drive failures on one machine none on others. Pluto was deployed on 02-20-09 we did not see a single drive failure affecting issue until 10-10-09. It's had a string of them as of late but it's just a luck of the draw type of thing. We could deploy a new machine next week with SAS drives and have 2 drives fail the next week. Even SATA systems our backup machine which is a 12 drive setup has had zero failures. Heck even your home computers I've installed hard drives then 2 weeks later it fails. It's really a luck of a draw with these things. We've just had some bad luck with some machines where drives fail but before then cause problems requiring a reboot. Others fail and we post notice and silently replace them.

And you will now notice their post is gone and they are banned

cPanel 11.25 but it shouldn't have messed up rvskin very much unless something else is wrong. Might be a good idea to make a ticket.

There is no set number of IP's we just require justification for needing extra's along with obviously paying the additional $2/month. So you should have no problem getting a few extra IP's. Keep in mind though dedicated IP's are not necessary unless the web sites are running SSL certificates.

Did you allow for DNS propagation? Or was it simply a page not found displayed by the server? It might be best though if you make a support ticket someone might be able to assist you. Tough to offer advice when don't know your actual account.

Did you make sure to setup a wildcard subdomain in cPanel? You need to do this so putting * instead of subdomain. Then you set it to a document root folder then you can actually work with mod_rewrite to send it to specific internal url's.

On Saturday February 20th we will be upgrading the Venus server to the latest version of cPanel 11.25. We anticipate this upgrade taking no longer than an hour however with us doing many machines we cannot give a concrete time when each server will be done. We do not anticipate any service interruptions during this time. cPanel may be slower than usual when the upgrading is being performed though. cPanel 11.25 brings many great new features and has reached stable and has been tested by us in a production environment on a limited number of servers. If you have any questions about this maintenance window do not hesitate to contact us. Date: 02/20/2010 Duration: 24 hours Estimated Down Time: None
