Re: [PLUG] Why Virtualize?

[Ugarit Ebla <ugaritebla@gmail.com>]

Luckily it was only the cpu that got fried on the physical server (RHEL5).  HP replaced it and all is well now.

Independently I had a CentOS 5 VM in Parallels running on a Mac Pro.  Of course I had complete tars of the above server.  I also had a bash script for recovery, i.e to setup ntpd,apache,sshd,perl,php,accounts etc.

I logged into the VM and I ran the bash recovery script and then I rsync'd the tar.gz files to the VM and made sure that the tens of cronjobs were also active since /var/spool/cron/$user was also recovered.  Then it worked :-)

The hard part is going to be the merging of different data sets.

As a precaution I've purchased a VPS for the company from http://www.linode.com and did the same thing there so there is less chance of loosing data in the future.

So the disk on your crashed machine was fine and you simply moved the
virtual machine to a spare server with the capacity to handle another
virtual machine?  If the failure & recovery were something different,
please do post.  Thanks.

virtualization just saved my a**.

Our production server (CentOS5.2) had a hw crash and we're waiting for HP to
come out.

I had a CentOS5.2 VM in Parallels on a Mac OS X and I restored the data and
applications to the vm and within an hour a server in vm was available.

I didn't need extra hardware.
