So, we have a server with two (or more) network interfaces are we need to be able to use more than one interface in our VDS machines. How do we set it up?
I’ve written in the past about how enterprise management vendors can act as “Gatekeepers of the Datacenter” by virtue of what technologies they do or don’t support as part of their management solutions. This rather lame dynamic is a big part of the reason why a lot of otherwise great technologies dont make it all the way into the traditional enterprise.
The problem gets further compounded when one of these “Gatekeepers” is also a platform or stack vendor. See, it’s hard to resist the temptation of delivering the absolute best management for IBM products from a Tivoli solution while shortchanging non-IBM ones. Or, to lay this on one of the aspiring members of the big 4… how about getting support for SQL Server on Oracle’s Enterprise Manager.

lvresize -L +5G /dev/VolGroup00/LogVol00
And finally since the filesystem is ext3:
e2fsck -f /dev/mapper/VolGroup00-LogVol00
resize2fs /dev/mapper/VolGroup00-LogVol00
