enlarging partition and its filesystem
by Fred Smith 20 May '16

20 May '16

Hi all! I've got a VM at work running C6 on HyperV (no, its not my fault, that's what the company uses. I'd rather gag myself than own one of th ose things.) I ran out of disk space in the VM, so the admin enlarged the virtual disk. but now I realize I don't know how to enlarge the partition and its filesystem. I'll be googling, but in case I miss it, it'd be great if someone could point me in the right direction. thanks!

You can use globbing in the package names in both cases. It is a little more work to set up but it is a lot safer to my way of thinking, particularly where there are multiple sysadmins involved. -- *** e-Mail is NOT a SECURE channel *** Do NOT transmit sensitive data via e-Mail Do NOT open attachments nor follow links sent by e-Mail James B.

Installing 32-bit CentOS 6 on a new Lenovo System x3650 M5 server?
by Alfred von Campe 19 May '16

19 May '16

Is there any known incompatibility with the latest 32-bit (i386) CentOS 6 and the latest Lenovo x3650 M5 servers? I’ve been running i386 CentOS 6.X on 3 year old x3650 M4 servers without any issues. Our development environment has not been ported to 64-bit (x86_64) yet, so we are stuck using i386 for another few months. When I try to boot from the netinstall ISO image I just get a “Boot Failed” message. Has anyone had similar issues, and more importantly, figured out a way to workaround it? Alfred

Given a list of rpms on one system (rpm -qa > list.txt), is there a one-shot command that I can run on another system to remove all of the rpms not listed and add any that are on the list and not present on the second system? -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com

Has anybody enabled this repo? I understand that it can really mess up updates and upgrades as the dependencies are rather different.
