[CentOS] can XFS filesystem recover rm'ed files?

[CentOS] how to troubleshoot GUI issue?

Hello, I'm using a recent install of centos 7, no GUI customizations that I recall. When I log in using the GUI it accepts my password and the mouse appears on a black screen, like it is preparing the desktop, but the desktop never appears.

[CentOS] initial setup of centos linux 7 core license information license not accepted

Did all this happen because I switched monitors? Or because I did all my setup over ssh? Otherwise, this is an FYI for other newbies who get confused by this like I did. Yesterday I set up a new centos 7 install, did updates, made all the config tweaks I like to make, and rebooted at the end to

[CentOS] Centos 7 confusion about Chinese input methods

I just tried my first Centos 7 install. I want to install input methods for Chinese. In the good old days, all I had to do was yum install a blob and I was done. Does anyone have a link or some hints that will help me? I did a search, but the hits just confuse me. thanks, Dave _

[CentOS] yum causing RPC timed out?

I just installed centos 7, yum is acting strange, experiencing RPC time-outs. Sometimes when I disable the additional repos (epel and rpmforge) it seems to make things act normal. But not this time (see below). Could I have some misconfiguration? Network glitch? What hypotheses should I be conside

[CentOS] CentOS release 5.3 (Final) yum update error TypeError: unsubscriptable object

Just FYI. This machine has been offline and not updated for several months. I booted it and ran yum update. It generated an error. I googled the error, no hits. I did "yum clean all". Tried yum update again, it finished dependency resolution and reported some missing dependencies. I can deal with t
