Linux LVM: Reduce Filesystem and Logical Volume

March 14, 2012 – 5:07 pm | No Comment

The following example shows how to reduce the size of a filesystem mounted on an LVM logical volume. The instructions below are only for non-root filesystems. No reboot is required, but the filesystem will need to be unmounted. So, if there are any user applications using this filesystem, they will need to be stopped and the users will need to log out.

NFS “Not Owner” Error

Submitted by Igor on August 30, 2010 – 11:34 pmOne Comment

The “not owner” error is displayed on the client system (usually Solaris) when attempting to mount an NFS share from a server. This error may appear even though the share is correctly exported and the client system has full access. If you are getting a “permission denied” error, then this article is not for you and you should check here instead.

The “not owner” error is likely when the server is running NFS v. 4 and the client is running NFS v. 3 or an earlier release of v. 4. This error sometimes also appears when the NFS server is a Linux system and the client system is running Solaris.

To resolve the problem:

edit /etc/default/nfs (this location is for Solaris; for other operating environments just do a search for a file called “nfs” in /etc) on the client system
modify or add the following line: NFS_CLIENT_VERSMAX=3
save the file and attempt to mount the share again. You do not need to restart NFS. You may need to restart automounter, if that is what you are using.

The above change will force the client to use NFS v. 3, which at the moment is more widely-compatible than version four. This should not cause any problems for the NFS server or other clients.

OpenSUSE 11.4 Installation Overview

After enjoying taking apart Microsoft’s “cloud” Office 365 for the numerous shortcomings of its installation process, having to do the same for my favorite Linux distro – openSUSE – is rather upsetting. OpenSUSE installation routine went from nearly-flawless in 11.1 to mildly annoying in 11.3, arriving to moderately obnoxious in 11.4. What happened? Same as with Microsoft, poor installation workflow is to blame. One can always feel when desktop support people take over workflow tasks from server admins.

Quick Review: Boxee Box

Some of the technical issues with Boxee Box could have been fixed if the dev team was paying more attention to addressing the bugs rather than adding “features” of dubious value. In the final analysis, for the price and ease of use, Boxee Box is the best in its class and price range. You just need to be mindful of its limitations and buy it in hope of future improvements to its usability.

Simple Host Monitoring with SSH

Sometimes you just need something very simple to monitor a server or an application on a temporary basis. A basic ping monitor is fine, but it will only tell you if a server is responding on the network. It will not tell you if there is some other problem on the system. The script below relies on passwordless SSH setup to periodically log into the monitored nodes and check on their health by executing a local or remote script.

Windows Network Troubleshooting Script

I try my best to stay away from Windows. I wish my clients did the same. The usual difficulty of troubleshooting elusive network performance problems is amplified many-fold when there is a Windows computer at the end of the line. With Unix it’s relatively simple: run tests “a”, “b”, “c”, etc and follow the familiar process of elimination. With Windows in the picture the number of steps uses up all of the English alphabet and spills over well into the Russian one. And when you finally reach step “я”, you have to pull out your Chinese dictionary.
