Linux is the victim here, not the culprit. Ext3 will remount a filesystem as read-only whenever it considers I/O to that device to be unreliable, in order to protect the data (as best it can). The fact that this problem is impacting more than one VM indicates an underlying problem with the storage being shared by the ESX hosts. I don't know if this is SAN storage or iSCSI or NAS shares, but whatever it is, it's in trouble at the ESX level. Look in the VMware console for the device that's being used for the root filesystems of the problem VM's and fix it. Once that's fixed, the error messages at the guest level will disappear after the guests are rebooted. This is also what's causing the errors from the LVM commands like pvcreate.

Hello,
I was wondering if it would be possible to run two VMs one with services for IPv4 and the other one with services for IPv6. The main physical system would be connected to a IPv6 switch.
I think it should be fine but I would like to hear out your comments. (1 Reply)

SYNOPSIS
yum-versionlock [ package-name [ package-name]] ...
DESCRIPTION
yum-versionlock(1) is a Yum plugin that takes a set of name/versions for packages and excludes all other versions of those packages
(including optionally following obsoletes). This allows you to protect packages from being updated by newer versions.
The plugin provides a command "versionlock" which allows you to view and edit the list of locked packages easily.
yum versionlock add <package-wildcard>...
Add a versionlock for all of the packages in the rpmdb matching the given wildcards. yum versionlock exclude <package-wildcard>...
Add a exclude (within versionlock) for the latest versions of the packages in the available repos. matching the given wildcards. yum ver-
sionlock list
List the current versionlock entries. yum versionlock delete <entry-wildcard>...
Remove any matching versionlock entries. yum versionlock clear
Remove all versionlock entries.
FILES
/etc/yum/pluginconf.d/versionlock.conf
The system wide configuration file. See yum-versionlock.conf(5) for more information.
/etc/yum/pluginconf.d/versionlock.list
The default place to put package version lock information (one package and version per. line). The file takes entries in the follow-
ing format EPOCH:NAME-VERSION-RELEASE.ARCH See rpm(8) for more information on custom query formats. If the package does not have an
EPOCH the number will default to 0.
BUGS
There are of course no bugs, but should you find any, you should first consult the FAQ section on http://yum.baseurl.org/wiki/Faq and if
