Red Hat RHEL, CentOS, OEL 4 & 5 SAN filesystems go readonly !

Wednesday, June 11th, 2008

Apparently there is a problem in the kernel used in Red Hat RHEL 4&5, CentOS 4&5, OEL 4&5, SUSE, Ubuntu 7 and other GNU/Linux distributions that causes EXT2 EXT3 filesystems that are residing on SANs to randomly go read-only !

However if you are using kernel 2.6.18-53.1.21+ or 2.6.22+ you should be ok !

Howto use yum excludes to prevent kernel updates breaking VMware kernel modules

Friday, February 15th, 2008

If you are using CentOS 5 , Oracle Enterprise 5 or Red Hat Enterprise 5 as a VMware host or guest you can edit /etc/yum.conf and add a line

exclude=kernel*

this should prevent yum updating your kernel and thus breaking vmware services modules in vmware server and vmware services modules in vmware guest tools
