Use ReiserFS in CentOS 5

CentOS 5 doesn’t support ReiserFS by default. You need to install the kernel with reiserfs support and reiserfs utilities (such as mkfs.reiserfs) from “centosplus” repository.

However, “centosplus” in not enabled by default and kernel update is disabled in /etc/yum.conf in some customized versions. So we shall enable kernel update first

1. edit /etc/yum.conf, comment the line “exclude=kernel*” out.

2. install kernel and utilities from centosplus repo

[root@xok.la-LAN ~]# yum --disablerepo updates,base --enablerepo=centosplus list 'kernel*'
