Hi, I've written two small howtos, and would like to contribute them to the CentOS Wiki. The first one is "How to install CentOS 5 on software partitionable mdadm RAID1", and the second one "How to repair a software mdadm RAID5 with two or more failed disks (if you know that information is still on the disks and readable)". I think that the first one should be somewhere like wiki.centos.org/HowTos/Install_On_Partitionable_RAID1 with a reference from wiki.centos.org/HowTos and the second one should be wiki.centos.org/TipsAndTricks/Reparing_RAID5_With_Many_Failures with a reference from wiki.centos.org/TipsAndTricks My account name on the wiki.centos.org is LevShamardin, and the untranslated russian versions of these articles are available in my blog at http://abbot2.blogspot.com/2009/04/centos-53-partitionable-raid1.html and http://abbot2.blogspot.com/2009/04/mdadm-raid5.html With best regards, Lev.
