Debian Installer Multipath Support
30th January 2009
The current state of multipath support in Debian Installer's RC2 for Lenny is documented here. The netinst works fine if you use the patched grub (#442382). Unfortunately the CD images are currently broken due to missing libaio udeb.
The easiest way to get the patched grub into your system is via http://tinyurl.com/mpgrub/inst_i386.sh as described in the README.
The recently updated multipath-tools 0.4.8-14 support disks >2TB and also work with kernels more recent then Debian's 2.6.26.
