Reisers, I have three questions related with this 4 months old issue.
- Still reiser2 or reiser4 do not support "on demand" bitmap read? - What is the supporting block size on reiser2, and reiser4? - I am going to build one big volume(LVM) out of 8 IDE disks and make reiserfs on it. Where does the system write the meta data(super block, bitmap,..) into? Will it copy the same meta data on each disk?
