I have tried this. I made the new 3.6.19 code. Ran a --rebuild-sb, seemed better. When I try to run a --check, it still says that it can not read the bitmap. So, is this problem with the reiserfs code in the kernel I am booting? I thought that we could get up to 16 TB. Is there a way to force a rebuild of the superblock. maybe delete it with dd at offset 64 ? something like this maybe ? dd if=/dev/zero of=/dev/VG01/lvol0 bs=1024 seek=64 count=1 (http://lists.suse.com/archive/suse-linux-e/2003-Dec/1731.html) Then rebuild the bitmap? This might be a bit crazy....? Anybody got any ideas? Thank you so much for the assistance!
