Hi
some month's ago i had a running LVM over sofware RAID-0 setup
i have currently also a normal VG ( PV's are normal partitions) wich has
no troubles with ext2 nad reiserfs
but the new VG (containing striped LV's) which is
/dev/hdh10
/dev/md6 linear software RAID
/dev/md7 linear software RAID
i can not format with ext2 or reiserfs , when i try mke2fs mkreiserfs
they segfaults
because of the troubles with ext2 and reiserfs i think that i can not be
sure that everything with the LV's works
but probably i'll try cpio-ing my installation over it and give it a try
i'm running ABIT's BP6 2xCelleron533 512Mb RAM 2xWD 30Gb 1xMaxtor 40Gb
raidtools-0.90 lvm-1.0.1rc2 e2fsprogs1.23 1.24 1.24a reiserfs-progs-3.x.0j
and one more question about the min-max
i don't speak "C" can you tell me how to do it with pre linux-2.4.9patches
wich i wont to aply to linux-2.4.10pre2 and they are giving me problems
with min-max definition
