[linux-lvm] raid1+lvm

right now, I am not yet sure, if this all is ok, I´ve learned quiet a 
bit about the LVM, and I remember, that it was not suggested to use 
swap on a lvm in former times, and it doesn´t matter if it is a swap 
file or a partition, since there could be bad things when memory is 
tight. Perhaps this is problem is removed - I never used swap on a 
lvm, but I did on a software raid1.

It would be perfect if that all would work, you built a system with 
two cheap IDE-disks or scsi if you´re rich - than one can build a 
small boot partition on both disks and with the rest of the disk one 
can make a soft-raid1 with the lvm on top.

I know I can do it, so I have root and swap and data on the raid, 
accessible via the lvm.  But would it work if mem is tight and the 
system load is high or could I run into a deadlock ?

Best regards
