>What you said was inconsistent. loop3/md4 vs. loop1/md2
I will do that. Just as a "sort out" 3/4 were the examples on the page.
1/2 was what I actually used.
I start by rebooting my system to be sure.
cookiemonster:~/VMware# reboot
[removed useless info about system shutting down]
We log in, and I recreated the array (after zeroing superblocks)
mdadm --create /dev/md2 --chunk=64 --level=raid1 --raid-devices=2
/dev/hde1 /dev/hdf1
cookiemonster:~# mdadm --detail /dev/md2

So far, all is well, log shows:

And THEN I get the below (but mind you, the FS create continues, until
"Writing inode tables: Done" and then the terminal freezes. But
processes starts to dies with OOM ( still have plenty RAM left).
