Hi, as I am building a new server I want to use loop-aes (like the last years) for all partitions on it. My current idea is to use for the HDDs (4-5) the following structure : RAID6->lvm->loop-aes->xfs. If I understood the FAQ entry number 20 from http://mareichelt.de/pub/texts.loop-aes.php#faq20 correctly this works without any problem. Actually I have already tested this setup in a virtual machine. Regarding performance the post, http://mail.nl.linux.org/linux-crypto/2008-11/msg00033.html, suggest to use the command line 'lvcreate -i N' to create the logical volumne. Reading the lvcreate manpage gives: ########### -i, --stripes Stripes Gives the number of stripes. This is equal to the number of physical volumes to scatter the logical volume. ########### Without much thought I tried to use the --stripes option on my RAID6 in the VM but it failed with the message: ########### Number of stripes (5) must not exceed number of physical volumes (1) ########### So what does this mean? Do I have to switch to a different RAID level (e.g. RAID10) to get a more multicore-using loop-aes system? As far as I understand every loop-device has one process/thread/whatever to do the encryption, right? Therefore on a multicore system you should have more loop devices in use to get more troughput ?
