Hi and thanks to those who answered. Since nobody stood forward and told me I'm going to do something stupid, I took some courage, and pulled my little stunt. As one could expect, it worked like a clockwork. I never did an exhaustive test, but settled for what I really needed to do, which was storing around 20 GB of data in files of different sizes and shapes, in the secured image. Which is not a negligible operation.
I kept a look on /var/log/messages and nothing special appeared there. The only annoyment was that the computer becomes extremely sluggish during a heavy copy operation (despite ionice), but that is also true when going directly on the single-encrypted LVMed RAID disk (or maybe this is true on whatever disk?). I wrote a small script which turns a plain file into an encrypted ext4 image. I prefer having a script wipe out my disk because I got the bash programming wrong over having the same effect because of not being concentrated for a split second. You can have a look, even try it out and then NOT blame me: http://billauer.co.il/blog/2010/09/encrypted-disk-image-dm_crypt-luks/ Gmar Hatima Tova, Eli -- Web: http://www.billauer.co.il _______________________________________________ Haifux mailing list [email protected] http://hamakor.org.il/cgi-bin/mailman/listinfo/haifux
