You are reading directly from the md device and there is no matter what is actually there. heh. I read that as crypt device and it is MD directly, sorry for confusion. Seems my brain is still in different timezone :) yes, this test has nothing to do with crypt. Anyway, it is interesting that the problem is there even without crypt, perhaps you should ask on linux-raid list then. for badblock - I guess it just submits all IO from one cpu, so only one core is used for encryption in fact. There applies the same what I wrote before. Milan _______________________________________________ dm-crypt mailing list dm-crypt@xxxxxxxx http://www.saout.de/mailman/listinfo/dm-crypt
