dm-crypt: Thread moved from debian-user. Please comment. TIA, David I have a 1.5 TB SATA hard drive I use for back-up's. It has a single large partition encrypted with LUKS/ dm-crypt and formatted with ext4. I've noticed what appears to be single-threaded behavior when one process is performing a long-lived write to the disk (notably 'ssh user@host tar ... > backupfile.tar.gz') and another process attempts toaccess the disk (either read or write). This is tolerable for a back-up application, but would not be acceptable for multi-user, multi-process, and/or multi-threaded applications (file server, terminal server, web server, etc.).
Is this a fundamental limitation of LUKS, dm-crypt, and/or ext4, or something I've configured/ misconfigured? If a fundamental limitation, is there something I can substitute to eliminate the problem?Some manufacturers make hard drives with built-in encryption. Are these supported by Debian, Linux, or BSD?
