Source: linux-2.6 Version: 3.1.0-1~experimental.1 Severity: normal I use dm-crypt on my system, and I have an SSD. The underlying disk device, sda, has rotational=0:
~$ cat /sys/block/sda/queue/rotational 0 However, the device-mapper devices have rotational=1: ~$ head /sys/block/dm-*/queue/rotational ==> /sys/block/dm-0/queue/rotational <== 1 ==> /sys/block/dm-1/queue/rotational <== 1 ==> /sys/block/dm-2/queue/rotational <== 1 The device-mapper devices should inherit the setting for "rotational" from their underlying devices. - Josh Triplett -- System Information: Debian Release: wheezy/sid APT prefers unstable APT policy: (500, 'unstable'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 3.1.0-1-amd64 (SMP w/4 CPU cores) Locale: LANG=C.UTF-8, LC_CTYPE=C.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of "unsubscribe".
