After eliminating swap my /dev/sdb still spins up about once an hour. I don't have any of the following installed: - hddtemp - sensors-applet - smartmontools
In "cat /proc/mounts" I don't see any references to /dev/hdb or UUIDs of any of its partitions. I tried monitoring disk access and got no indication of any process accessing /dev/sdb* when the disk spun up or at any other time. I used this script to monitor: echo 1 >/proc/sys/vm/block_dump while ( ! dmesg -c|grep sdb ); do sleep 1; done echo 0 >/proc/sys/vm/block_dump Is there any way I could "freeze" the kernel after issuing the hdparm -S/y/Y command so that I can be sure neither the kernel nor any process is able to access the disk? That way I could make sure it's not the disk itself or the controller which decides to spin up the disk. -- Hard drive will not stay in standby mode https://bugs.launchpad.net/bugs/180986 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
