Hi, sorry for reopening such an old bug, but I found it via Google searching for my problem and the information in here was very helpful. So I thought it would be a good idea to put this related information here.
The problem: The solution explained here is not working for me. I set both variables I found to "disabled": # udevadm info -q all -n /dev/sda |grep SMART E: ID_ATA_FEATURE_SET_SMART=0 E: ID_ATA_FEATURE_SET_SMART_ENABLED=0 But the drive is still polled. I verified it using # udisksctl monitor Distribution is openSUSE 13.1 and udisks2 version is 2.1.1. Any hints what is wrong here? I have a some machines with SSDs for OS and additional Western Digital drives that would be in standby most of the time if udisks wouldn't poll them. Standby timeout cannot be set low enough for the drives. With udisks1 disabling polling was working as described in this bug and I was able to use smartd to check the SMART status, because it is possible to - adjustable polling time and - polling is working on drives in standby without waking them up. cheers, Jochen -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/379780 Title: CD-ROM polling on some Optiarc drives causes high CPU usage Status in The Linux Kernel: Confirmed Status in abstraction for enumerating and managing block devices: Confirmed Status in “linux” package in Ubuntu: Invalid Status in “udisks” package in Ubuntu: Fix Released Bug description: Binary package hint: udev Before I upgraded the udev version of jaunty from 141-1 to 141-1.1, top reported about 2% total cpu usage when idle.
