** Summary changed: - [natty] Cannot spin down hard drives + [natty] Cannot spin down hard drives while APM_level=254
** Description changed: Binary package hint: hdparm + Some hard drives (tested with Samsung HD154UI) refuse to spin down on + demand (hdparm -y and -Y options) or on inactivity timeout (-S) while + the APM level (-B) is at 254. Setting it to another value (tested 255 + and 253) makes the drive respect the set spindown time and spin down on + demand as well. + + ----------------------------------------- + Old description: On an update natty ubuntu-server installation (hdparm version 9.32-1ubuntu1) with nothing accessing the hard-drives running, I can't get them to spin down. The drives (sd[ab]) are in an LVM setup but only used for 2 data-directories, the system itself is on a USB flashstick (sdc) mounted directly: # mount /dev/sdc1 on / type ext4 (rw,errors=remount-ro) ... /dev/mapper/DATA_VG-DATA_LV on /data type ext4 (rw) /dev/mapper/DATA_VG-ZALOHY_LV on /zalohy type ext4 (rw) # pvdisplay --- Physical volume --- PV Name /dev/sda1 VG Name DATA_VG ... --- Physical volume --- PV Name /dev/sdb1 VG Name DATA_VG ... hdparm -y seems to do nothing at all, while hdparm -Y seems to put the SATA links to sleep: Jan 10 19:32:11 johny kernel: [13313.493918] ata3.00: exception Emask 0x0 SAct 0x1 SErr 0x0 action 0x6 Jan 10 19:32:11 johny kernel: [13313.506875] ata3.00: waking up from sleep Jan 10 19:32:11 johny kernel: [13313.514994] ata3: hard resetting link Jan 10 19:32:12 johny kernel: [13313.832117] ata3: SATA link up 1.5 Gbps (SStatus 113 SControl 300) Jan 10 19:32:12 johny kernel: [13313.845403] ata3.00: configured for UDMA/133 Jan 10 19:32:12 johny kernel: [13313.845439] ata3: EH complete Jan 10 19:32:12 johny kernel: [13313.852572] ata5.00: exception Emask 0x0 SAct 0x1 SErr 0x0 action 0x6 Jan 10 19:32:12 johny kernel: [13313.865560] ata5.00: waking up from sleep Jan 10 19:32:12 johny kernel: [13313.873618] ata5: hard resetting link Jan 10 19:32:12 johny kernel: [13314.192119] ata5: SATA link up 1.5 Gbps (SStatus 113 SControl 300) Jan 10 19:32:12 johny kernel: [13314.205402] ata5.00: configured for UDMA/133 Jan 10 19:32:12 johny kernel: [13314.205436] ata5: EH complete ProblemType: Bug DistroRelease: Ubuntu 11.04 Package: hdparm 9.32-1ubuntu1 ProcVersionSignature: Ubuntu 2.6.37-12.26-generic-pae 2.6.37 Uname: Linux 2.6.37-12-generic-pae i686 Architecture: i386 Date: Mon Jan 10 19:23:08 2011 InstallationMedia: Ubuntu-Server 11.04 "Natty Narwhal" - Alpha i386 (20110106) ProcEnviron: LANG=en_US.UTF-8 SHELL=/bin/bash SourcePackage: hdparm ** Tags added: apm ** Tags removed: i386 natty -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/701144 Title: [natty] Cannot spin down hard drives while APM_level=254 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
