I'm using hdparm -Y /dev/sda1 to force one of my HDDs to sleep upon system startup, but some process accesses it and it is turned on again. How can I disable the automatic startup of HDDs?

They are NOT listed in my Startup Applications under preferences. For example, pidgin. Pidgin automatically starts at each login even though it is not in the startup apps nor can I find an option in pidgin itself. Tomboy is another. I always get an error that tomboy cannot be added to my panel when I restart. The error in the tomboy panel log is that tomboy is already running.

View 1 Replies View RelatedOne of my ubuntu 10.04 boxes starts apache2 server automatically at boot. I know from the output of the command:
Code:
sudo /etc/init.d/apache2 status
I can't remember even setting that up, and I don't think it does so by default, since my other box in fact does not even have apache2 server installed. I can stop the server once I login, but is there a way to stop it from automatically starting the server, or even better, completely uninstall the daemon. I tried
Code:
sudo apt-get remove apache2
but that does not work. I guess the daemon is part of some bigger package.

View 3 Replies View RelatedI've been using ubuntu for the past year now but unfortunately I have to confess I never had to compile anything from scratch. I bought a new intel SSD drive and I've been running some benchmarks on it with various fs. The new hdparm version has a few features that I'd like to test (TRIM/wiper) but I don't know how to install it as it's not in the repositories. I've been googling for almost 4hrs now but I still haven't found a way to do it.
I've downloaded the tar.gz file from sourceforge and I've decompressed it. Inside, it was a debian folder but there was no .deb file in it. Anyway I did a "make hdparm" and it compiled with no errors. It gave me an "hdparm" executable which works fine if I call it with the full path. what's the proper way to install it in place of the already apt-get installed package?
Im wanting to put HDD's to sleep using hdparm after 20min of activity (a 4x disk raid5 array and two single disks). I have edited /etc/hdparm.conf, adding the following lines at the end of the file:
Code:
#6TB RAID5 POWER DOWN
/dev/disk/by-id/scsi-SATA_ST32000542AS_5XW0T1R6 {
spindown_time = 240
[code]....
Code:
sudo hdparm -y /dev/disk/by-id/scsi-SATA_SAMSUNG_HD501LJS0MUJDWQ411622
The HDD's will sleep with out issue. Ive looked around my log files and cant seem to find anything to do with hdparm, or the HDD's sleeping. Have I make a mistake in the .conf file? Is there some place hdparm logs, or if I can activate some sort of verbose mode? Or does hdparm need to be activated on boot?
EDIT: I'm using ubuntu 10.04.1 x64 last updated today.
can hdparm do secure erase on just a partition or does it have to be the whole drive?

I have connected it up instead of the dvd drive and booted with it as slave. The OS can access it using hdparm -I /dev/hdb, but it showing as locked I have the key which is:

I'm trying to make sure I don't screw anything up. When I type in the following into the terminal:
sudo hdparm -M 128 /dev/sda
Are the changes permanent, even if I restart? If not, how can I make sure it is permanent? I've read of going into the /etc/hdparm.conf file and editing it, but what exactly do I type and where should it be put in the file?
I have hdparm running and see the reading in gkrellm

I have SSDs connect to my Linux machine through the LSI SAS/SATA 1068E controller. I've been trying to issue a ATA secure erase command to my SSDs, but I keep getting error. In fact even hdparm -i fails.
# hdparm -i /dev/sda
/dev/sda:
HDIO_DRIVE_CMD(identify) failed: Invalid exchange
HDIO_GET_IDENTITY failed: Invalid argument
Initially I thought there was some kernel configuration issue, so I tried connecting a SSD to the on board SATA and I no longer get errors. The secure erase worked. It seems there is some compatibility issue with hdparm and the LSI controller/driver I'm using. Any way to make hdparm play nice with my LSI controller? Has anyone had success getting hdparm to work with drives connected to an LSI controller?
Additianal info:
Linux Kernel: 2.6.30
hdparm: v9.27
LSI driver: Fusion MPT SAS Host driver 3.04.07
I have set up a hdparm configuration file ( /etc/udev/rules.d/50-hdparm.rules ) with :
Code: Select allACTION=="add", SUBSYSTEM=="block", KERNEL=="sda", RUN+="/usr/bin/hdparm -B 255 -S 0 /dev/sda" .
This works correct when I power on my system, however after waking my computer from sleep mode , /dev/sda appears to operate with APM .
Is there a way I can make this setting to be persistent ,i.e. APM disabled when waking up from sleep mode?
I am running Debian Jessie x64.
I've just put together a 10.04 server using a GA-D525TUD atom board. I've installed gnome desktop too. I'm trying to get 4 sata drives to go into standby, but hdparm seems to be ignoring the settings. If i issue hdparm -y /dev/sdx the drive duly goes into standby and stays in standby until accessed. I've put entries in rc.local along with the hdparm.conf settings, but still no joy.
Hdparm.conf:
/dev/sdb {
spindown_time = 244
}

I have some general question with with quite an impact for the system I use I have a media server with 2 raid1 mirrors of 2 1 To disk aggregated with lvm and used by a big 2 To ext3 partition.A few days ago, munin (awesome!) started to send me notifications about smart attributes of some disks. Fyi, here's my hdparm.conf:
/dev/sda {
spindown_time = 54
}
/dev/sdb {
[code]...
regarding reliability and disk longevity, is it recommended to have them spin down while not used (most of the day, as these are storage unit for movies, pictures, documents..) or let them spin whatever.. ? Those are WD green and according to Tom' Hardware, the consumption is only slightly greater in idle compared to standby. The other question, (boat one as we say in french ) what is the best configuration here ? My 2 raid 1 stripes, or a raid 5 ? I know that two disks kill the raid 5, and they have to be of the same stripe to kill the lvm on the raid1, but what are the odds ?
I have tried issuing this command:
[root@C5 ~]# hdparm -a 256 -d 1 -r 0 -k 0 -u 0 -c 1 -A 1 -K 0 -P 0 -X 66 -W 0 -S 0 /dev/sda
/dev/sda:
setting fs readahead to 256
setting 32-bit IO_support flag to 1
[code]....
Note that setting most of the parameters fails - and it still appears to be in 16 bit PIO mode. Am I using the wrong tool here - or incorrect parameters - or are the results misleading? Is there some other interpretation?
On a Powerbook G4, I set hdparm to set the filesystem readahead (-a) to the maximum 2048 on boot. This produces a visible increase in performance... But today the hard drive started acting up - first generating I/O errors when trying to access various system binaries, and the second time bringing the desktop to a standstill and emitting loud clunking noises.In both cases the drive worked normally after a reboot... Even so, these are not what I'd consider good signs. However, the computer was working perfectly up until now, so I'm wondering if my tweaking was responsible. Can overly aggressive filesystem readahead settings damage an IDE hard drive?
View 2 Replies View RelatedI'm testing OpenSUSE 11.3 on a server and I'd like to disable the write cache on all of my drives. In Ubuntu Server I was able to accomplish this with hdparm by adding the appropriate settings to /etc/hdparm.conf
As far as I can find the only thing that OpenSUSE offers is /etc/sysconfig/ide which allows you to force particular DMA modes. I could just put the hdparm commands in /etc/init.d/boot.local but I'd prefer to do it the right way if there is a right way to do this in OpenSUSE.
I installed OS11.4 on my old laptop, Compaq Armada E500., 512MB RAM, ATI Rage Mobility. During installation I chose "minimal server" and added some development packages, lxde and a little more. I chose to start in runlevel 3 which is full networking without X. Still, when computer is booted it tries to start Xorg which doesn't work because of some problem w driver. The start-up seems to stop there, it never loads completely - seems most things in runlevel 3 are not started (see below) I can manually login on laptop and fix it - but never permanently, same thing again after reboot.
I have checked /etc/inittab & yast - both states default runlevel is 3. I have checked services to be started both directly, browsing directory /etc/rc.d/rc3.d/, and with YaST, it is very clear X should not load during boot. But, as said, it does.. I don't really care about the driver problem right now, I can fix that later when I have more time. So how do I stop X from getting started automatically?
More info, if needed: The installation also stopped with message on tty1 "Starting YaST2" and tty8 showing errors with graphics driver (mach64). The system seemed to be installed though, so I simply rebooted (issuing "reboot" from tty2).
[Code]....
I'm not completely sure where it stops, network is configured but keyboard is wrong and mysql & everything after is not started, so somewhere between S02network and S06kbd. I'm going to use it as a server for testing purposes so no X is actually needed - however I do want to have X & lxde installed just in case, my Internet connection at home is terribly slow so I need most things I might need in the future installed today.
I know I need a better title, but don't have one.
The problem is when watching a video F15 Gnome decides to send me to the unlock screen. Think that's what it's called. So I have to type in my pass.
A little bit later, same thing. So how can I prevent it from happening?
Actually I'm not sure that it's swapping like mad: I've done more testing and it looks like there may some interference causing the noise that may be correlating with network usage. I'm accessing a MacMini (with MacOS X 10.4) from my Linux machine using VNC. My Linux machine has 4 GB of ram and I run a lot of various apps on it and I've got no issue at all. It's all snappy and don't hear the hard disk swapping/read/writing too often. Now with VNC, the hard disk is swapping like mad. When I'm moving things on the OS X desktop. So I was thinking of creating a ramdisk and forcing the temp VNC files to go into that ramdisk but the problem is I can't find any temp files.
I've attempted to do that:
#!/bin/bash
while [ true ]
do
lsof | grep vnc
done
The VNC version I'm using is this one:
$ vncviewer -version
VNC Viewer Free Edition 4.1.1 for X - built Jan 30 2009 19:33:16

No matter how much data is coming from the Mac, there should be plenty of memory (4 GB of ram) so there's really no reason to swap like crazy.

View 7 Replies View RelatedI want to prevent grub-pc from automatically creating links to other operating systems on my laptop. Whenever there is a kernel update, grub.cfg ends with links pointing at my Windows 7 installation - I want to get rid of those links. At the moment I am doing that by manually editing the grub.cfg file and it has always worked that way.
