hd-idle not starting on Ubuntu 20.4.01 #37

cannondale0815 · 2020-12-05T03:11:25Z

I tried installing the latest 1.11 amd64 package on Ubuntu 20.04.1 LTS. No matter which command line option I choose, even when I just use -h, it only prints the following and then hangs:

symlinkPolicy=0, defaultIdle=600, defaultCommand=scsi, debug=false, logFile=, devices=

I previously had the original hd-idle from C. Mueller installed on my system (built from source). Before installing this new version of hd-idle, I made sure to remove the old binary to ensure there are no conflicts, but unsure if there are any other residual files that may cause issues on my end.

I also tried building this version of hd-idle from source but having the same issue above still. I can confirm that on my system, /proc/diskstats is present.

Would love to use this version of hd-idle on my Ubuntu system, but am stuck. Any help is appreciated :)

Hi @cannondale0815

I'm not sure what you mean by "hangs". hd-idle runs in the background.

Could you please share the results of the following commands?

ls /dev/s*
tree /dev/disk/
cat /etc/default/hd-idle

@adelolmo by hangs, I mean it outputs that one line I mentioned above and doesn't return to the command prompt.

Here is the output of the commands you requested:

# defaults file for hd-idle

# start hd-idle automatically?
START_HD_IDLE=false

# hd-idle command line options
# Options are:
#  -a <name>               Set device name of disks for subsequent idle-time
#                          parameters (-i). This parameter is optional in the
#                          sense that there's a default entry for all disks
#                          which are not named otherwise by using this
#                          parameter. This can also be a symlink
#                          (e.g. /dev/disk/by-uuid/...)
#  -i <idle_time>          Idle time in seconds.
#  -c <command_type>       Api call to stop the device. Possible values are "scsi"
#                          (default value) and "ata".
#  -s symlink_policy       Set the policy to resolve symlinks for devices.
#                          If set to "0", symlinks are resolve only on start.
#                          If set to "1", symlinks are also resolved on runtime
#                          until success. By default symlinks are only resolve on start.
#                          If the symlink doesn't resolve to a device, the default
#                          configuration will be applied.
#  -l <logfile>            Name of logfile (written only after a disk has spun
#                          up). Please note that this option might cause the
#                          disk which holds the logfile to spin up just because
#                          another disk had some activity. This option should
#                          not be used on systems with more than one disk
#                          except for tuning purposes. On single-disk systems,
#                          this option should not cause any additional spinups.
#
# Options not exactly useful here:
#  -t <disk>               Spin-down the specified disk immediately and exit.
#  -d                      Debug mode. It will print debugging info to
#                          stdout/stderr (/var/log/syslog if started as with systemctl)
#  -h                      Print usage information.

@cannondale0815

by hangs, I mean it outputs that one line I mentioned above and doesn't return to the command prompt

I suggest you have a look to the section Run hd-idle in the README. Specially the part that mentions If the Debian package was installed.

Also, your configuration in /etc/default/hd-idle is missing the entry HD_IDLE_OPTS. Please check the configuration section. This is the original /etc/default/hd-idle content in case you need it.

@adelolmo For now, I am just trying to run it on the command line, not as a service, And when I just say hd-idle -h, it only shows:

user@NAS:~$ sudo /usr/sbin/hd-idle -h
symlinkPolicy=0, defaultIdle=600, defaultCommand=scsi, debug=false, logFile=, devices=

And doesn't return (I have to Ctrl+C to get back to prompt). Am I misunderstanding how this version of hd-idle has changed from the original one? That one, I could just invoke from the command line.

For comparison, this is what the older version (from C Mueller) shows:

user@NAS:~$ sudo /usr/local/sbin/hd-idle -h
usage: hd-idle [-t <disk>] [-a <name>] [-i <idle_time>] [-l <logfile>] [-d] [-h]

It depends on what's you expectation here. What are you trying to achieve?

hd-idle works like a service: it's started and it runs until stopped.
The only usecase that returns to the prompt is when invoked with the flag -t to spin down a single disk.

As a side note: I noticed a bug invoking help via -h flag. I'll fix it in the next release.

cannondale0815 · 2020-12-05T14:40:24Z

Ah -- I guess that may explain it. Since I have been using the old hd-idle for a few years, I was stuck thinking I could just invoke your version the same way on the command line. And the first thing I always do is to have a program print its own help screen to familiarize myself with it. So let me go ahead and configure it to run as a service and if I run into any issues, I'll report back -- thank you!

I set it up to run as a service with systemctl and it works great, so thank you for the explanations above, I appreciate it!
