Centos 7.6 and n5550-0.6

[isketerol64]

Hi:

I am having issues with gpio leds and version 0.3 so I wanted to try the 0.5 version. I am ending up with a compile error:

• gcc -std=gnu99 -Os -Wall -Wextra -pthread -o freecusd alert.c conf.c cputemp.c disk.c err.c lib.c loadavg.c main.c pic.c proc.c raid.c smart.c sysfan.c tty.c -lcip

  ^
  compilation terminated.
  error: Bad exit status from /var/tmp/rpm-tmp.XpGF8y (%build)

I tried installing the libatasmart src rpm with no luck.

I really appreciate your help in building this module. Centos is a far better OS on the Thecus NAS than what was being provided to use.

Thanks in advance.

Sorry, I meant version n5550-0.6

[isketerol64]

Installed libatasmart-devel-0.19-6.el7.x86_64 to resolve the build errors.

On reboot, freecusd is dying and none of the leds light up.

I went back to version 3 in which freecusd works, but the LEDs don't work. The messages on the LCD report 3 drives in the NAS when there are 5, and the cpu temperature reports as unknown. The red error light also is illuminated. The messages that do appear are useful - indicating the overall health of the unit.

I'm happy to help debug this if there is any interest. This is a great utility for the N5550.

Thanks.

Have you added acpi_enforce_resources=lax to the kernel parameters (section 12 of the quickstart)?

[isketerol64]

Hi:

Here's my /etc/default/grub

GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="crashkernel=auto rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet acpi_enforce_resources=lax"
GRUB_DISABLE_RECOVERY="true"

[ipilcher]

I don't see the acpi_enforce_resources in the abrt-cli output above. Have you done the necessary incantations to make your config change effective? (I still use GRUB 0.9, so I'm not 100% sure what the incantation is.)

[isketerol64]

Hi:

The issue comes down to Centos 7.6 installing a UEFI kernel, thereby the commands to update grub need to change as shown following. I have the n5550-0.6 version working now. I did uninstall the sgpio package which may or may not have been causing conflicts as well. I did make the same change for the GPIO_BASE at 451 as another person has reported.

The grub2-mkconfig command is:

grub2-mkconfig -o /etc/grub2-efi.cfg

and should be run once the /etc/default/grub file has been updated.

The issue I thought I had with the display of "3" in RAID pertains to having 3 RAID volumes. The full set of 5 drives is correctly shown. I has simply replaced the Thecus DOM with a new 32 GB DOM and installed Centos without changing the RAID arrays. The original 3 volumes are still there.

The drive light on the first drive bay does not light up green by default for some reason, but it will show the red and the orange status lights when the /etc/freecusd file is updated. I had been a little concerned that there was a fault with the drive as I was used to seeing all of the lights active to show activity across the array.

So all being said and done, my sanity has been restored once I had realized that the UEFI config needed to be used.

Much thanks again for creating this software and maintaining it. It does make the Centos install much more compelling than other distros with LCD module working,

Hi,

im new to Github and dont know if this is the right place for my issue. Sorry if not...

First of all, thank you very much for this piece of software! My n5550 with OS7 Beta died with a broken DOM after a WOL attempt this week and thanks to your software i have hope to get it full up and running again with CentOS. Last status is data is readable and the hardware runs pretty good with CentOS, now i hope to get the LCD and status LEDs running.

I installed the latest CentOS 7.7 with kernel-plus-3.10.0-1062.1.1.el7.centos.plus.x86_64, libatasmart-devel-0.19-6.el7.x86_64 to compile version 0.6, libcip-0.1.1.5 and hddtemp-0.3-0.31.beta15.el7.x86_64 packages without any problem on my NAS.

But i got the same issues with 0.6 like user isketerol64 in this thread. I set "acpi_enforce_resources=lax" (and in my case "video=LVDS-1:d" to get the external screen running) in /etc/default/grub and got it running with grub2-mkconfig -o /etc/grub2-efi.cfg. This seems to work cause my screen is running fine and i got no resource conflict in "dmesg | grep gpio" only the warning at drivers/gpio/gpiolib.c:177 gpio_to_desc+0x94/0xe0.

So the GPIO Error on startup seems to be gone but freecus is still dying and i get a message of a tainted kernel if i start freecusd.service after boot manually with systemctl start freecusd.service. Not even the GPIO_BASE setting to 451 in n5550_board.c or the removal of the sgpio package has been helpfully. I tried the alternate smart and hddtemp method from #13 also without luck.

The only thing which seems to work is the System FAN setting, cause it starts running at full speed at boot. and i found out if i start the install_n5550_board method from /usr/lib/modprobe.d/n5550.conf manually i get the second to fifth HDD LEDs on with static green, first one remains off, but no blink on disk activity. Also the LCD is starting to show HDD temperature till the next reboot.

Help would be much appreciated.
I can provide Logs if needed and if i get it running i would document it here.

Hi Schwaus -

This probably should have been a new, separate issue, but no worries.

What is the output of cat /proc/cmdline on your system?

[Schwaus]

Hi,

thanks for your reply.

cat /proc/cmdline output is:

[root@nas administrator]# cat /proc/cmdline
BOOT_IMAGE=/vmlinuz-3.10.0-1062.1.1.el7.centos.plus.x86_64 root=/dev/mapper/cl-root ro rd.lvm.lv=cl/root rd.lvm.lv=cl/swap acpi_enforce_resources=lax video=LVDS-1:d rhgb quiet

If i run systemctl | grep freecusd to see if the service is running i get:

[root@nas administrator]# systemctl | grep freecusd
●freecusd.service                                                                                                       
 loaded failed failed    Thecus N5550 NAS monitoring daemon

When i try to restart the service, SE-Linux Bug-Reporting tool is popping up and gives me the message of a tainted kernel with GOE flags and module n5550_ahci_leds.

[ipilcher]

Your kernel command line looks OK.

So, can you describe exactly what issue you're seeing? Are you getting the error about gpio_ich resource conflicts or something else?

Also, what does journalctl -b -u freecusd say?

It's worth noting that I've never used UEFI on this thing. (I absolutely loathe grub2, so I switched the system to legacy boot mode before I even installed CentOS on it.) It's possible that the UEFI firmware sets up the hardware differently.

[Schwaus]

Ok so the issue is that my NAS is starting normaly, and i hear that the System-FAN start spinning at highest RPM, as it should in default-setting, but neither the green HDD LEDs, Warning LEDs on the left or the LCD Screen is functional.

When i run systemctl | grep freecusd right after login i dont get any output, but journalctl -b -u freecusd shows:

[root@nas administrator]# journalctl -b -u freecusd

I dont have any gpio_ich resource conflict, only this warning:

Maybe i reinstall Centos in legacy boot mode and give it a try.

[Schwaus]

Hi,

got some new information on this. I removed version 0.6 and installed version 0.3 last night, didnt reboot and started the service with systemctl start freecusd.service manually. After that all green HDD LEDs began lightning and the LCD Screen shows information.

Then i upgraded to version 0.4, 0.5 and 0.6 all without reboot but with service restart between the upgrades. Everything looked fine until i did a reboot of the NAS, then the service went to failed state again. So i think it has something to do with how the service is loaded.

Then i reinstalled CentOS in legacy boot mode without UEFI but i got the same behavior. Could there be something wrong with my installation routine or my bios settings?

I did a systemctl status freecusd.service and got this:

[root@nas ~]# systemctl status freecusd
● freecusd.service - Thecus N5550 NAS monitoring daemon

Edit:

Did a restart of the service and a journalctl _PID= to see the errors of the MainPID today:

So it seems there are some Directories/GPIO missing under /sys/class/gpio/ and /sys/class/leds/ but i can not create them manually. Is there a script which creates them in your Software? I installed version 0.3.1 for testing purposes again and this seems to create the missing GPIO31 and gpiochip16 and deletes them when i install 0.6 and reboot.
