Cannot shutdown/reboot Meteohub on VirtualBox

[rune]

When issuing a shutdown or poweroff from the commandline, Debian fails with:

Unmounting local filessystems...umount2: Device or ressource busy
umount: /data: device is busy
umount2: Device or resource busy
umount: /data: device is busy
failed.
Will now halt.
Shutdown: hda

but it never shuts down. Any idea of how to fix this?

I'm running on Virtualbox as well, and have not experienced this kind of issue.

Sounds like a process is not being killed.

Might want to check with

Code: Select all

fuser /data

which process is using the filesystem.

Hi,

fuser /data does not show any processes at all .

I also have an issue with Meteohub halts the datacollection from my Oregion WMR100 + RFXcom. It looses connection all together and seems to crash somehow.. Despite the VM saying "stopping", it never stops so I need to reboot the host PC.

Out of curiosity which OS do you use for you VirtualBox? I'm on Ubuntu 12.04 LTS.
I was also looking into upgrading Debian (to "Lenny" I think), as I thought a newer version was better for virtualization, but I don't know if it would help.

Hi,

My virtual host is Opensuse

Code: Select all

(openSUSE 12.3 (x86_64)
VERSION = 12.3
CODENAME = Dartmouth

Virtualbox is 4.1.32. Yes, I know it's old, but I do not have the guts/time to upgrade and it runs pretty stable (4 guest environments including MH).

I'm using, amongst other, RFXcom and I do not have disconnect issues.

[rune]

I'm on Vbox 4.3.20, so the latest but it seems strange that a new version shouldn't work .

Did you convert the VMware image as I did? I haven't changed any settings afterwards but maybe there's bit and pieces which should be altered in the VM. Of course Meteohub is upgraded to the latest version and the entire configuration from my ALIX.1D has been restored on the VM version.

[YJB]

Hmm, I can't remember the exact steps.

This is how my config currently looks like:

This is what I gathered from my notes (after getting the VM up and running):

Code: Select all

## Meteohub-VM
- Stop logging on the alix1d
- Stop logging on the VM
- Disconnect the RFXcom
- alix1d # scp -rp /data/* root@meteohub-vm:/data
- alix1d # meteohub scp -rp "/home/meteohub/meteohub.conf root@meteohub-vm:"/home/meteohub/meteohub.conf
- Add all the crontab entries inside the meteohub marked boundaries 
- Connect the RFXcom to the VM
- Reboot meteohub-vm and resume operations

[rune]

Thanks!

There's a couple of differences between our configs. I'm not sure what the impact is:

ACPI: on

Mine is off

PAE: off

Mine is on

RTC: UTC

Mine is not

Nested Paging: off

MIne is on

Video redirection: disabled

Mine is enabled

So there's absolutely a couple of areas which I could look into. I've just created a new VM with Meteohub and did not restore the backup. This seems to be more stable, so maybe there's a config issue somewhere.. Thanks so far!

Hmm, doesn't seem to work very well. E.g. if I restart data logging it always ends up saying:

error receive data from socket 127.0.0.1:5555: Resource temporarily unavailable
Warning: Data logging has been halted.

and I need to restart the entire VirtualBox

The only thing I cannot seem to change which you have disabled is the "Acceleration VT-x/AMD-V" which I need to have enabled, otherwise Meteohub doesn't start at all. Might turn out, than I need to go back to the hardwarebox afterall

[rune]

I seem to have found the problem, which relates to my Oregon WMR100N station. Whenever that is connected and used my Meteohub, I experience a lot of problems, like cannot reboot, data logging fails etc.

By the looks of it, Meteohub does not close the connection properly so /data "hangs" at shutdown and I cannot stop/start data logging.

@Boris: Is this something you perhaps could look into?

[YJB]

Hi,

I would say 1st look at the USB side of things: like a different cable, a shorter cable, use an USB hub.

I'm also not sure what your setup is: initially your were referring to RFXcom, now it appears to be a "plain"connection to the weather station?

[rune]

Hi,

Actually I have both my WMR100 and RFXCOM connected (WMR is better at picking up the PCR800 rain sensor + it has barometer), but RFXCOM is more stable + better range, so I combine the two.
The cable was also used when my WMR was connected directly to ALIX.1D and it worked without problems (so did Meteohub ), but I could try to find another. It's pretty clear that things go wrong when the WMR is connected.
