T4 can't open on desktop Mark 2

[csutak40]

OK I have old problem, new version. I wrote before about not being able to open T4 on the PC
Last night, I actually had it open when it crashed and refused to open again. Tried everything I can think of, (including mapping again) nothing worked (this time it won't open on 3 computers)

A friend suggested I try turning the Wiz off at the wall. Did that, during the reboot, I got an error that disappeared before I could read it (while scrambling for the phone) The only thing I read was that it was sorry… It then sat there with the boot-up screen, waiting…
Eventually I turned it off at the back again. That worked.
My friend (on the phone) suggested I try fixing the network on the Wiz. Navigated to the Network, clicked on Network Browser (only because I didn’t know which option I should click on) and I got the same error message, except it stayed there long enough for me to take a photo. It said it will disappear in 10 seconds (no wonder I couldn’t read it the first time!) but it didn’t. I had to restart it again, as it just sat there

It suggested to find the error log and send it to you. I actually found a thread explaining how to do that, but..
Trying the browser option didn’t work at all: Error 404: Page not found
So I tried the third option
MENU > Sources / Files) on the T4, - navigate to Internal Flash / home / root / logs.
There are no error logs there at all. I could only find the “execution log”

So, any ideas what I can do now?

ioerror: [errno: 28] No space left on device

I suspect at some point the T4 failed to mount its HDD and recordings have filled the flash memory, perhaps corrupting the firmware.

I suspect you'll have to reflash the firmware. Download 20191106 from here - https://beyonwiz.com.au/downloads/

That us consistent with the "No space on device" in the error log. The firmware flash filesystem is full, and that's where the crash logs are put by default.

Reload the firmware as Grumpy_Geoff suggested.

I agree that firmware flash has filled and that's causing the crash, but that shouldn't be caused by the HDD failing to mount. THe HDD mounts on /media/hdd and /media is a separate filesystem from the root filesystem.

It's a tmpfs (in-memory file system) with 64kb capacity. It'sso small because it only needs to hold the /media mountpoint directories:

Code: Select all

root@beyonwizt4:~# mount
...
tmpfs on /media type tmpfs (rw,relatime,size=64k)
...
/dev/sda1 on /media/hdd type ext4 (rw,relatime,data=ordered)
...
root@beyonwizt4:~# 

The cause of the root file system filling can really only be investigated by logging in to the PVR's commandline interface and poking around to see where all the space has gone. That interface will still run even if the enigma2 PVR app has crashed.

I pinched that idea from you

That may well have been incorrect. And I did say "that shouldn't be caused by the HDD failing to mount".

Yep, okay.
It's been mentioned before as a cause and not really challenged.
I'm not trying to be a smart arse.
Here warkus suggested it, and you and MrQuade appear to go along with the suggestion.

You suggested the HDD failing to mount and filling flash as a possibility here.
That case was definitely a recording in flash that drharry2442 managed to remove by disconnecting the drive and then deleting the recording from flash.

But in Judy's case it doesn't really matter, as her only avenue is a firmware reflash.

I'm not trying to be a smart arse.

Apologies if that's what it seemed like.

It's possible that using a tmpfs for /media is new (and designed to try to avoid the flash filling if the HDD doesn't mount & similar problems).

Thank you everyone.
Got two questions.
When I flush the firmware, can I use the backup?
The second question is, how do I "poke around" Or would that be above my paygrade?

[csutak40]

FWIW I just discovered that Ice TV can't access the Wiz either (the last timer I have is for Wednesday)

Other way round. The Wiz initiates contact with IceTV.

It just looks like it is failing to connect to the IceTV servers, so this indicates that the Wiz's network connection is just plain busted. Which explains why Windows couldn't connect to it too.

You can restore backed up setrtings to the Wiz after a reflash. I would encourage you to reflash sooner rather than later .

Probably above your pay grade. You'd need to know the basics of the Linux commandline interface, which commands to run, where to look and how to interpret the results.

If the problem of running out of space in the firmware flash happens again, it may be worth trying to chase down, but it would probably need a few iterations of instructions on what to do and reporting back of what you found.

[csutak40]

It worked!!!
The only thing that didn't work was that it didn't ask me if I wanted to restore the backup. I then went to backup to manually restore it, but it says I have to backup to restore. Would it have wiped it, or is there anywhere I could find it?
Hmm. Something weird...
Logged into IceTV and did a fetch. It seems to have worked, in that I now have timers for the week, but it is definitely missing some timers for today (only checked today so far) There should be 6 programs recording and it only has one
Actually looking further.. There are problems with the whole week. Lots of programs missing, OTOH, I have Dr Phil doubled up for tomorrow

[csutak40]

OK. Got a new, annoying problem. I seem to have acquired subtitles. I have tried everything and can't get rid of them! They are multicoloured, quite nice, better than normal subtitles you get with foreign movies, but would prefer them not being there, anyway

[MrQuade]

What happens when you press the Subtitle button to turn them off?

Too simple! How embarrassment!

No, the backups wouldn't have been wiped. There are none present in the default location (/media/hdd/backup/beyonwiz/v1), so none can be restored.
Did you previously change the backup location? When was the last time you recall taking a backup on the T4?

Did you do a 'Resend all recordings for this device' from the IceTV end?
Delete both Dr Phil timers before you resend all.
Set your pre/post padding before you resend all.

[csutak40]

I couldn't remember when I did, so I did one just before I ran the re-flash. It popped up and said it was done, but possibly it didn't do it? I never changed the backup location - wouldn't have a clue how

Thank you! My problem is, I forget how to do things when I haven't done them for a while. Getting senile, I suspect.
That, sort of, worked.
I ended up with some (not sure if all) the missing recordings, however Dr Phil turned up twice again (exactly the same, starting and finishing at the same time, same channel..) There was another doubled up show and some of the ones already there before (with the wrong padding) remained.
So, I just deleted all of the recordings and ran the resend again.
I suspect this goes under "a little knowledge is a dangerous thing", and I shouldn't have done that, because half the recordings have disappeared (including Dr Phil )
I had a look in "My Week" and discovered that all the missing shows had "This show is part of a series recording but will not be recorded. Record this episode."
Clicking on "record this episode" works, but only for that episode, not for the rest of the week (they aren't all missing for the whole week, but most are) I tried "update series recording" but that didn't fix it
I have now gone through the whole week and clicked on "record this episode" for all the ones I could remember, but no doubt I've missed some
What have I done, and how do I fix it?

[Grumpy_Geoff]

I don't know that you can fix it now, except by doing the "Record this episode" action.

If you delete a timer from the Wiz end, that tells the IceTV server you don't want to record that particular episode.
I think the trick is to disable IceTV before deleting a "duplicate" timer, then re-enable IceTV.
The same would go for deleting them all before a resend all timers from IceTV.

I think when I told you to adjust the default padding first before the "resend all" it actually made it worse, as you ended up with more doubled up timers - some with the old padding, some with the new padding.
I was thinking from the perspective of a clean slate, which of course your T4 wasn't in
Perhaps the best option in that scenario was to reflash with 20191106 again, then set up including adjusting the default padding first, and then resend all timers from IceTV. That would have left IceTV with all the episodes intact.

I though the Wiz didn't allow exact timer duplicates, so I'm a bit surprised that you have some for the same start/duration/service.

[Grumpy_Geoff]

I have now gone through the whole week and clicked on "record this episode" for all the ones I could remember, but no doubt I've missed some

In 'Manage Series' you should be able to expand a series that is currently showing on TV and choose 'View Upcoming Episodes' to see if the relevant timers are scheduled, and if not then set them from the web page (or even from the T4's EPG).
