[HELP] Application data - Not available in mass storage mode

1 Attachment(s)

I have a stange problem with my N9.
I can't install any apps, it says that there is no space left. (The device somehow thinks that it's in mass storage mode :confused: )

Even after flashing, after some time, I always get this error, even if it's not within mass storage mode!?

Does anybody know what the problem might be?

Re: [HELP] Application data - Not available in mass storage mode

When this happens, have you tried connecting it to a computer in mass storage mode, and then disconnecting and checking if it can get out of export mode?

What does it say about mmcblk0p1 when you check the mountpointts or fo a "df -h" ?

You are reading it wrong :p

Its /home/user/MyDocs the mount-point for /dev/mmcblk0p1 then the next line is aegifs mounts...

Okay, now I see what's your problem :)

First I thought it's MyDocs (mmcblk0p1) but it is in fact your /home (mmcblk0p3)

If you look at the "df -h" of your device, you see that you only have /root and /Mydocs mounted, but your /home is on your rootfs :)

Re: [HELP] Application data - Not available in mass storage mode

juiceme,

How do you know his /home is mounted on rootfs? Due to the aegisfs mounts being on /home/user/?

Aegisfs even with mount points on /home/user/ always are on rootfs so that's perfectly normal... Here is a regular user's aegisfs mounts with everything else mounted correctly too...

Hmmm, thats weird. I couldnt mount it, asks me if I'm root or not :/
tried it with opensh, gives an error aswell:

If you look at the first "df -h" listing HtheB provided, there is no "/dev/mmcblk0p3" at all seen there... hence it's not mounted.
Instead, the stuff in /home/ is just under the home folder on rootfs.

tried it with opensh, gives an error aswell:

You cannot mount it because you are runnig the system, you cannot overlay a mount when you have LOTS of open files there currently :D

How to check i now; Create another directory where you can do the mount, or if for example your /mnt/ is unmounted, do:

Code:

mount -t ext4 /dev/mmcblk0p3 /mnt/

Then just check what you have on the /mnt/

When you can check that you actually HAVE the stuff that's supposed to be there, you can boot your device in maintanance mode, copy the recent stuff that you have in your rootFS /home/ to mmcblk0p3, delete all stuff under your rootFS /home/ to save rootfs space, and finally correct the thing why it does not mount it in boot phase.

I suspect you have played with your /sbin/preinit and changed the mount order... :D

Well, I haven't played with anything at all... I don't even have openmode (only inception). I can clearly see whats in /home though... But the problem is that I sometimes I can't install something because the app.data has no space (because somehow, the phone thinks it's is mass storage)

I can't even mount it anywhere else either... Yes, not even on /mnt
It gives the same error as before:

I do not know that much about inception since I dont use that, only open mode.
Is it possible that you need to try mounting under opensh (or adrianesh, or whatever it's called...?)

Also it's possible that your partition table is corrupted or your mmcblk0p3 is shomehow corrupted as being unmountable.

What does it say when you use fdisk to look at the partition table?
Mine looks like this;

Code:

~ # 

~ # /sbin/sfdisk -l

When you reflashed you should have used --no-preserve for the emmc flash to clear up the partitions properly...

Now I think you can just use telnet and export your partitions and re-create everything properly and try instead of doing a reflash...

Re: [HELP] Application data - Not available in mass storage mode

Your partition setup at least looks normal at the first glance.
Propably wisest is to do as thedead1440 suggested; boot in maintanance mode, and check if you can export and/or mount the partition. If not, then there is definitely something wrong there so reformat the partition and cpy the stuff from your rootFS /home there.

BTW, let me guess a thing :D
You might not have realised at the time this went wrong the first time, but I will tell you the symptoms you had at that time:

Your device took a longer than usual to boot up
When it finally booted, it looked like a fresh device; if you had folders on the homescreen now thy were gone and all icons were on one page. If you had a lot of SMS'es or messages all were gone.
However, your MyDocs was intact, all your music/pictures/etc were just as usual.

The cause of this was, obviously the fact that when the device cannot mount your mmcblk0p3 as /home/, it will do a fallback procedure where it sets up your home directory from /etc/skel and the new /home/hierarchy lives now on your mmcblk02p :D

----- edit -----

What I meant to add, the script responsible for the above stuff is "/etc/init/mount-home.conf"

And you could try to run /sbin/fsck.ext4 for your mmcblk0p3, just in case ith hepls :)

Re: [HELP] Application data - Not available in mass storage mode

Everything said already ;)
I had similar experiences during my ubiboot preparation. Repartitioned and everything looked good, but forgot to mkfs anew. Then had wrong size of p1 partition.
After zeroing the first 512 bytes of p1 I had totally starnge mounts!
After mkfs everything was okay.

So if you repartitioned manually and flashed without --no-preserve then you should really follow thedead/juiceme's advice.

Re: [HELP] Application data - Not available in mass storage mode

Well... Actually,

What I did is:

flasher -f -F main.bin --erase-user-data=secure -R

Isn't that enough to also repair the partitions?

Yikes you didn't do it right no wonder... What you have done is just do a rootfs flash not emmc flash... If you screwed up partitions you should have done:

Code:

flasher -f -F main.bin -F emmc.bin --no-preserve --erase-user-data=secure -R

In simple terms, rootfs only flashes your / partition while emmc fixes your partitions ;)

Why is there no emmc for N950? Extract the emmc from the pr1.2 beta one-click flasher and use it ;)

Re: [HELP] Application data - Not available in mass storage mode

I also encountered a device with exactly the same symptoms.

I did the following:

1. dump the partition to a file:

Code:

dd if=/dev/mmcblk0p3 of=/home/user/MyDocs/home.img

2. copy the partition dump to a desktop Linux system
3. run fsck.ext4 on the partition dump

Code:

fsck.ext4 -y home.img

4. copy the fixed partition dump back to the device
5. write the partition dump back to the mmc

Code:

dd of=/dev/mmcblk0p3 if=/home/user/MyDocs/home.img

6. reboot
7. keep fingers crossed that this doesn't happen again :(

I first tried running fsck.ext4 on the device itself but it kept segfaulting. There could be something wrong with the memory chips on the device.

Unfortunately it seems that even though the partition now works again, too many files were corrupted on the partition. Most likely the tracker database was lost since all contacts, messages etc. were lost. However, at least after this /home is on its own partition as expected. Of course that would also be achievable by just making a new ext4 filesystem on the partition and copying the relevant files over from /home/user.
