I/O error when trying access to the XBMC database files

[kraleksandr]

Code:

xbian@xbian ~ $  cp .xbmc/userdata/Database/MyVideos75.db /dev/zero
cp: reading `.xbmc/userdata/Database/MyVideos75.db': Input/output error
cp: failed to extend `/dev/zero': Input/output error

What does it mean? My SDcard becomes broken or what?

First I installed nmap with 69 additional packages, then I tried to remove nmap but apt-get said that 'package list parse error'.
Then I sent 'reboot' to my Pi and after that my media library has gone.
I then remove this packages (nmap+69 additionsl) using dpkg -r but I/O error still appear.

Code:

xbian@xbian ~ $  ls -al .xbmc/userdata/Database/

1/ Check SD card is not full df -h
2/ Try /dev/null instead

[rikardo1979]

I would say that once you have messed up your sys and dont know what happened, than the best,safest and easier way would be to restore your SD card backup

[kraleksandr]

Code:

xbian@xbian ~ $  df -h

Code:

xbian@xbian ~ $  cp .xbmc/userdata/Database/* t/
cp: omitting directory `.xbmc/userdata/Database/CDDB'
cp: reading `.xbmc/userdata/Database/MyVideos75.db': Input/output error
cp: failed to extend `t/MyVideos75.db': Input/output error

Trying fsck.btrfs now...

Is it serious? On second pass same output.

Are you just trying to backup your XBMC settings? Have you tried XBMC backup? Also export library from within XBMC.

cp .xbmc/userdata/Database/* t/ is not a valid command.

I've tried on my machine, mkdir temp, cp .xbmc/userdata/Database/* temp and it works, apart from CDDB which is empty.

Sounds like something is corrupt. Can you access another linux machine and run a check on the card.

No. No. Export - choose folder - Ok -> freeze for few seconds and nothing happens.
fsck log in the previous post.

Also several other files has I/O error.

Can you try:
sudo btrfs fi show
sudo btrfs fi df /

It's not looking good. You have got a backup?

I'm at a loss. I wonder if it got corrupted using the "cp" command on a btrfs file system when rsync should have been used.

It might be possible to recover, but I'm not a btrfs expert. Someone else might be able to help.

Now my Pi didnt boot either. Loading screen and non-blinking ACT led.

Did you try anything prior to this happening?

I think it is time to bite the bullet and do a fresh install.

You may still be able to recover "some" of the files if you have access to another Linux machine but I would put it down to experience and do a fresh install and make sure you have backups.

Only fsck.btrfs and btrfs-restore.

Boot with debug mode ends here:

Code:

mmc0: Controller never released inhibit bit(s).

Definitely went south on you, likely no hope of recovering anything.

Last post of that thread is gsh (Gordon Hollingsworth - Raspberry Pi Developer) asking for a card with this issue to be sent to him if your interested.

[kraleksandr]

After erasing my sdcard (dd from /dev/zero) and installing XBian from b1.1 image it works, but at 3rd reboot that error appears again. Is it trouble with SDcard or with RPi?
