Raspberry Pi Forums

I have been using the RPi B+ as a torrent box for a couple of weeks without any glitch. I used transmission to download torrents and saved on a pen drive, I used remote client to add new torrents, etc. After a while I couldn't access the Pi. Couldn't login through ssh or use the client. But the power, activity, network LED's seems to be working fine. Then when I plugged it into the TV I saw that a particular error keeps on being repeated and the boot up seems to be in a infinite loop without going to the command line. The error is something like,

EXT4-fs error (device nmbclkop2): ext4_ext_check_inode:481:(something) pblk 0 bad header/extent: too large eh_max - magic f30a, entries 16385, max (SOMETHING)

Can someone say what the trouble is?
Can I recover without having to reinstall everything on SD card ?
If yes, please help recover from it. I don't want to reinstall from scrap once again.

The file system of the (Raspbian?) root partition has errors and they should to be repaired.

The easiest way to repair that partition would be to use a PC (with card reader) running Linux. You do not need to install Linux on your PC. You can run Linux from a LiveCD. You can use Ubuntu, Linux Mint or any other distro:

Boot up your PC from the LiveCD, open a terminal and type this command: You have to identify the device where your SD card has been mapped. I will suppose it will be /dev/sdb. Change to /dev/sdc, /dev/sdd, etc if necessary.

According to the error message (mmcblk0p2), the root partition should be /dev/sdb2. If the automount feature of Linux opened some windows showing the files of the partitions on your SD card, close those windows. Finally type these commands: Switch off your PC and check if you RPi runs properly after this repair process.
