Hi all, i am trying to run bitcoin fullnode in RaspberryPi 2 model B. But when I run bitcoind to syncronize blockchain  it fails after 200K downloaded blocks every time. In db.log:

__db_meta_setup: /home/storage/chain/wallet.dat: unexpected file type or format

when I try "getinfo" command, and

Page 0: metadata page corrupted
Page 0: could not check metadata page
wallet.dat: DB_VERIFY_BAD: Database verification failed
__db_meta_setup: /home/storage/chain/wallet.dat: unexpected file type or format

when I try to stop&start daemon
last lines in debug.log is :

Can somebody help me with this problem?

Looks like you have a problem with the wallet file. If you don't have any bitcoin one it yet and haven't given out any addresses from it, then just delete the file and you will get a new wallet. Otherwise, you will need to use the salvagewallet command.

If the issue is indeed in the wallet file and if you are simply running a full node, you can disable wallet support altogether, using the -disablewallet command

silly question if it keeps failing at the same point.... is there enough room? dont forget most images for PI are based on 1 or 2 GB sd cards and partitions need to be changed

where is location of blockchain folder? somewhere on SD card or on some external USB storage/remote location.

I stopped using RPi because of frequent filesystem corruptions and it seems that this is the case. if you are running some applications require lot of writes, I bet that corruption is the issue.

try:

tune2fs -c 3 /dev/mmcblkp** (some number for your card) - triggers FS check after each 3 reboots.

open /etc/default/rcS and add/edit line "FSCKFIX=yes" for auto correction.

but anyway, FS corruption on RPi is not anything new or rare...sadly.
