I have download a new bitcoin package from official site. And then I ran it with daemon mode also with default configuration (Default means not bitcoin.conf file was created in ~/.bitcoin/.bitcoin.conf). After ran 2 hours. I got stuck, and the process exit. When I checked my disk with:

df -lh

And then, I got those:

Filesystem      Size  Used Avail Use% Mounted on
/dev/vda1        20G   20G  118M 100% /
devtmpfs        3.9G     0  3.9G   0% /dev
tmpfs           3.9G     0  3.9G   0% /dev/shm
tmpfs           3.9G  233M  3.6G   6% /run
tmpfs           3.9G     0  3.9G   0% /sys/fs/cgroup
/dev/vdb        800G  7.7G  792G   1% /data
tmpfs           783M     0  783M   0% /run/user/1000
tmpfs           783M     0  783M   0% /run/user/1001

And I googled for a while, but could't find a good way to move all sync's data to the /dev/vdb. I understand what my mistake came from, but I just fixed it by move data and then put a new configuration with --data-dir=/dev/vdb. and then keep sync it.

So, How do I reach that?

  • Rather than adding —data-dir to the config file, try starting bitcoind by running bitcoind —data-dir=[your directory] [whatever other commands you want to run].

  • @chytrik Did you mean run the bitcoind with --data-dir like ./bitcoind --data-dir=/data ?

  • Anyway, Thank you so much. And could you also point me how to move the old data to the new place?

    best way on unixoide systems to copy data over different media is rsync in a terminal. I usually go "rsync -rpogDtW <source_dir> <target_dir>". Further details are not bitcoin relevant, and should then be asked in another stackexchange forum.

I have try to ran the bitcoind -data-dir=/data/db -daemon , but it's not write the data to the path where I specify. Actually, The right way to do that with :

bitcoind -datadir=/data/db -daemon

Attention 

   -data-dir --> -datadir
