-blocksdir not working with 0.17 #14351

I was trying to test the new blocksdir option from #12653 but could not get it to work regardless of whether I set it in the config file or passed -blocksdir as an argument. blocksdir shows up in bitcoind --help so it should be working, but every time I tried the opening log output would show LevelDB loading from the default ~/.bitcoin/blocks dir where there were no blocks, and then error out immediately.

I'm using a symlinked directory currently instead and that works, fwiw.

This is on Ubuntu 18.04, compiled from 0.17.0-rc4 on an Odroid-HC2 32 bit arm device. The setup I'm using has the main .bitcoin datadir on an SSD and the blocks directory on an HDD.

The .dat files should be in blocksdir, but the index is still in ~/.bitcoin/blocks/index.

Oh thank you very much. I was not aware, I will give that a shot.

That did indeed work. For the record the resulting structure is:

<datadir>/blocks/index <-- Where all .ldb files go <blocksdir>/blocks <-- Where all blk*.dat files go

I'll see if I can help document this more clearly.
