Odd. The tree builds fine, including the lock file, once the config was good:
/mnt ├── fast │ └── leveldb │ ├── 0 │ │ ├── CURRENT │ │ ├── LOCK │ │ ├── LOG │ │ ├── MANIFEST-000002 │ │ ├── sst_0 │ │ ├── sst_1 │ │ ├── sst_2 │ │ └── sst_3 │ ├── 1096126227998177188652763624537212264741949407232 │ │ ├── CURRENT │ │ ├── LOCK │ │ ├── LOG │ │ ├── MANIFEST-000002 │ │ ├── sst_0 │ │ ├── sst_1 │ │ ├── sst_2 │ │ └── sst_3 ├── slow │ └── leveldb │ ├── 0 │ │ ├── sst_4 │ │ ├── sst_5 │ │ └── sst_6 │ ├── 1096126227998177188652763624537212264741949407232 │ │ ├── sst_4 │ │ ├── sst_5 │ │ └── sst_6 What, if anything is Riak building in your tree? Again, I had to create the leveldb directory in each path manually. Did a chmod a+rwx on directories fast, slow, fast/leveldb, and slow/leveldb. Then started the code and waited. I was getting your LOCK crash before I added the data_root line to the config. Matthew P.S. It may be hours before I respond again.
