# Mining Troubleshooting
|
|
|
|
## Config: Filecoin Proof Parameters directory
|
|
|
|
If you want to put the **Filecoin Proof Parameters** in a different directory,
|
|
use the following environment variable:
|
|
|
|
```sh
|
|
FIL_PROOFS_PARAMETER_CACHE
|
|
```
|
|
|
|
## Error: Can't acquire bellman.lock
|
|
|
|
The **Bellman** lockfile is created to lock a GPU for a process. This bug can
|
|
occur when this file isn't properly cleaned up:
|
|
|
|
```sh
|
|
mining block failed: computing election proof: github.com/filecoin-project/lotus/miner.(*Miner).mineOne
|
|
```
|
|
|
|
This bug occurs when the storage miner can't acquire the `bellman.lock`. To fix
|
|
it you need to stop the `lotus-storage-miner` and remove `/tmp/bellman.lock`.
|
|
|
|
## Error: Failed to get api endpoint
|
|
|
|
```sh
|
|
lotus-storage-miner info
|
|
# WARN main lotus-storage-miner/main.go:73 failed to get api endpoint: (/Users/myrmidon/.lotusstorage) %!w(*errors.errorString=&{API not running (no endpoint)}):
|
|
```
|
|
|
|
If you see this, that means your **Lotus Storage Miner** isn't ready yet. You
|
|
need to finish [syncing the chain](https://docs.lotu.sh/en+join-testnet).
|
|
|
|
## Error: Your computer may not be fast enough
|
|
|
|
```sh
|
|
CAUTION: block production took longer than the block delay. Your computer may not be fast enough to keep up
|
|
```
|
|
|
|
If you see this, that means your computer is too slow and your blocks are not
|
|
included in the chain, and you will not receive any rewards.
|
|
|
|
## Error: No space left on device
|
|
|
|
```sh
|
|
lotus-storage-miner pledge-sector
|
|
# No space left on device (os error 28)
|
|
```
|
|
|
|
If you see this, that means `pledge-sector` wrote too much data to `$TMPDIR`
|
|
which by default is the root partition (This is common for Linux setups).
|
|
Usually your root partition does not get the largest partition of storage so you
|
|
will need to change the environment variable to something else.
|
|
|
|
## Error: GPU unused
|
|
|
|
If you suspect that your GPU is not being used, first make sure it is properly
|
|
configured as described in the [testing configuration page](hardware-mining.md).
|
|
Once you've done that (and set the `BELLMAN_CUSTOM_GPU` as appropriate if
|
|
necessary) you can verify your GPU is being used by running a quick lotus-bench
|
|
benchmark.
|
|
|
|
First, to watch GPU utilization run `nvtop` in one terminal, then in a separate
|
|
terminal, run:
|
|
|
|
```sh
|
|
lotus-bench --sector-size=1024
|
|
```
|
|
|
|
This process uses a fair amount of GPU, and generally takes ~4 minutes to
|
|
complete. If you do not see any activity in nvtop from lotus during the entire
|
|
process, it is likely something is misconfigured with your GPU.
