Command description: Enter createBucket to create a bucket according to the BucketName. Each bucket can be set with a different redundancy policy. The redundancy policy is multi-replica or erasure code. The redundancy level can be determined by adjusting the number of the data block and parity block. 3 data blocks and erasure code of 2 parity blocks are used by default, the loss of two blocks is tolerable.
mefs provides dedicated encrypted storage space (LFS) for each user, each storage space contains multiple buckets, buckets are containers that users use to store objects, and each bucket contains multiple objects. We can think of objects as files. The redundancy policy of a bucket can be specified at creation time (all objects stored in the bucket use this redundancy policy).
When creating a bucket policy, the value of dc+pc should be less than the number of providers in the group where the current user belongs. Users can modify the number of dc and pc according to their own needs.
Command description: Enter listBuckets to display all buckets created by this user, including the name of each bucket, creation time, redundancy policy and redundancy parameters (DataCount, ParityCount).
Command description: If BucketName exists, entering headBucket displays its creation time, redundancy policy and redundancy parameters. If BucketName does not exist, it displays that bucket does not exist.

Node home directory:
Using "~/memo_provider" as an example:
Node data storage directory: ~/memo_user_data as an example.
The node home directory is the provider directory and the node storage directory is the provider node data storage directory.
Explanation of parameters:
--password: Enter your provider node password, the default is memoriae.
Init: Execute the initialize command, which will generate your wallet address and generate a configuration file.
Explanation of parameters:
wallet default: Get the default wallet address
Starting node needs both the Memo and cMemo token.
To get the cMemo token, there is one faucet,
This is the MemoChain information.
Memochain information
Chain RPC:
Currency name: CMEMO
Chain ID: 985
Chain browser:
To get Memo Tokens for your wallet, you can transfer some Memo Tokens from other wallet address which has enough Memo Tokens. The provider needs minimum 30 Memo Tokens.
Join our discussing with Slack Link:
Please make sure your user home directory and password are the same as in the previous step.
If there is any deploy issue. Please join the deploy-node discussing with Slack Link:
• When participating as a provider node, you need to execute the declare command (declare the public network address) for communication between nodes;
• Get your public network ip+port ready, I will show you below;
• Note: Execute the command in the container;
• The command mefs-provider info can only be executed after the sync information displays as true. Although the synchronization can be successful without doing so, it will not be able to communicate with other nodes.
Parameter explanation
X.X.X.X is your public ip address.
Port 4007 is your public network port, and the mapped port is the host's port 4001 (-p 4001: the first port 4001 of the boot parameter).
Command description: Enter command net info to view the network id (cid), ip address and port of the current node.
Command description: Enter command net peers to view the network connection information of the current node.
Command description: Enter command net connect to connect to any node; if there is any problem with your node network, please enter command net connect to connect to our public node.
COMMON MISTAKES
ERROR: not have tx fee on chain
Solution: Check the node, both of the cMemo token balance, and the memo balance. The Memo token balance must meet the minimum amount for node startup.
ERROR: execution reversed: can't unpledge during 180d
The node pledge amount needs to be withdrawn 180 days after the last pledge.
