1. 升级步骤说明

​ 若Alaya节点是0.16.1版本，请跳到第3点直接进行更新操作。

$ alaya version
Version: 0.16.1-unstable
Git Commit: 76b3b19b70d6c9a7f0dcc3119471613e3c84dc24

2. 升级注意事项

​ 这是节点从0.16.0升级到0.16.1会出现的注意事项；若是节点没有升级到0.16.1，直接选择从0.16.0升级到0.16.2，也要注意以下事项。

2.1 CPU、内存和磁盘问题

​ 升级过程中部分历史数据会做迁移至Freezer数据库，cpu会有所增加，数据迁移完成恢复正常；升级重启后，少数会有内存增加的情况，数据迁移完成后恢复正常；升级后存储也会有部分提升(例如从30700000块高升级后存储空间将增加约11G）。详细查看Github releases

  • 升级内存

    8G内存的节点在升级重启的过程中小概率会出现内存增加，导致OOM，为了避免这种情况，建议使用swap分区，若有条件也可以选择将机器物理内存升级到16GB。

    增加swap分区

    wget https://download.alaya.network/alaya/scripts/alaya_swap.sh
chmod +x alaya_swap.sh
./alaya_swap.sh

    注意：

    1. 文档提供的alaya_swap.sh 脚本做以下处理：当swap分区不存在，则创建8G的swap分区；当swap分区小于7G，会增加swap分区到8G；当swap分区大于7G，则不创建swap分区。

    2. 若不升级主机内存进行节点升级，出现OOM的情况，导致机器无法连接上；重启主机机器后，可恢复启动进程

  • 扩容磁盘

    升级过程中，磁盘容量有所增加约11G，若磁盘可用容量不足，建议扩容磁盘容量。

2.2 不兼容性问题

​ 本次节点升级后，不能使用0.16.0的版本和升级后的数据进行启动，建议升级前，先下载官方提供的备份数据，存放在节点主机上，若节点升级后不能启动，需要使用0.16.0的版本和数据来启动节点。

  • fast模式备份数据，数据大小是17G的，块高是35716592，当节点启动失败，使用该数据替换data/platon目录

    wget https://download.alaya.network/alaya/nodedata/0.16.0-fast-data.tar.gz
tar -xf 0.16.0-fast-data.tar.gz

3. 更新指南（先更新，暂不重启）

​ 以下步骤以 Ubuntu18.04 系统为例，更新操作分为两种方式：直接使用二进制、源码编译，选其中一种方式更新即可；请严格按照以下步骤操作升级，如有需要帮助请联系客服。

  • 直接用二进制

    # 备份二进制
$ [[ -x /usr/bin/alaya ]] && sudo mv /usr/bin/alaya /usr/bin/alaya_`alaya version | grep '^Version:' | awk -F "[ ,:,-]" '{print $3}'`
# 下载最新的二进制文件
$ wget https://download.alaya.network/alaya/platon/0.16.2/alaya
# 使用新的alaya版本
$ chmod +x alaya
$ sudo mv alaya /usr/bin/alaya
# 查看版本
$ alaya version
Version: 0.16.2-unstable
Git Commit: 430aecb60a61a10613835f4f014f0ecb5a72af5c

  • 源码编译（针对之前已成功编译过的环境，全新编译请参考官网）

    # 备份二进制
$ [[ -x /usr/bin/alaya ]] && sudo mv /usr/bin/alaya /usr/bin/alaya_`alaya version | grep '^Version:' | awk -F "[ ,:,-]" '{print $3}'`
# 编译二进制
$ git clone https://github.com/AlayaNetwork/Alaya-Go.git --recursive
$ cd Alaya-Go 
$ git fetch --all
$ git checkout -b alaya-0.16.2 430aecb60a61a10613835f4f014f0ecb5a72af5c
# 安装依赖和编译，如果出现missing go.sum entry for module，使用go mod tidy移除未使用和添加缺失的依赖
$ go mod download && make all
# 使用新的alaya版本
$ chmod +x build/bin/alaya
$ sudo mv build/bin/alaya /usr/bin/alaya
# 查看版本
$ alaya version
Version: 0.16.2-unstable
Git Commit: 430aecb60a61a10613835f4f014f0ecb5a72af5c

4. 择机重启进程

​ 如果当前节点质押过，首先通过区块链浏览器查看节点是否已经被选为验证人（共识中）
如果已经当选，请等待节点退出验证人（共识中转为活跃中）后再进行重启进程操作。

以下命令仅做参考，根据各自的管理方式，重启alaya进程

nohup alaya --identity alaya-node --datadir ./data --port 16789  --rpcport 6789 --rpcapi "db,platon,net,web3,admin,personal" --rpc --nodekey ./data/nodekey --cbft.blskey ./data/blskey --verbosity 1 --rpcaddr 127.0.0.1 --syncmode "fast" > ./data/platon.log 2>&1 &

5. 版本声明

​ 当版本声明后，可在浏览器查看节点版本

alaya_mtool declare_version --keystore $ALAYA_MTOOLDIR/keystore/staking.json --config $ALAYA_MTOOLDIR/validator/validator_config.json
  • 未质押过的节点，跳过本步骤。
  • 没定义$ALAYA_MTOOLDIR的，需要根据实际部署情况补全绝对路径。

6. 反馈

Version Info

ChainID: 201018

Version: 0.16.2

Git Commit: 430aecb60a61a10613835f4f014f0ecb5a72af5c

Binary Document: https://download.alaya.network/alaya/platon/0.16.2/alaya

1. Upgrade Instructions

  • If you are using the 0.16.1 version, please to Step 3 for the upgrade.
$ alaya version
Version: 0.16.1-unstable
Git Commit: 76b3b19b70d6c9a7f0dcc3119471613e3c84dc24

2. Upgrade Notice

  • The following notices are for the upgrade from 0.16.0 to 0.16.1. However, if you didn’t upgrade to 0.16.1, you could also directly upgrade to 0.16.2. Even so, these reminders would also be helpful.

2.1 About CPU, RAM and Disk

  • During the upgrade, part of the historical data will be migrated to the Freezer database. This will take up more CPU utility, which will return to normal upon completed data migration. When your device is rebooted after the upgrade, in rare cases, you may experience increased RAM use, which will also normalize once the data is migrated. The upgrade will also occupy more storage. For instance, the upgrade at block height 30,700,000 will take up 11GB additional storage space. For more details, please refer to Github releases.

  • RAM upgrade

    During the upgrade and rebooting process, there is a small chance that validators using 8GB RAMs will suffer OOM due to the increased RAM use. To avoid the potential OOM problem, we recommend creating a swap partition or upgrading to 16GB RAM (if possible).

    Add a swap partition

    wget https://download.alaya.network/alaya/scripts/alaya_swap.sh
chmod +x alaya_swap.sh
./alaya_swap.sh

    Notice:

    1. The ‘alaya_swap.sh’ script provided in the document will carry out the following process: Where there is no swap partition, the script will create an 8GB swap partition; where the swap partition is smaller than 7GB, the script will expand it to 8GB; where the swap partition is larger than 7GB, the script will remain inactive.

    2. Validators who carried out the upgrade without expanding their RAM could experience OOM, which will result in connection failures. For such users, the activation process will resume once their device is rebooted.

  • Disk expansion

    The upgrade will take up 11GB additional disk space; where the storage is insufficient, we recommend expanding the disk capacity.

2.2 Incompatibility

  • After the present validator upgrade, you can no longer use the 0.16.0 version and the upgraded data for activation. Validators are advised to download the backup data we provided and have it stored on your validator PC before the upgrade. In case of failed activation after the upgrade, you will need to use the 0.16.0 version and data for activation.

  • The fast model backup data is 17GB big, at the block height of 35,716,592. In case of failed activation, the backup data will be used to replace the data/platon directory.

    wget https://download.alaya.network/alaya/nodedata/0.16.0-fast-data.tar.gz
tar -xf 0.16.0-fast-data.tar.gz

3. Upgrade Instructions (upgrade without rebooting)

  • The following instructions are based on the Ubuntu18.04 system. You could complete the upgrade directly through the binary document or source code compiling. Please carry out the upgrade in strict accordance with the following procedures. If you need any help, feel free to reach out to us through our customer service.

  • Directly activate the binary document

    # Make a binary backup
$ [[ -x /usr/bin/alaya ]] && sudo mv /usr/bin/alaya /usr/bin/alaya_`alaya version | grep '^Version:' | awk -F "[ ,:,-]" '{print $3}'`
# Download the latest binary document
$ wget https://download.alaya.network/alaya/platon/0.16.2/alaya
# Use the latest version of Alaya
$ chmod +x alaya
$ sudo mv alaya /usr/bin/alaya
# Check the version
$ alaya version
Version: 0.16.2-unstable
Git Commit: 430aecb60a61a10613835f4f014f0ecb5a72af5c

  • Source code compiling (The following is intended for previously complied environments. For new compiling, please refer to our official website.)

    # Make a binary backup
$ [[ -x /usr/bin/alaya ]] && sudo mv /usr/bin/alaya /usr/bin/alaya_`alaya version | grep '^Version:' | awk -F "[ ,:,-]" '{print $3}'`
# Compile the binary document
$ git clone https://github.com/AlayaNetwork/Alaya-Go.git --recursive
$ cd Alaya-Go 
$ git fetch --all
$ git checkout -b alaya-0.16.2 430aecb60a61a10613835f4f014f0ecb5a72af5c
# Install the dependency library and compiler. In case of missing go.sum entry for module, please use go mod tidy to remove unused dependencies and add the missing ones.
$ go mod download && make all
# Use the latest version of Alaya
$ chmod +x build/bin/alaya
$ sudo mv build/bin/alaya /usr/bin/alaya
# Check the version
$ alaya version
Version: 0.16.2-unstable
Git Commit: 430aecb60a61a10613835f4f014f0ecb5a72af5c

When to Reboot the Alaya Process

  • If the present node has staked before, please check whether it has been selected as a validator (Verifying) on the Alaya Blockchain Explorer. If so, please reboot the alaya process after the node exits from the validator model (switch from Verifying to Active)

The command below is for reference only. Validators should reboot the alaya process according to their own management approach.

nohup alaya --identity alaya-node --datadir ./data --port 16789  --rpcport 6789 --rpcapi "db,platon,net,web3,admin,personal" --rpc --nodekey ./data/nodekey --cbft.blskey ./data/blskey --verbosity 1 --rpcaddr 127.0.0.1 --syncmode "fast" > ./data/platon.log 2>&1 &

5. Version Statement

  • After the version statement is released, you could check the validator version on the Alaya Blockchain Explorer.
alaya_mtool declare_version --keystore $ALAYA_MTOOLDIR/keystore/staking.json --config $ALAYA_MTOOLDIR/validator/validator_config.json

  • Validators who never staked before could skip this step.

  • Where $ALAYA_MTOOLDIR is not defined, the absolute path should be completed according to the actual deployment.

6. Feedback

  • If your alaya upgrade failed, please provide us feedback in the following channels.
