现象: Ctrl+Alt+M / 多显示器菜单切换无效, 选择新布局模式后屏闪并且仍然只使用一块显示器.

修复方式: 客户机打开服务: 停止 vm3dservice (VMware SVGA Helper Service) 将启动设置改为禁用即可.

VMware workstation pro 17 验证有效.

补充: 全屏模式下 Ctrl+Alt, Alt+Space, N 即可最小化当前正在运行的VM

docker compose 模式部署的 gitea 在某次更新之后开始大量出现如下报错:

错误量非常巨大给syslog打崩了, 日志滚动的时候负载特别高会出现无法连接的问题. 经排查发现是mariadb升级的时候没有自动升级库表结构引起. 在 docker-compose.yml mariadb 中添加 MARIADB_AUTO_UPGRADE=1 环境变量再 docker-compose up -d 即可修复.

sudo podman create network test
sudo podman network ls

报错提示

WARN[0000] Error validating CNI config file /etc/cni/net.d/test.conflist: [plugin bridge does not support config version "1.0.0" plugin portmap does not support config version "1.0.0" plugin firewall does not support config version "1.0.0" plugin tuning does not support config version "1.0.0"]

解决方案

看起来是Ubuntu2204的已知问题, 需要手动安装最新版本的containernetworking-plugins

  1. 打开下载页面, 下载最新的deb包

  2. sudo dpkg -i containernetworking-plugins_1.1.1+ds1-3build1_amd64.deb

#!/bin/bash
kafka-mirror-maker --consumer.config mirrormaker-consumer.config --producer.config mirrormaker-producer.config --include 'topic1|topic2'

mirror-maker虽然不被confluent看重(可能是因为他们有专门的同步工具), 不过还是非常好用的. 在线上实际跑了将近三个月的时间, 其自带的重试功能可以保证同步意外断开之后无人值守地自动恢复.

经过接近7个月的测试, 目前两级存储中共有5.1亿条数据, 总数据量约230GB. SSD中热数据量约为10%

背景: 因为SSD存储太贵, 而且一般只有最近14天的数据需要经常查询, 因此把14天外的数据送到HDD里保存节约成本.

  1. 需要新增存储配置文件 storage.xml 其中 cold_disk 为HDD存储配置, cold_volume为HDD存储策略

  1. 给数据表添加TTL策略, 默认去default, 15天以上的去cold_volume
1
alter table database_name.table_name modify TTL create_time TO VOLUME 'default', create_time + INTERVAL 15 DAY TO VOLUME 'cold_volume'
  1. 刷新TTL策略, 强制冷数据移动
1
alter table database_name.table_name materialize ttl

TrueNAS SCALE 22.04.3 运行一直很稳定, 有一天开始突然报错CRITIAL:

1
Error: (401) Reason: Unauthorized HTTP response headers: < CIMultiDictProxy('Audit-Id': '7b4e8f99-ae3e-415e-b80b-d5ab72dadd85', 'Cache-Control': 'no-cache, private', 'Content-Type': 'application/json', 'Date': 'Sun, 28 May 2023 07:27:45 GMT', 'Content-Length': '129') > HTTP response body: {"kind":"Status","apiVersion":"v1","metadata":{},"status":"Failure","message":"Unauthorized","reason":"Unauthorized","code":401}

当时没太当回事, 以为是官方仓库挂了. 一个多月后再检查还是这样, 进shell看了一下journal发现是x509证书过期了:

1
May 29 03:23:29 truenas k3s[11305]: E0529 03:23:29.178174   11305 authentication.go:63] "Unable to authenticate the request" err="[x509: certificate has expired or is not yet valid: current time 2023-05-29T03:23:29+08:00 is after 2023-04-16T16:35:58Z, verifying certificate SN=..., SKID=, AKID=... failed: x509: certificate has expired or is not yet valid: current time 2023-05-29T03:23:29+08:00 is after 2023-04-16T16:35:58Z]"

shell直接运行k3s kubectl get node也会报错提示 Unauthorized.

解决方法很简单, 重启k3s和docker服务就行 (当然重启主机也可以, 只是会中断当前的读写):

2
systemctl stop k3s docker
systemctl start docker k3s
