我在这个节点也也有个机器，但是我发现这个节点上的机器好奇怪，CPU使用率经常会卡到100%，然后马上又降下来，查看进程好像也没发现什么异常或攻击行为。我没装MySQL数据库，也把SSH端口换了。但是负载经常就是繁忙状态。
今天看到HostHatch发邮件了，说NVMe VM有严重降低磁盘性能的情况，需要10月3号迁移数据，我一开始还想着是不是因为系统问题，本来还打算今天试试要不要DD个其他系统来着，看来还是等等再说吧。
也不知道迁移的节点是不是还是用NVMe，希望更换服务器以后负载问题能够解决，而且不要降低磁盘速度。。
以下是HostHatch的邮件：
Hello!
You are receiving this email because you currently have an active NVMe VM with us in Chicago on a node with severely decreased disk performance.
Starting on Thursday, 3rd October - we will start migrating all VMs on this node to our other nodes in Chicago. On average, it takes about 4 minutes of downtime and a reboot to migrate a VM with a disk size of 20 GB. It may take more or less time depending on your disk size.
These migrations will start on Thursday (GMT-5 Chicago time) and continue till the end of day. Due to the total number of VMs involved, we are unable to give you an exact timeframe of when your VM may be migrated during these 24 hours, but if you would like, you can open a ticket and schedule the migration at a time window of your choosing.
We understand that this is an inconvenient process and we only migrate a whole node if we feel it is absolutely necessary. We do apologize for the inconvenience being caused to you.
Please do not hesitate to get in touch if we can of any assistance. We very much appreciate your understanding.
Kindest Regards,
Your HostHatch team |
