The disk path displayed in the dashboard is incorrect.


The data disk paths are unified, but one of the TiFlash nodes shows an incorrect path, which seems to display the path with the largest capacity.

Check the names of the physical mount and logical mount, are they backup?

| username: heiwandou | Original post link

No, it isn’t.

Why is the file type NFS? :stuck_out_tongue_winking_eye: :stuck_out_tongue_winking_eye: :stuck_out_tongue_winking_eye:

This is not the path of the cluster nodes; it is the data backup directory of the NFS file sharing system. Otherwise, the disk capacity difference between the two cluster nodes would not be so large.

Sure, please provide the text you need translated.

This is fine, we don’t usually look at this anyway. We have monitoring in place, and as mentioned above, it’s a known issue. There’s one thing I haven’t figured out: when TiFlash is deployed with multiple data directories, how does the dashboard display it? After all, the current frontend only has one bar chart and can only show the capacity of one directory.

Can TiFlash be deployed in multiple directories?

| username: 随缘天空 | Original post link

It should be possible. Isn’t it true that the TiFlash configuration file allows you to specify the configuration information for each node? If you declare it, there will be multiple directories. However, generally, the same component uses the same directory, and it’s rare to differentiate configurations, which doesn’t make much sense.

It should be displayed the same as the mixed deployment. The first record shows one mount point displaying one TiDB, one PD, and one TiKV.

| username: 小龙虾爱大龙虾 | Original post link

Yes, TiFlash supports deployment with multiple data directories. Refer to: 通过 TiUP 部署 TiDB 集群的拓扑文件配置 | PingCAP 文档中心

I haven’t really paid much attention to how it’s displayed here :grinning:

You didn’t mention it, I didn’t notice it either. :+1:

It should be the disk you backed up.
