One troubleshooting-when the disk clearly has space, but it cannot be written in, the disk will be troubleshooting

One week at work today, I finally started to operate and maintain the platform and encountered the first practical error.

Today, I encountered an alarm saying that the disk cannot be written and I checked the disk space.

When df-h is used to find that the disk is not fully written, there is still a lot of space available. Then, I wonder if the disk is faulty or not.

Then I consulted other people and checked the inode Number of the disk through df-I. The result showed that the inode number is in this disk.

Solution:

Detach Disk

Format the disk and add inode

And then remount it back to the original location.

Why can't I write files when the disk is not full? There is not enough space to release ......

It depends on whether the file you copied in exceeds the remaining disk space!

Why is there a lot of space in the mobile hard drive, but the memory is insufficient during download?

Insufficient memory does not mean that your hard disk capacity is insufficient, but that your computer memory usage is too large and there is not enough space.
When downloading too many things, it requires a lot of cache space in the memory. If one download is not too large, just clear the memory and release it. There are a lot of software for memory cleaning and release, which can be downloaded online for any time or after a long period of time, and the computer will be restarted. The memory will be automatically released to avoid the computer's sluggish and slow speed.
