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

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.
