Problem Description

The log space in the customer environment is full. It is found that the kernel log or LOG_dmesg.txt is full.

Root cause

Storage anomalies cause IO to get stuck, and the kernel outputs a large number of logs, causing the log space to be full. This happens with a very low probability. Currently, 556R1 also has this problem, and only the 2-in-1 version has been fixed.

solution

Check the kernel log and LOG_dmesg.txt and find that they are all
[sfvtk] put through command 0x log


Solution:
1. Delete oversized logs

2. Contact R&D to find a workaround (it may not be possible, it needs R&D's judgment), upgrade to the two-in-one version, the two-in-one version has solved the root cause
