After running for a while, the disk usage rate grows as the number of the NMS increases. What can we do to clean up the disk space?
There are 3 ways to clean up disk space:
1. Database backup files. Database backup files are stored in the /opt/n2000/backup directory and named according to the backup date. We can see when they were backed up according to the names. The backup file created long ago can be deleted to release some space.
2. Log storage files. Log storage files are saved in the /opt/n2000/server/dump directory, including user logs of NMS, alarms and events. These files are also named according to their creation date, and can be deleted to release some disk space.
3. Find core files. You can use the coreadm command first to locate the directory. For example:
root@N2000Server # coreadm
global core file pattern: /export/home
init core file pattern: core
global core dumps: enabled
per-process core dumps: enabled
global setid core dumps: enabled
per-process setid core dumps: enabled
global core dump logging: disabled
Then we can go to the /export/home/ directory to see if core files exit. Generally, the size of core files is large. Delete the core files to release some disk space.
It is recommended that the user check the network management system periodically to find out directories that will be full soon. This can ensure the stability of the system.
