- Leave 20% free space on trail filesystem.
- Monitor with:
df -h and ggsci> INFO EXTRACT ext01, SHOWCH
Step 3: Use Logdump

- Open Logdump:
GGSCI> LOGDUMP
- Open the file:
LOGDUMP> OPEN /u01/gg/dirdat/rt000123
- Check the file header:
LOGDUMP> FILEHEADER
If the file is empty or corrupt, Logdump will likely report that the file header is missing or invalid. ogg-01184 expected 4 bytes but got 0 bytes in trail
