PRIMECLUSTER Global File Services Configuration and Administration Guide 4.6

C.2 Collecting information for troubleshooting

Collect following material for investigation using super user access privileges when you request troubleshooting to field engineers and if your manual instructs you to do so.

1. Material collected by FJQSS, fjsnap, or pclsnap

2. Crash dump file (/var/crash/*/*)

3. Output of the following command: "sfcfsck -N -o nolog device"

   For device, specify a block special file of the file system where the problem occurs.

If the investigation material must urgently be sent, collect the following materials a and b for the initial investigation:

1. Material collected by sfcsnap

2. /var/log/messages*

Note

• The above materials 1, 2, a, and b should be collected from all nodes where the GFS Shared File System is shared.

• The above material 3 should be collected when a file system needs to be recovered.

• These materials should be collected as soon as the symptom occurred. Some material might not be collected after rebooting the system.

• The materials a and b are of initial investigation. Collect materials a and b first, and then make sure to collect materials 1 to 3.

Point

Use FJQSS if you want to collect the above material 1 with other middleware products that support FJQSS.
