Tools Received error as Not enough space left on device
Hi Forum,

We have observed one problem in one of our HP-UX machines which runs a software which connects the radio frequency scan devices and the scanned information is stored in the database through the same software.

This software has thrown an error like "Not enough space left on the device". In my experience, this error occurs when there is not enough space left on the partition where the process is trying to write in to a file. However the person who was in charge that time has rectified this issue without actually clearing any disk partition space.

According to that person, he logged off all the connected users, cleared all the <defunct> processes and also cleared the illegal shared memory segments & data queues observed through the ipcs command.

As per my general observation -

- There is enough disk space in the software partition. But I am not aware of the space available in /var or /tmp partitions.
- There is ample memory available for running the programs.

I would like to ask the forum couple of questions:

1) This error "Not enough space left on the device" - Is it due to disk partition space not sufficient or due to insufficient Kernel memory?
2) In HP-UX machines please help to identify:
a) Real memory - Used & Free
b) Virtual memory - Used & Free

3) I tried top command - but in HP-UX it gives a wierd result like -
Memory: XXXXXX (YYYYY) real, ZZZZZZ (WWWWW) virtual, UUUUU free

What are these memory values represented as mentioned above both in & out of parantheses?

4) I tried Glance command - but I didnt understand what are the values represented against cpu utilization, memory utilization and they kept on changing.

5) I tried swapinfo command (swapinfo -tam) - but I didn't understand what is the reserve memory for? It was shown as (-4096 b) which is negative. Also the memory shown in swapinfo - is it virtual or real memory?

6) I tried kmeminfo - But it didn't work

7) I tried vmstat - but failed to understand the meaning of avm & free - do they represent virtual memory? If so why are the values different from the values seen in top command?

Thanks a lot for reading my post. Appreciate your help and your time.

Regards,
Nishant

I suspect the error message means what it says.

Killing processes can easily clear up disk space, because it may finish deleting any files which were deleted but held open by a program.

pls upload more logs ,
your problem no enough space.pls execute #bdf
maybe you need extend your filesystem

your mean "/dev/vg51wh2p/wh2ppkg-dlx 10240000 5819722 4151916 58% /wh2ppkg/dlx" is the directory where the sofware installed ,but i do not see the directory is going to full. and your CPU/MEM use rate is not high.




your memory ，you can use "#machinfo" to check the MEM size.

use “#glance plus m command ” to check the free memory and used memory
