I download a software in my sun pc. during the process of downloading the error message of "No space left in devices" is shown.

Error Message is as follows:
/CADTools/File_to_be_Downloaded1/: truncate: No spcae left on device
/CADTools/File_to_be_Downloaded2/: truncate: No spcae left on device
/CADTools/File_to_be_Downloaded3/: truncate: No spcae left on device

Used Space Info is as follows:

I made the CADTools in /. I am always confused to the space partition.
Can someone give me some advices? Thank you.

"df -k" will tell you which disk is full.
The command you run is only checking the number of files allowed per file-system, but you are hitting the more common disk data size capacity limit.

The info after entering df -k

Because I download a cadence CAD software which seems to be very large,
I made CADtools directory under /exprt/home, then the cadence software soon fill out my sun pc disk space. If I delete the CADTools, then

does it mean the cadence software can not be downloaded into my sun blade 2500? Are there some vitual disk methods to solve the space shortage problem?

can someone give me some advices?

More than 7 gigabytes is indeed pretty large.
Perhaps nfs mounting an external filesystem would help.

I made a directory in /export/home, but the process of downloading cadence is too early to fill out the mounted /export/home filesystems. How to solve this problem?

It would help if you tell:
- what process do you use to download the product.
- If it is splitted in several files or just one big archive
- how big is the whole thing
- why is it so big
- what relationship exists between the directory in /export/home, NFS and the download ...

(1) I use scp command to download the cadence product as follows:

scp -r Remote_server:cad_media /export/home/Cadtools

(2) The Cad is spilitted into 4 parts

(3) I dont know how to see the size of one file by MB format. Please teach me the method.

On Remote_server, run:
That will give you the size in kilobytes.

Why do you want to copy the whole thing while you probably can mount that directory with NFS ?
e.g.:

Your code is very useful to me. I have learned the method to check the size of a file and to check the mounted filesystems.
But after entering the command of remote mount, the RPC time out error message is displayed. I wonder if it is related with the
my user permission.

Cool, how big is what you want to transfer or remotely use ?
Is the filesystem containing cad_media shared ?
RPC time-out is unlikely to be related to permissions. Can you copy/paste the exact command you try and the error message you have in reply ?

The size of cadence media is 1.8GB. And the cadence media directory is not shared mount. The output from the showmount -e is as follows:

/t1home01 192.168.0.11/25 @192.168.0.12/26
/t1home02 192.168.0.11/25 @192.168.0.12/26

I mount the t1home01 as folllows:

mount Remote_host:/Cad_media /export/home/cadtools

- Did you fixed the /export/home disk full issue ?
- The command you shows doesn't mount /t1home01 but /Cad_media, which is not exported and so unmountable ...
- what is your IP address ?

Yes, The /Cad_media is unmountable. I have fixed the space full issue. I am very foolish to download the whole thing of Cad_media.
Actually, we just need very small part of this Cad_media whose size is 1.8GB. I use scp command to download the cad_media. i appreciate your help very much.
By the way I am a VLSI designer and recently I become interested in Solaris and any other Unix OS's. Can you recommand me some advices, powerful books or inernet IP address. Thank you.
