How to increase /tmp for a resource-intensive program?

[Mateo1041]

I'm running Hugin and it uses /tmp for file processing. I've been getting the following error:

enblend: No space left on device

enblend: an exception occured
enblend: enblend: error writing to image swap file.
Most likely cause: No space for temporary files.
Make sure that there is enough space in the temporary directory

That'd make sense if /tmp is too small as farther up in the log it generates temp files to that location. Here's the config:

So basically my question is, is there a best way in Mageia to increase /tmp folder size? I was thinking 4GB or 6GB since it error out about halfway through currently. I have 4GB of RAM right now I think.

I saw some things when searching Google that I should add the following line to /etc/fstab:

none /tmp tmpfs size=2G 0 0 # Change the size= parameter to whatever you want

There's also the disk partition panel where I can change swap size if that has anything to do with it. But I'm leary when it warns me to back up my data first.

Just wondering if there's a best way to proceed. Thanks for any help you can offer!

Not sure if there's still an answer here that could help others in similar situations, but I did find that Hugin has a preference setting where one can specify a custom temporary file directory instead, so I ended up just doing that instead. Problem solved for me with this software at least.

tmpfs 2.0G 284K 2.0G 1% /tmp

/tmp is by default a tmpfs, that means it is located in RAM, and it will use half your RAM size by default as size. So if you want to increase it, you can change that setting, although you should be aware about the consequence - if more space in /tmp is used, you will have less RAM for applications.

There's also the disk partition panel where I can change swap size if that has anything to do with it. But I'm leary when it warns me to back up my data first.

swap is what's used when your RAM is full, and unused memory pages will be swapped out there, which makes the system slower. You can increase that. The hint about backup always shows up when you open the partitioner, as kind of a safety measure. But increasing swap won't help you in your case.

What you did was probably the best workaround.
