How can I increase size of /tmp directory

smartgupta · #1 (**permalink**) 1 Week Ago

Hi All,

I am working with open solaris and in that I need to install one application which first put it's all files in /tmp directory and then place it in respective directory.but when i am trying to do it,it is giving the following message--

Code:

Abc@opensolaris#. ./xyz.bin
Using /tmp for temporary storage.
bash: fork: Not enough space
bash: [: =: unary operator expected
Unpacking to /tmp/X.tar...
tail: cannot open input
Checksumming...
sum1=0
sumResults1=
sum2=0
sumResults2=
Unable to perform the installation. Either the distribution
file is corrupt or there is insufficient free space in /tmp.
This product requires free space at least 3 times the size
of the distribution file in /tmp. If that much is available,
please try downloading the file again.
Use 'bash <path>' to specify an alternate temporary directory.

So Please tell me how can I increase the size of /tmp directory in openSolaris.

Thanks in advance..

You can delete old unused files in your /tmp directory (disk partition)
You can move old unused files in your /tmp directory (disk partition) to a new directory
You can create a directory in another file system and use a symbolic link to that directory /tmp --> /New_Directory_In_Big_Partition
You can install a cheap, big disk drive and mount it as /tmp

etc.

The previous reply assumes /tmp is a partition which it is almost never the case under Solaris.

/tmp is backed by virtual memory (i.e. RAM + swap) so to increase available space on it, either you reduce your VM usage by stopping processes using it or increase its total size by adding a swap device.

If you have space available on an existing partition, the simplest way is to create a swap file on it (let say you have more than 1gb free on /export):

Code:

mkfile 1g /export/swapfile
swap -a /export/swapfile

If you are using ZFS, the way to add swap space is different than the one I just wrote.

In your case you can specify another alternate directory as your installation program suggests.

And by the way, symlinking /tmp to another directory is probably unsupported and at least requires this directory specific permissions to be preserved.

I tryied it but getting the error--

Quote:

#mkfile 1g /export/swapfile
#swap -a /export/swapfile
/export/swapfile:invalid operation for this filesystem type.

Yes, I already wrote these commands won't work with ZFS.

Code:

rm /export/swapfile
zfs create -V 1gb rpool/extraswap
swap -a /dev/zvol/dsk/rpool/extraswap
