/Var file system in Sun Solaris operating system is primarily used to store the logging information, administrative data, spool directories and temporary files. The size of the files and subdirectories in the /Var file system grows when the tasks like e-mailing, printing and accounting are carried out frequently. An error message might appear when the /Var file system is fully occupied. In such situations, you need to delete the temporary files from /Var file system. Data loss in such situations primarily occurs when you delete any important file or run any interactive UNIX command. Under such situations, you need to restore the data from an updated and valid backup. However, if no backup is available or backup falls short of restoring the required data, then you need to use advanced Sun Solaris Data Recovery tools.

As a practical case, you encounter the below error message when you attempt to save any file on your Solaris based hard drive:

“NOTICE: realloccg /var: file system full.”

After the above error message appears, the operation gets terminated.

Cause:

The root cause for the occurrence of the above error message is occupied /Var file system. Most likely you have /var/logs directory which contains a number of files.

Resolution:

To resolve the above error message, you need to take these steps:

•    Delete core files unless you are going for any debugging.
•    Check the contents of home directory and delete the temporary files from it
•    If /tmp is full and contains large data files, reboot your system to clean the directory

The above error resolving methods are competent enough to solve your problem. But data loss while applying the above resolutions might occur due to deletion of the files. If you are logged into the root directory and deleted some files or run any interactive UNIX command as root, you may face serious problems with your file system, metadata structures and even the operating system as losing your precious data.

However, if the data loss occurs due to any of the above reasons, then you will need to use advanced Sun Solaris Data Recovery tools. Such Sun Solaris Data Recovery utilities incorporate advanced scanning methods to recover your lost files and folders. These utilities are built with highly graphical user interface, which makes them self-explanatory without the need of any technical skills. Such recovery tools recover lost data after fsck is unable to repair the system data structures. These applications also recover lost data post serious corruption scenarios like superblock or inode structure damage.

Stellar Phoenix (Solaris - Intel) Data Recovery is a powerful Sun Solaris Data Recovery tool. The read-only software supports UFS file systems.  It gets installed on Windows (XP, 2003, 2000, NT, ME, 98 and 95) and the affected Sun Solaris hard drive should be connected as slave.
