3.2.1.1.4 Check If Directory Supports Large File Systems
Use the fsadm command as root to check if your directory supports large file systems. If you do
not execute this command as root, you may not retrieve meaningful results. Following is an
example:
<root>$ /usr/sbin/fsadm <mount_point>
Following is example output when the file system is set up to support large files and when it is
not set up to support large files:
<root>$ /usr/sbin/fsadm /extra
fsadm: /etc/default/fs is used for determining the file system type
largefiles
<root>$ /usr/sbin/fsadm /stand
fsadm: /etc/default/fs is used for determining the file system type
nolargefiles
You can use the /usr/sbin/fsadm command to set the directory to support large files. For
example, to convert a hfs file system from nolargefiles to largefiles, issue the following command:
$ fsadm -f hfs -o largefiles /dev/vg02/lvol1
Alternatively, if the directory does not support large file systems, you can write the core file to
a different directory. Do this by setting the JAVA_CORE_DESTINATION environment variable
(available starting with SDK 1.4.2) to the name of the directory and create the directory. For
example:
$ export JAVA_CORE_DESTINATION=<alt_dir>
$ mkdir $JAVA_CORE_DESTINATION
Java creates a directory named core under the JAVA_CORE_DESTINATION directory where the
core and hs_err_pid<pid>.log files are written. For example:
$ cd $JAVA_CORE_DESTINATION
$ ls
core.29757
$ ll core.29757
