Error: (b30370) Can't sort.

Last Updated: Sep 02, 2014 09:15AM CEST

Symptom:  

The backup fails and in the backup client log you will find
(b30370) Can't sort.
(b9030) Nothing to store.

Explanation: 

Hiback UNIX/Linux clients prepare the backup file set in regular files.
The preparation consists of 3 steps:

creation of the file list
deletion of excludes
sort of the resulting list by node number (system utility sort)

Each of the steps write their results into a separate temporary file in &tmpdir (CONDEV setting). Having a large number of files in the file lists results in an appropriate amount of disc space needed for the temporary files.

Possible causes:

lack of disk space
environmental variable settings influencing the behavior of system utility sort on Solaris
environmental variable settings influencing the behavior of system utility sort on HP-UX

Solution on all OS types:

Provide disk space for the preparation of filesets on the backup client.
If no local disk space is available, change /Hiback/CONDEV setting of &tempdir: to an NFS mounted remote drive, eg.

&tempdir: /mnt/remotemachine/data/temp

Additional solution Solaris:

LC_COLLATE=C
unset LC_CTYPE
It is necessary to have this setting in the calling environment of Hiback (inetd/xinetd).

Additional solution HP-UX:

unset LANG
It is necessary to have this setting in the calling environment of Hiback (inetd/xinetd).
