===== Problem Description: =====
When performing a file backup job with AhsayOBM on a Linux machine the following error is shown in the backup log **Error="[IOException] [NixUtil.c][read] Invalid argument"**:
^No. ^Type ^Timestamp ^Log ^
| * |erro | YYYY/MM/DD hh:mm:ss | [New File] File="/filename01" Error="[IOException] [NixUtil.c][read] Invalid argument" |
| * | erro | YYYY/MM/DD hh:mm:ss | [New File] File="/filename02" Error="[IOException] [NixUtil.c][read] Invalid argument" |
===== Cause: =====
The **"Invalid argument"** error message is returned by the Linux operating system. It is related to the permission setting of the file or folder selected for backup.
__Example:__
The following files in the /selinux folder on CentOS 6 where the root account only has write access permission; **commit_pending_bools, disable, and load**. An "Invalid argument" error will be triggered even when root tries to read the contents of the file at the operating system level.
--w-------. 1 root root 0 Aug 17 15:54 /selinux/commit_pending_bools
--w-------. 1 root root 0 Aug 16 15:47 /selinux/disable
--w-------. 1 root root 0 Aug 16 15:47 /selinux/load
#
# cat /selinux/load
cat: /selinux/load: Invalid argument
===== Resolution: =====
To resolve this issue:
- Exclude the affected files/folders from the backup source.
