AhsayOBM : 7.5.0.0 to 7.x
OS: Linux
ATTENTION 1st January, 2022: v7 officially End-of-Life [details] ===== 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 |
* | info | ... | ... |
* | 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: Invalid argument
#
===== Resolution =====
To resolve this issue:
- Exclude the affected files/folders from the backup source.
