Hi,
With reference to:
File name : /var/lib/one/lib/sh/scripts_common.sh
Function : function tgt_admin_dump_config
Line # : echo "$TGTADMIN --dump |sudo tee $FILE_PATH >/dev/null"
Snippet from the code:
function tgt_admin_dump_config {
FILE_PATH="$1"
echo "$TGTADMIN --dump |sudo tee
$FILE_PATH >/dev/null"
}
Scenario:
1. OpenNebula front-end : CentOS 6.3 server
2. OpenNebula node : Centos 6.3 Server
3. iSCSI Target in : Ubuntu 12.04 server [192.168.1.7]
4. iSCSI Initiator in : OpenNebula Front end (CentOS 6.3
Server)
5. Create a iSCSI datastore in front end with following definition
NAME = production
BASE_IQN="iqn.2012-02.org.opennebula"
DISK_TYPE="block"
DS_MAD="iscsi"
HOST="192.168.1.7"
TM_MAD="iscsi"
VG_NAME="vg-one"
ID NAME CLUSTER IMAGES TYPE TM
0 system - 0 - shared
1 default - 1 fs shared
101 production - 2 iscsi iscsi
6. Creates a new Image (ttylinux.img) with the below template contents in to
the iSCSI datastore
NAME = ttylinuxiscsi-3
PATH = "/var/lib/images/ttylinux.img"
TYPE = OS
Problem definition:
While copying the image to the iSCSI target, error ">/dev/null" failed: sh:
12: Syntax error: Bad fd number" is reported.
Extract from oned.log:

Reason : It happens Ubuntu 12.04 , because , Ubuntu has dash (/bin/sh) and not
bash.
If I change ">& /dev/null" to ">/dev/null 2>&1"" , the
image copies smoothly to the iSCSI target with no FD number error.
Corrected version:
function tgt_admin_dump_config {
FILE_PATH="$1"
echo "$TGTADMIN --dump |sudo tee $FILE_PATH >/dev/null 2>&1"
}
