Marking triaged/medium; All of Precise, Quantal, and Raring should be
affected (same targetcli version). There *is* a workaround, though, as
described in the iscsi-target thread in the description.

** Changed in: targetcli (Ubuntu)
Importance: Undecided => Medium
** Changed in: targetcli (Ubuntu)
Status: New => Triaged
** Description changed:
Buffered fileio mode is not saved properly by the current targetcli
version which causes the setting to be lost upon reboot.
Please see the relevant iscsi-target list thread for the fix:
http://permalink.gmane.org/gmane.linux.scsi.target.devel/3209
- ProblemType: Bug
- DistroRelease: Ubuntu 12.10
+ WORKAROUND (from the iscsi-target thread above):
+
+ You can manually re-enable FILEIO buffered IO by appending
+ ',fd_buffered_io=1' to each your FILEIO backends like so in
+ your /etc/target/tcm_start.sh:
+
+ tcm_node --establishdev fileio_0/fileio_test0 \
+ fd_dev_name=/usr/src/fileio_test0,fd_dev_size=21474836480,fd_buffered_io=1
+
+ This setting can also be checked via configfs directly:
+
+ # cat /sys/kernel/config/target/core/fileio_0/fileio_test0/info
+ Status: ACTIVATED Max Queue Depth: 32 SectorSize: 512 HwMaxSectors: 1024
+ TCM FILEIO ID: 0 File: /usr/src/fileio_test0 Size:
