1.186.1. RHBA-2010:0067: bug fix and enhancement update


This update has already been released (prior to the GA of this release) as errata RHBA-2010:0067
An updated scsi-target-utils package that fixes various bugs is now available.
The scsi-target-utils package contains the daemon and tools to set up and monitor SCSI targets. Currently, iSCSI software and iSER targets are supported.
This updated scsi-target-utils package includes fixes for the following bugs:
* the tgtadm utility is used to monitor and modify SCSI target software. When using tgtadm to present an LVM-backed target to clients, attempting to create a new file system by running the mkfs utility on a logical volume caused the tgtd daemon to become unresponsive and connection errors to be logged to /var/log/messages. With this update, clients are once again able to successfully create a new file system on an LVM logical volume. (BZ#545785)
* running the command "tgtadm --mode connection --op delete" to instruct tgtadm to close and remove an open connection to a target which has ongoing I/O caused the tgtadm utility to segmentation fault. Subsequently, attempting to stop the tgtd daemon by running "service tgtd stop" failed and resulted in error messages. With this update, it is now possible to use tgtadm to close and remove an open connection to a target which is undergoing I/O without causing tgtadm to crash, and subsequently stopping or restarting the tgtd service proceeds as expected. (BZ#545786)
* attempting to create 32 or more iSCSI targets using tgtadm caused the utility to segmentation fault after successfully creating the first 31 targets. This update fixes this limitation so that tgtadm does not segmentation fault when creating large numbers of targets, such as 400 or more. (BZ#552928)
* the /etc/tgt/targets.conf file now supports more advanced configuration parameters. Refer to the tgt-admin(8) manual page for further information about valid parameters for the /etc/tgt/targets.conf file.
All users of scsi-target-utils are advised to upgrade to this updated package, which resolves these issues.
