I'm not sure what 'iscsi loopback' even means. iSCSI is used to mount a virtual block device hosted on another system (initiator mode) or to share a virtual block device (target mode), while loopback is used to mount a local file as a device, such as an .iso image of an optical disc. can you

.. what is? fellow centosians. how to you mount your loopback targets? I'm trying lvm backstore, I was hoping I would do it with uuid, but it's exposed more than once and how would kernel decide which device to use I don't know. thanks

Hi Viraj, Gluster Ver. 3.x supports replication over WAN but currently very limited. I assume it will expand as time moves on. As for ISCSI. I doubt Glusterfs will ever support ISCSI. ISCSI operates at the block level. Gluster only works on the filesystem level. The only way to have iscsi on Gluster would be to export an iscsi target that is a file on gluster. As for snapshot and

Package: xen-utils-3.2-1 Version: 3.2.1-2 Severity: normal When a DomU is defined as using a file: device the loopback driver will be used to make it appear to be a regular block device. The loopback driver will by default only support 8 nodes so this is a limited resource. http://etbe.coker.com.au/2008/10/22/kernel-issues-with-debian-xen-and-centos-kernels/ If there is a problem that prevents

Hi, I''m experiencing some troubles with an application in a VM (domain-1) which needs to connect too itself via the loopback interface. It seems that the connection process hang during the TCP handshake. I have a running web server in this VM which run perfectly. Logged in Domain-1, i''ve tried to reach the webserver with telnet but the same problem happens. Even pinging the

Hi all I want to configure glusterfs to expose iSCSI target. I followed this artical https://pkalever.wordpress.com/2016/06/23/gluster-solution-for-non-shared-persistent-storage-in-docker-container/ but when I install tcmu-runner. It doesn't work. I setup on CentOS7 and installed tcmu-runner by rpm. When I run targetcli, it not show *user:glfs* and *user:gcow* */>* ls o- /

And the sad part is

Hello i''m using Shorewall v2.2.2 on Fedora Core-3. every funtions that i wanted is working well but when i checked my p2p compatiblity on a local machine(local,dmz zones) the loopback translation (tcp/udp) doesn''t work. i used this tool to check. http://midcom-p2p.sourceforge.net/ and the local system is windows based. note that other fuctions on that system is WORKING. below

Feeling once again like an idiot, I come to the list for help... While my carrier (MCI vi PRI, fwiw) was trying to diagnose a problem, they asked me to put my interface in loopback -- and I couldn't figure out what they meant or how to do it. I've plugged a loopback *connector* into my 405p and tested it internally, but they wanted something that, apparently, looped back _their_

Package: xen-utils-common Version: 3.2.0-2 Severity: normal When file: sources are used for Xen block devices the Xen system will use a loopback device for each one. It's quite common for DomUs to be configured with two block devices (one for storage and one for swap) and not uncommon to have a block device for each filesystem (which makes it easier to grow filesystems). Therefore the

Hi, Running: Freebsd 6.0 I am wondering if it is possible to have acces to loopback ip in a jail. I currently have a server running a jail. In the jail, there is a database and a web server. I would like to be able to have the database only bind on a loopback address and not on the jail's ip. Can this be done and how? Thanks -Cyril

Hi, I am new to DTrace. Want to capture (for specific port #s) the loopback interface (lo0) tcp message flow with the complete message body. Is this possible with DTrace? Are any examples available?

xend will not start a domain if one of the block devices is currently mounted elsewhere, but it will not detect if the device is currently attached to a loopback device. I wouldn''t have thought this a problem, provided that the loop device itself wasn''t in use, but it causes all sorts of strange things to happen. My loop device was mounted with the following command
