Resizing an iSCSI Target Overview When an iSCSI target needs to be expanded, the process varies depending on the underlying storage technology. This guide covers both LVM2 and ZFS-based targets. text/html 2026-01-17T03:24:54+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.linuxservertech.com/unix/iscsi/iscsi_target?rev=1768620294&do=diff Building an iSCSI Target Set up a couple of volumes to be exported To build an iSCSI target, we need to create some space on the file system which will be exported. This can be a file, which is slow, a device, or a zfs volume. The latter has several advantages in that it is very fast, and can take advantages of zfs by taking snapshots, using checksums to maintain reliability, and using compression. (De)compression will be performed on the iSCSI server itself, so the initiators (clients) will n… text/html 2026-01-17T03:23:17+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.linuxservertech.com/unix/iscsi/iscsi_tricks_and_techniques?rev=1768620197&do=diff iSCSI tricks and techniques Assumptions I'm assuming you have built your iSCSI target device using the LVM method in the document Building iSCSI target device. This means that when you want to create/modify/whatever the targets you export, it is simply a matter of manipulating your LVM on the target and, if applicable, adding/deleting entries in /etc/iet/ietd.conf text/html 2026-01-17T03:22:44+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.linuxservertech.com/unix/iscsi/start?rev=1768620164&do=diff iSCSI Yes, I know other systems use iSCIS, but I put this under Unix because it is the only system I work with when dealing with iSCSI iSCSI is an excellent way of allowing one machine to access a volume over a network.

For more updated information, see Building an iSCSI Target I am moving our iSCSI target over to FreeBSD. Our iSCSI servers are generally used as the “disk drives” for Xen virtual servers. NFS with File Backed Devices (FBD) is really too slow when several virtuals are running at the same time, but iSCSI appears to fix this issue.
