Hi all,

I've been trying to get iscsi to run on a knoppix installation that was installed to a hard drive (knoppix dvd version 5.1.1). My motivation is to create a cheap iscsi target now that Windows Vista has a built-in iscsi initiator in Administrative Tools.

I'm new to iscsi and I have my hard drive partitioned as one hard drive and then downloaded and installed iscsitarget-0.4.14.tar.gz . After unpacking, I installed it with this command:
make KRSC=/usr/src/linux-2.6.19.1/kernel/
and then the command:
make KRSC=/usr/src/linux-2.6.19.1/kernel/ install

The installation appeared to run correctly, with the exception that the ietd.conf file was not automatically placed in /ect/

I manually copied the file to /etc/ and configured it as such:



# Example iscsi target configuration
#
# Everything until the first target definition belongs
# to the global configuration.
# Right now this is only the user configuration used
# during discovery sessions. "IncomingUser" specifies credentials the
# initiator has to provide - several of these are supported. If mutual
# CHAP shall be employed, "OutgoingUser" specifies the user/pass
# combination the target will provide - only one is supported.
# Leave them alone (keep them commented out) if you don't want to use
# authentication for discovery sessions.

iSNSServer 172.25.5.27
#iSNSAccessControl No

#IncomingUser joe secret
#OutgoingUser jack 12charsecret

# Targets definitions start with "Target" and the target name.
# The target name must be a globally unique name, the iSCSI
# standard defines the "iSCSI Qualified Name" as follows:
#
# iqn.yyyy-mm.<reversed domain name>[:identifier]
#
# "yyyy-mm" is the date at which the domain is valid and the identifier
# is freely selectable. For further details please check the iSCSI spec.

Target iqn.2007-04.com.example:media2.disk1.domainnamecom
# Users, who can access this target. The same rules as for discovery
# users apply here.
# Leave them alone if you don't want to use authentication.
#IncomingUser joe secret
#OutgoingUser jim 12charpasswd
# Logical Unit definition
# You must define one logical unit at least.
# Block devices, regular files, LVM, and RAID can be offered
# to the initiators as a block device.
Lun 0 Path=/mnt/iscsi,Type=fileio
# Alias name for this target
Alias media2
# various iSCSI parameters
# (not all are used right now, see also iSCSI spec for details)
#MaxConnections 1
...

I set the Lun 0 Path to /mnt/iscsi because I manually created a the directory "iscsi" under /mnt/ ...

Next I tried to run /etc/init.d/iscsi-target start , but it seems to have failed:


root@media2:/etc/init.d# /etc/init.d/iscsi-target start
Starting iSCSI enterprise target service: FATAL: Error inserting iscsi_trgt (/lib/modules/2.6.19/kernel/iscsi/iscsi_trgt.ko): Unknown symbol in module, or unknown parameter (see dmesg)
netlink fd
: Connection refused
failed.


dmesg states:



iscsi_trgt: Unknown symbol generic_file_read
iscsi_trgt: Unknown symbol generic_file_write


Is my disk not configured correctly? Do I initially need to have a dedicated ext3 partition available as the block device?
I've read elsewhere that iscsitarget-0.4.14.tar.gz does not work with kernel 2.6.19 here:

does anyone else have success making a knoppix hd install an iscsi target? And if so, can you provide detailed installation/ step by step instructions?

Thanks for any and all help.
