Sorry for the delay. When I did the last release, I put it out a little
early and then did several refinements and some bug fixes really quickly
after posting it. This is why we went from 865.0 to 865.X so quickly. In
the hope of not creating as much confusion, I am going to do some
release candidates.
This rc actually went through more testing than the 865.0 because of how
the fedora and Red Hat schedules worked out. There are a lot of changes
though, so please if you are using something like xfs + lvm + iscsi on a
32bit box with high mem, please run some tests before trying out the
release. I tested this release on 32 bit boxes with highmen and without
highmen, 64 bit boxes, with xfs, with ext3, with and without software
raid on a hand full of targets including cisco, istor, netapp and
equallogic, IET, istgt, and open solaris. I did not test iscsi tape
since I do not have such a device, and I was not able to hit the xfs +
iscsi problem with the older release (pre 2.0) so me not hitting hit
with this release may not mean much.
Since test1 the major addition is the fix for when records are
overwritten when discovery is performed:
- SendTargets iSCSI Discovery updating existing records:
./iscsiadm -m discovery -t sendtargets -p 192.168.1.1:3260 \
-o update
If there a record for targetX and portalY exists in the DB, and
is returned during discovery, it will be updated with the info
from the iscsi.conf. New portals will be added and stale
portals will not be removed.
- SendTargets iSCSI Discovery deleting existing records:
./iscsiadm -m discovery -t sendtargets -p 192.168.1.1:3260 \
-o delete
If a record for targetX and portalY exists in the DB, but
is not returned during discovery it will be removed from the DB.
No new portals will be added and existing portal records will not
be changed.
Note: If a session is logged into portal we are going to delete
a record for, it will be logged out then the record will be
deleted.
- SendTargets iSCSI Discovery adding new records:
./iscsiadm -m discovery -t sendtargets -p 192.168.1.1:3260 \
-o new
If there targetX and portalY is returned during discovery and does
not have a record, it will be added. Existing records are not
modified.
- SendTargets iSCSI Discovery using multiple ops:
./iscsiadm -m discovery -t sendtargets -p 192.168.1.1:3260 \
-o new -o delete
This command will add new portals and delete records for portals
no longer returned. It will not change the record information for
existing portals.
The default behavior is what we had before where new portals are added,
stale portals are removed and new and existing portals use the values
from the command line and iscsi.conf (equivalent to passing in all three
operation values at the same time).
There have also been checks in iscsiadm added, so that if you try to
modify a record values which is not allowed you will get an error, or if
you try to delete a record iscsiadm will also log out a session using it
for you.

Let me know how it is.
