Guest server iscsi to san

Rate this Message:
Hey all,
Running a SLES10SP2 fully patched XEN Host server running XFS for the file system. I install an OES2SP1 guest server creating the following partitions: /, swap, /local. I can successfully connect the oes2sp1 guest server to our SAN via ISCSI. I partition that san space with Partitioner. I partition that space as a primary partition, ext3, and mount it as /local/data. All works well. Here is my problem: the guest server will NOT reboot. It hangs on shutting down with "unmounting file systems" staring back at me. I have perfomed some tests. With the ISCSI connection still connected, un-mount /local/data, then reboot the guest server it works fine. So I must be messing something up with the creation of that partition. I'm not quite getting it. Any help would be greatly appreciated. Thanks Hans _______________________________________________ Novell mailing list Novell@... http://netlab1.usu.edu/mailman/listinfo/novell |

For what is worth, I have the same problem when rebooting mine and it is
not running as a guest. It seems to have something to do with the ISCSI stack and I get the errors on rebooting sometimes even when I shut off the NIC that runs the ISCSI initiator.

Hans,
A couple of thoughts. First, the options to mount should be without spaces, just comma separation. Thus that hotplug option is misplaced. Second, I wonder if there is a sequencing problem at work, in that the network may be down before the dismount is attempted. Careful inspection of /etc/init.d scripts and the screen during shutdown should reveal more. There is a shutdown/dismount bug in SLES10 (and 11) which affects dynamically mounted file systems such as sysfs and others. I don't run with iSCSI myself (funds, box counts, etc) but when I was tinkering with it this winter there was no difficulty shutting down a guest in VMware. XEN may be doing things differently, but the VMware guests were happy (as I dimmly recall). Joe D. -------------- Hans Pfeil wrote: > Thanks Joe for your reply. Here is my fstab file.

Hey Joe, you are correct. After looking at the logger screen while the server was shutting down I noticed the NICs being shutdown. A few seconds later then the file systems try to shutdown. That must be the hold up. The NIC is already down with the ISCSI connection to the san. Then when it's time to shutdown the file system it can't communicate to the partition out on the san becasue it's ISCSI and that NIC is already down. How can I add a delay in shutting down the NICS and where would I do that? Is this even possible?

Hans,
The first place to look is at the /etc/init.d start/stop script dependencies, shown as the comments near the top of each file. See the results of those as the sequence numbers in the rcN.d S and K series symlinks. Use chkconfig to add/subtract scripts, insserv to reorder (even though chkconfig calls insserv under some circumstances). Have a look at halt.local as a possible spot to dismount the iSCSI material, and use network as a Required-Start item. It is too late at night for me to dig deeper while writing this, so the above should be sufficient to dig into the details when you have the chance.

NSS Problem
by Mike Kanfer-3
::
Rate this Message:
I have a Netware 6.5 SP7 HP Proliant ML350 server that has a corrupt NSS pool. I was having memory issues that would consistently bring the machine down so I don't have a current backup. I've already run a pool verify and a pool rebuild to no avail. During pool rebuild I get the error "Can't Continue! Status 20444 ( Beast Tree.c [3403])". Any Ideas?
