iscsid died and kernel module screwed?

Hi there, We hit a iscsid die case. use ps -ef|grep iscsid, we only saw one iscsid process. Unfortunately, we didn't enable debug log so there are not many logs available. We looked at the iscsid log it states that it received some kernel reported error. Also, in the kernel log, there is OOP

Re: iscsid died and kernel module screwed?

We use 2.0-870.3. The kernel is Ubuntu 8.04 with kernel 2.6.24-24. We get the open-iscsi modules and tools from open-iscsi.org. Thanks. Kevin On Thu, Oct 1, 2009 at 1:19 PM, Mike Christie micha...@cs.wisc.edu wrote: On 09/30/2009 03:27 PM, Kevin Ye wrote: Sep 29 13:02:25 swe_1_ser_2 kernel

Kernel Oops

Hi All, We hit the kernel oops again on our setup. Any suggestion to fix that? Thanks. Our set up is: kernel: 2.6.24-24 open-iscsi: 2.0-870.3 kernel logs: Oct 9 21:15:50 ian_ser_2 kernel: [28466.697051] scsi841 : iSCSI Initiator over TCP/IP Oct 9 21:15:50 ian_ser_2 kernel: [28466.962031] scsi

Re: Kernel Oops

setup, and set this in the iscsid.conf (you could also set it in iscsid.conf then rediscovery the targets so it will get picked up). Kevin On Thu, Oct 15, 2009 at 12:06 PM, Mike Christie micha...@cs.wisc.edu wrote: On 10/14/2009 05:11 PM, Kevin Ye wrote: Hi All, We hit the kernel

Another Kernel Oops?

Hi All, I encountered another kernel oops in the open-iscsi code. Not sure if it is fixed in the new code, but I would like to have some idea about it. Thanks. My setup: Ubuntu 8.04 with kernel 2.6.24-24-generic. Open-iscsi 2.0-870.3 The kernel oops happens after my iscsi target node crashed.

Re: Another Kernel Oops?

Hi Mike, Yes, as I said the target node crashed and then the open-icssi kernel oops happens. So far I only hit it once. I'll try to see if I can reproduce it. Kevin On Wed, Dec 9, 2009 at 8:00 PM, Mike Christie micha...@cs.wisc.edu wrote: Qinghua(Kevin) Ye wrote: Hi All, I encountered
