Re: error when server detect target
looks similar to my Please clarify is this normal when using multipathing? (Buffer I/O error on device sdc, logical block 4) thread... mike gave some good pointers, though i didn't get this resolved for Lenny yet (only for squeeze).

I am not very familiar with Debian. Does Lenny only have the older kernel? If so then I think you do not have many options. 1. You can live with the error messages. They are harmless but anooying. If I remember correctly though it might slow down the startup a bit because we are sending extra IOs, but I cannot remember how bad it was now (I used to work on these boxes when I worked at IBM but that was like 10 years ago). 2. Switch to non rdac mode if you can. That has other drawbacks. 3. I do not know. Post to the dm-devel list and see if other people have suggestions. 4. Ask someone to port the device handler stuff to older kernels. Does debian have that or does Ubuntu do that? I do not know. 5. Switch to RHEL/Centos where we have support :) Just kidding. I work for Red Hat :) -- You received this message because you are subscribed to the Google Groups open-iscsi group. To post to this group, send email to open-is...@googlegroups.com.
