I've got a setup with 64 partitions - how do I make it accessible from linux? I only seem to get the first 16 partitions:

Hi Wouldn't that be a limitation of the cciss driver, maybe you need to configure the array? The man page for cciss only shows partitions 0-15....
Hi Malcolm,
yes, that is a possibility, although I didn't think the driver had any influence on partitioning and/or how many partitions. I'll check it out, thanks for suggesting it.
Is this some new application of this drive from a different system, or were you previously able to mount this in Linux?
No, this is completely new, I was just going by GPT allowing up 128 primary partitions.
I seem to remember a raging argument about 16 partitions when everything was switching over to SCSI, but it was years ago.
You're right, there used to be a SCSI limitation of 16 partitions, but I that was back in 2.4 kernels. I'm going to see if the hpsa driver will allow me to allocate more than 16 partitions. (cciss is pretty old).
The fix went into 2.6.26 I think. SUSE employee (at the time) Tejun Heo did the work. http://lwn.net/Articles/288953/ I don't know if that only works for libata, or for all SCSI drives. A separate question is if it works for cciss, but I doubt it. Greg -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
