Hello list, I'm just browsing throught the "latest" changes in the Linux I/O Stack. Some changes, while made for 4k drives, would perfectly solve the "block alignment issue" on linux.
The changes mentioned here: https://www.redhat.com/f/pdf/summit/msnitzer_1120_optimize_storage.pdf may also fit well with comstar zvols to match the block size. So I set up snv_134, created zvol and connected with current linux (2.6.32). However it seems comstar is not supporting the required page to get the proper values for physical_block_size and logical_block_size described in the slides. Does Comstar Support this or is it a iSCSI Initiator issue ? stressclient5:~# /usr/bin/sg_inq -p 0xb0 /dev/sda VPD INQUIRY: page=0xb0 inquiry: field in cdb illegal (page not supported) sda = scsi disk.
