https://bugzilla.novell.com/show_bug.cgi?id=732239 https://bugzilla.novell.com/show_bug.cgi?id=732239#c0 Summary: bad partition alignment by installer Classification: openSUSE Product: openSUSE 12.1 Version: Final Platform: x86-64 OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Installation AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: novell-web@zmi.at QAContact: jsrain@suse.com Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:8.0) Gecko/20100101 Firefox/8.0 I've let the system suggested values: Device Boot Start End Blocks Id System /dev/sda1 * 2048 321535 159744 83 Linux /dev/sda2 321536 33554431 16616448 8e Linux LVM The 2nd partition starts on 321536 which is not well aligned for any RAID system. Please always start a new partition on a sector which is 512KB aligned, so that it fits every RAID stripe alignment. Therefore, let the partition before be sized to a 512KB-1 sector. Reproducible: Always Steps to Reproduce: 1. let installer make partition with LVM 2. 2nd partition not well aligned 3. Actual Results: Big performance penalty as everything from the 2nd partition is not aligned to a RAID stripe set. Expected Results: Get maximum power by aligning to 512KB sector numbers, please! -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I had a value only divible by 2, but not even 4. You're right, it's aligned by 2048 sectors or 1MB. So it's good, thank you. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
