[opensuse-autoinstall] start offset on partition table / performance issues on vmware and raid systems
Hi, we are using sles11 in a vmware (esxi) enviornment and on Dell R510 Raid 5 devices. I've read there are performance issues due to a unsatisfying partition layout on the operating system which doesn't fit to the unterlying partition layout from the hardware/disks. Instead of one read request the underlying devices have to make two because the blocks are shifted and are not suit on eachother. i.e. - a report from netapp http://media.netapp.com/documents/tr_3593.pdf Is there any way to insert a start offset in the partition layout in the rules.xml file - or are there any other suggestions regarding this problem?

that's not supported yet but I have a feature request for it. The only idea that comes to my mind is doing the partitioning in a pre-script and let autoyast "reuse" the partitions by "create=false". Not nice maybe but that should work. -- ciao, Uwe Gansert Uwe Gansert SUSE LINUX Products GmbH, GF: Markus Rex, HRB 16746 (AG Nürnberg) Business: http://www.suse.de/~ug -- To unsubscribe, e-mail: opensuse-autoinstall+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-autoinstall+help@opensuse.org
