Well, /boot by default, is always a primary partition. CentOS (and RedHat) like to create a logical volume manager (LVM) on a separate primary partition, and typically inside the LVM one can create and modify the rest of the various partitions. You do have the flexibility to create TWO LVM's. You can place one LVM on a primary partition on the SSD, and the other on the hard drive. From within both LVM's you can create your partitions to your heart's content. Or for your SSD configuration, don't bother creating an LVM for that. You can use up to 4 primary partition per storage device (and lots of secondary partitions). So, since you only want to place two partitions total on the SSD, simply create those two primary partitions and utilize them. === Al ________________________________ From: Frank Cox <theatre at melvilletheatre.com> To: centos at centos.org Sent: Tuesday, April 17, 2012 3:40 PM Subject: [CentOS] SSD as system drive - partitioning question I mentioned here the other day that I was planning to set up a Centos 6 system using a SSD for the system drive and a regular hard drive for a data drive. My plan is to have everything that doesn't change (much) on the SSD, such as /boot, /lib, /bin and so on. I want to put /tmp and /var and /home on the regular hard drive. Now that I'm at the stage of actually setting this up I have discovered that I don't understand enough about drive partitioning to make this work the way that I want it to. Perhaps I'm missing something obvious. I could create separate partitions on the SSD for /lib, /bin and everything else that I want to put there, then put / on the hard drive, but I would really prefer to put /boot and one other partition on the SSD, and one partition on the hard drive. How can I tell the system that I want /bin and friends on the SSD and /home and /var on the hard drive, but still have just one partition on each drive (plus /boot on the SSD)? If I create / on the hard drive and /ssd on the SSD, then putting bin on the SSD would make it /ssd/bin and that would obviously not be what I want to see. -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com www.creekfm.com - FIFTY THOUSAND WATTS of POW WOW POWER! _______________________________________________ CentOS mailing list CentOS at centos.org http://lists.centos.org/mailman/listinfo/centos
