Info

56 Start-Up If you partition manually, create a swap partition of at least 256 MB. The swap partition is used to free the main memory of data that is not used at the present moment. This keeps the main memory free for the most frequently-used important data. Expert Options Expert opens a menu containing the following commands: Reread Partition Table Rereads the partitioning from disk. For example, you need this after manual partitioning in the text console. Delete Partition Table and Disk Label This completely overwrites the old partition table. For example, this can be helpful if you have problems with unconventional disk labels. Using this method, all data on the hard disk is lost. More Partitioning Tips If the partitioning is performed by YaST and other partitions are detected in the system, these partitions are also entered in the file /etc/fstab to enable easy access to this data. This file contains all partitions in the system with their properties, such as the file system, mount point, and user permissions. Example 2.1 /etc/fstab: Partition Data /dev/sda1 /data1 auto noauto,user 0 0 /dev/sda5 /data2 auto noauto,user 0 0 /dev/sda6 /data3 auto noauto,user 0 0 The partitions, regardless of whether they are Linux or FAT partitions, are specified with the options noauto and user. This allows any user to mount or unmount these partitions as needed. For security reasons, YaST does not automatically enter the exec option here, which is needed for executing programs from the location. However, to run programs from there, you can enter this option manually. This measure is necessary if you encounter system messages such as bad interpreter or Permission denied.
Partitioning and LVM From the expert partitioner, access the LVM configuration with LVM (see Section “LVM Configuration” (Chapter 2, Advanced Disk Setup, ↑Reference)). However, if a working LVM configuration already exists on your system, it is automatically activated as soon as you enter the LVM configuration for the first time in a session. In this case, any disks containing a partition belonging to an activated volume group cannot be repartitioned because the Linux kernel cannot reread the modified partition table of a hard disk when any partition on this disk is in use. However, if you already have a functioning LVM configuration on your system, physical repartitioning should not be necessary. Instead, change the configuration of the logical volumes. At the beginning of the physical volumes (PVs), information about the volume is written to the partition. To reuse such a partition for other non-LVM purposes, it is advisable to delete the beginning of this volume. For example, in the VG system and PV /dev/ sda2, do this with the command dd if=/dev/zero of=/dev/sda2 bs=512 count=1. WARNING: File System for Booting The file system used for booting (the root file system or /boot) must not be stored on an LVM logical volume. Instead, store it on a normal physical partition. 2.5.7 PCI Device Drivers Each kernel driver contains a list of device IDs of all devices it supports. If a new device is not in any driver's database, the device is treated as unsupported, even if it can be used with an existing driver. With this YaST module from System section, you can add PCI IDs. Only advanced users should attempt to use this YaST module. To add an ID, click Add and select how to assign it: by selecting a PCI device from a list or by manually entering PCI values. In the first option, select the PCI device from the provided list then enter the driver or directory name. If the directory is left empty, the driver name is used as the directory name. When assigning PCI ID values manually, enter the appropriate data to set up a PCI ID. Click OK to save your changes. System Configuration with YaST 57
