Centos 5 supported file systems

When choosing a file system, performance is not the most important point. For example if there is a risk that data can get corrupted, lost or compromised, a fast file system should not be used. Oracle does not support files on file systems that do not have a write-through-cache capability. The file system must acknowledge the write operations. One vendor that supplies a supported network file system is Network Appliance, and they are using a modified NFS protocol. There are security requirements as well.

Data files should be accessible only for the database owner. The database server should be able to control all other file and data access. Journaling is a popular characteristic. A mismatch does not indicate that the built in LIS is out of date. The bit kernel for this series is PAE enabled. This series has a supported bit PAE kernel available. Static IP injection may not work if Network Manager has been configured for a given synthetic network adapter on the virtual machine.

For smooth functioning of static IP injection please make sure that either Network Manager is either turned off completely or has been turned off for a specific network adapter through its ifcfg-ethX file. On Windows Server R2 while using virtual fibre channel devices, make sure that logical unit number 0 LUN 0 has been populated.

If LUN 0 has not been populated, a Linux virtual machine might not be able to mount fibre channel devices natively. For built-in LIS, the "hyperv-daemons" package must be installed for this functionality. If there are open file handles during a live virtual machine backup operation, then in some corner cases, the backed-up VHDs might have to undergo a file system consistency check fsck on restore.

Live backup operations can fail silently if the virtual machine has an attached iSCSI device or direct-attached storage also known as a pass-through disk. Hot-Add support is not enabled by default in this distribution. You may use any other desired name for the file. While the Linux Integration Services download creates this rule on installation, the rule is also removed when LIS is uninstalled, so the rule must be recreated if dynamic memory is needed after uninstallation.

Dynamic memory operations can fail if the guest operating system is running too low on memory. The following are some best practices:. Startup memory and minimal memory should be equal to or greater than the amount of memory that the distribution vendor recommends.

Applications that tend to consume the entire available memory on a system are limited to consuming up to 80 percent of available RAM. It is important to understand how storage technologies are configured and how support for them may have changed between major versions of CentOS.

Any RAID functions provided by the mainboard of your computer, or attached controller cards, need to be configured before you begin the installation process. You can connect and configure external USB storage after installation. Most devices are recognized by the kernel, but some devices may not be recognized.

If it is not a requirement to configure these disks during installation, disconnect them to avoid potential problems. The device must be supported by firmware available on the system, or by a UEFI driver.

These sets are automatically detected during the boot process and their device node paths can change across several booting processes. You can find the file system labels and device UUIDs using the blkid command. Supported installation targets An installation target is a storage device that stores CentOS and boots the system. Fibre Channel Host Bus Adapters and multipath devices. Some can require vendor-provided drivers. Xen block devices on Intel processors in Xen virtual machines.

Installing CentOS as an additional operating system on an existing system. Contact your network administrator if you need assistance with networking requirements.
