Device, File System and RAID Types 장치, 파일 시스템과 레이드 유형
{PRODUCT} supports multiple types of devices and file systems. The lists below offer a short description of each available device, file system and RAID type and notes on their usage. {PRODUCT}는 여러 유형의 장치 및 파일 시스템을 지원합니다. 아래 목록은 사용 가능한 각 장치, 파일 시스템과 레이드 유형의 간단한 설명과 사용법에 대한 기록을 제공합니다.
To select a device type or a file system of a partition or a logical volume, select it in the list in xref:Installing_Using_Anaconda.adoc#sect-installation-gui-manual-partitioning[Manual Partitioning] and select a `Device Type` and a `File System` from their respective drop-down menus on the right side of the screen. Then, click `Update Settings` and repeat this process for all mount points you want to modify. 장치 유형 또는 파티션이나 논리 볼륨의 파일 시스템을 선택하려면, xref:Installing_Using_Anaconda.adoc#sect-installation-gui-manual-partitioning[사용자 정의 파티션]의 목록에서 이를 선택하고 화면 오른쪽면에서 해당되는 드롭-다운 메뉴에서 `장치유형`과 `파일 시스템`을 선택합니다.그런 다음에, `설정 최신화`를 눌러주고 수정하려는 모든 적재 지점을 위해 이와 같은 처리를 반복합니다.
To configure software RAID, make sure that you have enough physical hard drives selected as installation targets (the number of separate drives required for each type of RAID is noted in its description). Then, choose a RAID level when creating or modifying a Btrfs volume or LVM volume group, or select `Software RAID` as the device type to create software RAID with standard partitions. For detailed instructions, see xref:Installing_Using_Anaconda.adoc#sect-installation-gui-manual-partitioning-btrfs[Creating a Btrfs Layout], xref:Installing_Using_Anaconda.adoc#sect-installation-gui-manual-partitioning-lvm[Creating a Logical Volume Management (LVM) Layout], and xref:Installing_Using_Anaconda.adoc#sect-installation-gui-manual-partitioning-swraid[Creating Software RAID] as needed. 소프트웨어 레이드를 구성하려면, 설치 대상으로 선택한 물리적 하드 드라이브가 충분한지 확인하세요(각각의 레이드 유형에 필요한 별도의 드라이브 수는이 설명에 기록되어 있습니다). 그런 다음에, Btrfs 볼륨 또는 LVM 볼륨 그룹을 생성 또는 변경 할 때에 레이드 레벨을 선택하거나, 장치 유형으로 '소프트웨어 레이드'를 선택하여 표준 파티션으로 소프트웨어 레이드를 생성합니다. 상세한 지침은, 필요에 따라 xref:Installing_Using_Anaconda.adoc#sect-installation-gui-manual-partitioning-btrfs[Btrfs 레이아웃 생성], xref:Installing_Using_Anaconda.adoc#sect-installation-gui-manual-partitioning-lvm[논리 볼륨 관리(LVM) 레이아웃 생성], 그리고 xref:Installing_Using_Anaconda.adoc#sect-installation-gui-manual-partitioning-swraid[소프트웨어 레이드 생성]을 참조하세요.
Device Types 장치 유형
`Standard Partition` - A standard partition can contain a file system or swap space. Standard partitions are most commonly used for `/boot` and the BIOS Boot and EFI System partitions. LVM logical volumes or Btrfs subvolumes are recommended for most other uses. See xref:appendixes/Disk_Partitions.adoc#appe-disk-partitions-overview[An Introduction to Disk Partitions] for additional information about the concepts behind physical partitions.
`LVM` - Choosing `LVM` as the `Device Type` creates an LVM logical volume and a volume group to contain it (unless one already exists, in which case the new volume is assigned to the existing group). LVM can improve performance when using physical disks and allows you to use multiple disks for a single mount point. For information on how to create a logical volume, see xref:Installing_Using_Anaconda.adoc#sect-installation-gui-manual-partitioning-lvm[Creating a Logical Volume Management (LVM) Layout]. Also see xref:appendixes/Understanding_LVM.adoc#appe-lvm-overview[Understanding LVM] for some additional information about LVM in general.
`LVM Thin Provisioning` - Using thin provisioning, you can manage a storage pool of free space, known as a _thin pool_, which can be allocated to an arbitrary number of devices when needed by applications. The thin pool can be expanded dynamically when needed for cost-effective allocation of storage space.
`RAID` - Creating two or more software RAID partitions allows you to create a software RAID device. One RAID partition is assigned to each disk on the system. See xref:Installing_Using_Anaconda.adoc#sect-installation-gui-manual-partitioning-swraid[Creating Software RAID] for instructions on creating software RAID.
`BTRFS` - Btrfs is a file system with several device-like features. It is capable of addressing and managing more files, larger files, and larger volumes than the ext2, ext3, and ext4 file systems. See xref:Installing_Using_Anaconda.adoc#sect-installation-gui-manual-partitioning-btrfs[Creating a Btrfs Layout] for more information about creating Btrfs volumes.
File Systems 파일 시스템
`ext4` - The ext4 file system is based on the ext3 file system and features a number of improvements. These include support for larger file systems and larger files, faster and more efficient allocation of disk space, no limit on the number of subdirectories within a directory, faster file system checking, and more robust journaling. Ext4 is the default and recommended file system used by {PRODUCT} Workstation and Cloud. The maximum supported size of a single ext4 file system is 50 TB.
`ext3` - The ext3 file system is based on the ext2 file system and has one main advantage - journaling. Using a journaling file system reduces time spent recovering a file system after a crash, as there is no need to check the file system for metadata consistency by running the [command]#fsck# utility every time a crash occurs.
`ext2` - An ext2 file system supports standard Unix file types, including regular files, directories, or symbolic links. It provides the ability to assign long file names, up to 255 characters.
`swap` - Swap partitions are used to support virtual memory. In other words, data is written to a swap partition when there is not enough RAM to store the data your system is processing. A swap partition should always be created; see xref:Installing_Using_Anaconda.adoc#sect-installation-gui-manual-partitioning-recommended[Recommended Partitioning Scheme] for details such as the recommended size.
`xfs` - XFS is a highly scalable, high-performance file system that supports file systems up to 16 exabytes (approximately 16 million terabytes), files up to 8 exabytes (approximately 8 million terabytes), and directory structures containing tens of millions of entries. XFS also supports metadata journaling, which facilitates quicker crash recovery. The maximum supported size of a single XFS file system is 500 TB. Starting with {PRODUCT}{nbsp}22, XFS is the default and recommended file system on {PRODUCT} Server.
Note that the size of an XFS file system cannot currently be reduced without destroying and recreating the file system. If you expect that you will need to adjust the sizes of your file systems often, using XFS is not recommended, as it makes administration substantially more time-consuming.
`vfat` - The VFAT file system is a Linux file system that is compatible with Microsoft Windows long file names on the FAT file system. `vfat` - VFAT 파일 시스템은 FAT 파일 시스템의 Microsoft Windows 긴 파일 이름과 호환되는 리눅스 파일 시스템입니다.
`BIOS Boot` - A very small partition required for booting from a device with a GUID partition table (GPT) on BIOS systems and UEFI systems in BIOS compatibility mode. See xref:Installing_Using_Anaconda.adoc#sect-installation-gui-manual-partitioning-recommended[Recommended Partitioning Scheme] for details.
`EFI System Partition` - A small partition required for booting a device with a GUID partition table (GPT) on a UEFI system. See xref:Installing_Using_Anaconda.adoc#sect-installation-gui-manual-partitioning-recommended[Recommended Partitioning Scheme] for details.
