윈도우에서 사용하던 HDD 를 추가하여 CentOS에서 사용 할 수 있도록한다.
장치명: /dev/sda
Size: 1TB
1. 기존 disk 확인
[root@test ~]# fdisk -l Disk /dev/nvme0n1: 512.1 GB, 512110190592 bytes, 1000215216 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk label type: dos Disk identifier: 0x000cdcd9 Device Boot Start End Blocks Id System /dev/nvme0n1p1 * 2048 2099199 1048576 83 Linux /dev/nvme0n1p2 2099200 1000214527 499057664 8e Linux LVM Disk /dev/sda: 1000.2 GB, 1000204886016 bytes, 1953525168 sectors <-- 대상 장치 Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk label type: dos Disk identifier: 0x948bc441 Device Boot Start End Blocks Id System /dev/sda1 * 2048 1026047 512000 7 HPFS/NTFS/exFAT /dev/sda2 1026048 1953521663 976247808 7 HPFS/NTFS/exFAT |
2. 기존 파티션 제거 및 새로 생성
[root@test ~]# fdisk /dev/sda The device presents a logical sector size that is smaller than the physical sector size. Aligning to a physical sector (or optimal I/O) size boundary is recommended, or performance may be impacted. Welcome to fdisk (util-linux 2.23.2). Changes will remain in memory only, until you decide to write them. Be careful before using the write command. Command (m for help): d <-- 기존 파티션 제거 Partition number (1,2, default 2): Partition 2 is deleted Command (m for help): d <-- 기존 파티션 제거 Selected partition 1 Partition 1 is deleted Command (m for help): n <-- 파티션 새로 생성(기본: primary, 전체 size) Partition type: p primary (0 primary, 0 extended, 4 free) e extended Select (default p): Using default response p Partition number (1-4, default 1): First sector (2048-1953525167, default 2048): Using default value 2048 Last sector, +sectors or +size{K,M,G} (2048-1953525167, default 1953525167): Using default value 1953525167 Partition 1 of type Linux and of size 931.5 GiB is set Command (m for help): w <-- 작업 저장 The partition table has been altered! Calling ioctl() to re-read partition table. Syncing disks. |
3. filesystem 생성(지정?)
[root@test ~]# mkfs -t xfs /dev/sda1 <-- ntfs 가 있다고 나오지만 mkfs.xfs: /dev/sda1 appears to contain an existing filesystem (ntfs). mkfs.xfs: Use the -f option to force overwrite. [root@test ~]# mkfs.xfs -f /dev/sda1 <-- '-f' 옵션으로 강제한다. meta-data=/dev/sda1 isize=512 agcount=4, agsize=61047598 blks = sectsz=4096 attr=2, projid32bit=1 = crc=1 finobt=0, sparse=0 data = bsize=4096 blocks=244190390, imaxpct=25 = sunit=0 swidth=0 blks naming =version 2 bsize=4096 ascii-ci=0 ftype=1 log =internal log bsize=4096 blocks=119233, version=2 = sectsz=4096 sunit=1 blks, lazy-count=1 realtime =none extsz=4096 blocks=0, rtextents=0 |
4. disk 확인
[root@test /]# fdisk -l Disk /dev/nvme0n1: 512.1 GB, 512110190592 bytes, 1000215216 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk label type: dos Disk identifier: 0x000cdcd9 Device Boot Start End Blocks Id System /dev/nvme0n1p1 * 2048 2099199 1048576 83 Linux /dev/nvme0n1p2 2099200 1000214527 499057664 8e Linux LVM Disk /dev/sda: 1000.2 GB, 1000204886016 bytes, 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk label type: dos Disk identifier: 0x948bc441 Device Boot Start End Blocks Id System /dev/sda1 2048 1953525167 976761560 83 Linux |
5. mount 및 확인
[root@test /]# mount /dev/sda1 /home2 [root@test /]# df -k Filesystem 1K-blocks Used Available Use% Mounted on /dev/mapper/centos_test-root 52403200 1205980 51197220 3% / devtmpfs 16307124 0 16307124 0% /dev tmpfs 16320964 0 16320964 0% /dev/shm tmpfs 16320964 9380 16311584 1% /run tmpfs 16320964 0 16320964 0% /sys/fs/cgroup /dev/nvme0n1p1 1038336 207912 830424 21% /boot /dev/mapper/centos_test-home 429964164 33004 429931160 1% /home tmpfs 3264196 0 3264196 0% /run/user/1000 tmpfs 3264196 0 3264196 0% /run/user/0 /dev/sda1 976284628 33040 976251588 1% /home2 |
6. 서버 시작 시 자동 마운트를 위한 설정
- /etc/fstab 에 추가
