文件系統查看
在文件系統創建完成後，在日常的運維工作中，往往需要查看磁盤的分區標簽，在掛載分區時往往需要通過UUID掛載，因為通過設備名穩定性較差，隨著分區的增和刪，分區會發生變化,因此通過UUID和標簽掛載。
1. Findfs查看驗證標簽或UUID 對應分區
命令 | 選項 |
findfs | LABEL=label 查看對應分區 |
UUID=uuid 查看對應分區 | |
[[email protected] ~]#findfs LABEL="firstpart" /dev/sdb1 [[email protected] ~]#findfs UUID="de435737-22bc-4168-999f-d430efce2d09" /dev/sdb1 | |
2. Blkid查看標簽或UUID對應分區及文件系統類型
命令 | 選項 |
blkid | LABEL=label |
UUID=uuid | |
不加選項 | |
[[email protected] ~]#blkid -L firstpart /dev/sdb1 [[email protected] ~]#blkid -U de435737-22bc-4168-999f-d430efce2d09 /dev/sdb1 [[email protected] ~]#blkid #查看對應文件系統 /dev/sr0: UUID="2015-12-09-22-36-30-00" LABEL="CentOS 7 x86_64" TYPE="iso9660" PTTYPE="dos" /dev/sda1: UUID="4b334ea4-8921-499a-88a1-b7d00f3523c1" TYPE="xfs" /dev/sda2: UUID="5ed67ed6-4554-4f0f-aea0-bcf690d19d7c" TYPE="xfs" /dev/sda3: UUID="0b3e907d-455e-4322-90c1-7e6989df43db" TYPE="xfs" /dev/sda5: UUID="345b21b4-a337-4a75-87d1-cf0b9884cae2" TYPE="swap" /dev/sdb1: LABEL="firstpart" UUID="de435737-22bc-4168-999f-d430efce2d09" TYPE="ext4" | |
3. df –T查看文件系統類型
命令 | 選項 | 含義 |
Df | -a | Include dummy file systems |
-B | scale sizes by SIZE before printing them; | |
-h | print sizes in human readable format | |
-i | list inode information instead of block usage | |
-T | print file system type | |
[[email protected] ~]#df –h #顯示查看磁盤大小 Filesystem Size Used Avail Use% Mounted on /dev/sda2 49G 1.6G 48G 4% / devtmpfs 480M 0 480M 0% /dev tmpfs 489M 0 489M 0% /dev/shm tmpfs 489M 6.8M 483M 2% /run tmpfs 489M 0 489M 0% /sys/fs/cgroup /dev/sda3 40G 64M 39G 1% /app /dev/sda1 997M 110M 887M 12% /boot tmpfs 98M 0 98M 0% /run/user/0 /dev/sr0 7.3G 7.3G 0 100% /media [[email protected] ~]#df –T #df查看文件系統 Filesystem Type 1K-blocks Used Available Use% Mounted on /dev/sda2 xfs 51175000 1616456 49558544 4% / devtmpfs devtmpfs 491220 0 491220 0% /dev tmpfs tmpfs 500680 0 500680 0% /dev/shm tmpfs tmpfs 500680 6932 493748 2% /run tmpfs tmpfs 500680 0 500680 0% /sys/fs/cgroup /dev/sda3 xfs 40940000 64652 40875348 1% /app /dev/sda1 xfs 1020588 112304 908284 12% /boot tmpfs tmpfs 100136 0 100136 0% /run/user/0 /dev/sr0 iso9660 7587292 7587292 0 100% /media | ||
4. lsblk 查看文件系統
命令 | 選項 | 含義 |
Lsblk | -d | Include dummy file systems |
-f | scale sizes by SIZE before printing them; | |
-l | print sizes in human readable format | |
[[email protected] ~]#lsblk –f #查看文件系統 NAME FSTYPE LABEL UUID MOUNTPOINT sda ├─sda1 xfs 4b334ea4-8921-499a-88a1-b7d00f3523c1 /boot ├─sda2 xfs 5ed67ed6-4554-4f0f-aea0-bcf690d19d7c / ├─sda3 xfs 0b3e907d-455e-4322-90c1-7e6989df43db /app ├─sda4 └─sda5 swap 345b21b4-a337-4a75-87d1-cf0b9884cae2 [SWAP] sdb └─sdb1 ext4 firstpart de435737-22bc-4168-999f-d430efce2d09 sr0 iso9660 CentOS 7 x86_64 2015-12-09-22-36-30-00 /media | ||
