fdisk格式化硬盘

[root@meta /etc/prometheus]#fdisk /dev/sdb 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. Device does not contain a recognized partition table Building a new DOS disklabel with disk identifier 0x1daa8e3b.

xfs_growfs 和 mkfs.xfs区别

mkfs.xfs格式化没有做lvm的磁盘

xfs_growfs格式化做了lvm的磁盘

[root@meta /etc/prometheus]#mkfs.xfs -f /dev/sdb1 # 不同文件系统使用不同的格式化命令 meta-data=/dev/sdb1 isize=512 agcount=4, agsize=3276736 blks = sectsz=512 attr=2, projid32bit=1 = crc=1 finobt=0, sparse=0 data = bsize=4096 blocks=13106944, imaxpct=25 = sunit=0 swidth=0 blks naming =version 2 bsize=4096 ascii-ci=0 ftype=1 log =internal log bsize=4096 blocks=6399, version=2 = sectsz=512 sunit=0 blks, lazy-count=1 realtime =none extsz=4096 blocks=0, rtextents=0

umount报 target is busy

[root@meta /tmp]#df -h Filesystem Size Used Avail Use% Mounted on devtmpfs 7.8G 0 7.8G 0% /dev tmpfs 7.8G 180K 7.8G 1% /dev/shm tmpfs 7.8G 792M 7.0G 10% /run tmpfs 7.8G 0 7.8G 0% /sys/fs/cgroup /dev/sda1 40G 21G 20G 51% / /dev/sdb1 50G 13G 38G 26% /prometheus tmpfs 1.6G 0 1.6G 0% /run/user/0 [root@meta /tmp]#mount /dev/sdb1 /prometheus

[root@meta /data/prometheus/data]#umount -v /dev/sdb1 umount: /data: target is busy. (In some cases useful info about processes that use the device is found by lsof(8) or fuser(1))

解决

对付系统文件正忙的另一种方法是执行延迟卸载： [root@meta /data/prometheus/data]#umount -vl /data/ umount: /data (/dev/sdb1) unmounted 延迟卸载（lazy unmount）会立即卸载目录树里的文件系统，等到设备不再繁忙时才清理所有相关资源
