制作文件系统(也叫格式化)---mkfs.xfs lvm的绝对类路径 挂载使用 mount --- 使用lvm *制作lvm 的时候可以是一整块硬盘也可以是硬盘分好的区并且还是没有用的。必须是没有做文件系统的。 把多个pv放在卷组中 这个过程叫池化 零碎磁盘汇总 相关命令 pvcreate /dev/sdb(*) vgcreate vg_1(卷组名) /dev/sdb(...
现在需要把sdb2分区和sdb1分区合并,以实现对sdb1的扩容,注意,此种情况不要在生产场景操作,仅作为演示用,生产场景一般是事先规划好不会出现扩容需求,非I/O密集应用可以采用LVM实现规范动态扩容。 以下是扩容实战步骤。 1)记录分区的柱面起始信息: [root@cs6 ~]# fdisk -l /dev/sdb Disk/dev/sdb:1073MB,107...

-K Keep, do not attempt to discard blocks at mkfs time (discarding blocks initially is useful on solid state devices and sparse / thin-provisioned storage). 命令示例如下: mkfs.ext4 -K </dev/mapper/path_to_lvm_volume> # For ext4 filesystem mkfs.xfs -K </dev/mapper/path_to_lvm_volume...
English Issue Attempting to create an ext4 filesystem onto an LVM logical volume hangs, with the cpu at 100% and a forced shutdown is necessary. Creating an ext4 filesystem with mkfs onto a partition succeeds, but doing the same operation on an LVM logical volume hangs. ...

LVM filesystem size not matching its logical volume size in RHEL 7.1 We expect that when we create a filesystem with mkfs.xfs its size will match the logical volume size exactly, however we see a difference in RHEL7. We have to use xfs_growfs to match the size.Environment...
