LVMは動的に領域を拡張できて便利なわけですが、ファイルシステムに、 xfsを使用している時の、領域拡張法法を記しておきます。

# lvresize -L +500M /dev/vg01/lv01# xfs_growfs /mnt/lv01-mountpoint xfs_growfsは、マウントポイントをパラメータにとるので注意。

# xfs_growfs --help xfs_growfs: invalid option -- '-' Usage: xfs_growfs [options] mountpoint

Options: -d grow data/metadata section -l grow log section -r grow realtime section -n don't change anything, just show geometry -I allow inode numbers to exceed 32 significant bits -i convert log from external to internal format -t alternate location for mount table (/etc/mtab) -x convert log from internal to external format -D size grow data/metadata section to size blks -L size grow/shrink log section to size blks -R size grow realtime section to size blks -e size set realtime extent size to size blks -m imaxpct set inode max percent to imaxpct -V print version information
