SUSE Linux逻辑卷扩容


在Azure上面工作的一台SUSE日志盘爆满了,我们可以创建一块Azure托管磁盘,附加到虚拟机上以后,给指定逻辑卷扩容:

PSTIPS01:~ # sudo pvcreate /dev/sdg
  Physical volume "/dev/sdg" successfully created

PSTIPS01:~ # sudo vgextend vg_PSTIPS_log /dev/sdg
  Volume group "vg_PSTIPS_log" successfully extended

PSTIPS01:~ # lvextend -L +480G /dev/vg_PSTIPS_log/PSTIPS_log
 Size of logical volume vg_PSTIPS_log/PSTIPS_log changed from 128.00 GiB (32767 extents) to 608.00 GiB (155647 extents).
 Logical volume PSTIPS_log successfully resized

PSTIPS01:~ # xfs_growfs /dev/vg_PSTIPS_log/PSTIPS_log
