为了使用gluster快照，我试图通过LVM创buildLV，因为需要精简configuration的逻辑卷才能使gluster快照起作用。
创build工作，但设置无法在重新启动。 在这个过程中的某个地方一定有一个错误。 这是我正在做的LV创build：
user@node1:~$ sudo lvs [sudo] password for user: LV VG Attr LSize Pool Origin Data% Move Log Copy% Convert root rabbit-vg -wi-ao--- 8.86g swap_1 rabbit-vg -wi-ao--- 5.86g 显示物理卷：

现在重新启动，然后再次检查：
user@node1:~$ sudo lvscan [sudo] password for user: inactive '/dev/gluster/mythinpool' [19.90 GiB] inherit inactive '/dev/gluster/thinv1' [19.90 GiB] inherit ACTIVE '/dev/rabbit-vg/root' [8.86 GiB] inherit ACTIVE '/dev/rabbit-vg/swap_1' [5.86 GiB] inherit
卷不活动，尝试激活
user@node1:~$ sudo vgchange -ay gluster /usr/sbin/thin_check: execvp failed: No such file or directory Check of thin pool gluster/mythinpool failed (status:2). Manual repair required (thin_dump --repair /dev/mapper/gluster-mythinpool_tmeta)! /usr/sbin/thin_check: execvp failed: No such file or directory 0 logical volume(s) in volume group "gluster" now active
无论我做什么，卷都保持不活动状态，我无法安装它们。
我究竟做错了什么？ 预先感谢您的任何帮助。
