问题：系统重启后挂在逻辑卷的盘会掉（必现）

环境：SUSE Linux 11 SP4

原因：boot.lvm是关闭的

解决：boot.lvm设置开启

linux centos重启后LV Status NOT available https://www.cnblogs.com/namedgx/p/18022670

详细排查如下，

环境信息：

# cat /etc/SuSE-release
SUSE Linux Enterprise Server 11 (x86_64)
VERSION = 11
PATCHLEVEL = 4

创建好逻辑卷，data路径挂载完，并写入如下行到/etc/fstab

/dev/mapper/vgData-lvData    /opt/data    xfs    defaults    0 0

testServer:~ # df -h
Filesystem                     Size  Used Avail Use% Mounted on
/dev/sda3                      1.2T  2.1G  1.2T   1% /
udev                           127G  448K  127G   1% /dev
tmpfs                          127G  728K  127G   1% /dev/shm
/dev/sda1                     1009M   64M  895M   7% /boot
/dev/mapper/vgData-lvData      2.8T    6G  2.8T   1% /opt/data

shutdown -r now 重启后，data盘掉了，且手动无法挂载

testServer:~ # df -h
Filesystem                     Size  Used Avail Use% Mounted on
/dev/sda3                      1.2T  2.1G  1.2T   1% /
udev                           127G  448K  127G   1% /dev
tmpfs                          127G  728K  127G   1% /dev/shm
/dev/sda1                     1009M   64M  895M   7% /boot

vgdisplay查看VG(没有问题)

lvdisplay查看LV，状态如下

LV Status              NOT available

testServer:~ # lvdisplay
  --- Logical volume ---
  LV Name                /dev/vgData/lvData
  VG Name                vgData
  LV UUID                xxx...
  LV Write Access        read/write
  LV Creation host, time testServer, 2024-08-08 18:30:51 +0800
  LV Status              NOT available
  LV Size                2.73 TiB
  Current LE             715400
  Segments               2
  Allocation             inherit
  Read ahead sectors     auto

恢复方法：激活VG

testServer:~ # vgchange  -a y vgData
  1 logical volume(s) in volume group "vgData" now active
testServer:~ # mount -a
testServer:~ # df -h
Filesystem                     Size  Used Avail Use% Mounted on
……
/dev/mapper/vgData-lvData  2.8T    6G  2.8T   1% /home

但是，这个问题重启必现，网络查看资料，检查boot.lvm，发现其状态是关闭的，而其它正常挂载的服务器，boot.lvm为on

chkconfig -A | grep boot.lvm

testServer:~ # chkconfig -A | grep boot.lvm
boot.lvm                 off
boot.lvm_monitor         on
testServer:~ #

chkconfig boot.lvm on 将其开启，再尝试重启服务器，挂在LVM的盘不会再掉了
