[Linux] LVM挂载的硬盘重启就掉的问题解决
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

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/datashutdown -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% /bootvgdisplay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/lvDataVG Name vgDataLV UUID xxx...LV Write Access read/writeLV Creation host, time testServer, 2024-08-08 18:30:51 +0800LV Status NOT availableLV Size 2.73 TiBCurrent LE 715400Segments 2Allocation inheritRead ahead sectors auto恢复方法：激活VG
testServer:~ # vgchange -a y vgData1 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
