linux服务器重启未自动挂载磁盘解决办法

【1】root用户登录，检查磁盘加载情况
XXXX:~ # df -m
Filesystem                1M-blocks  Used Available Use% Mounted on
devtxx                      32066     1     32066   1% /dev/dev/xx2                    69591 13440     56151  20% /
/dev/dd                      1017   147       871  15% /boot
/dev/xx1                    61410  1518     59893   3% /home
/tmpfs                       6416     0      6416   0% /run/

【2】检查磁盘自动加载情况
XXXX:~ # cat /etc/fstab
UUID=7dddd987-fc61-46ba   swap                 swap       defaults              0 0
/dev/dd/xx_root           /                    xfs        defaults              1 1
UUID=edddd2ba-2a3d-420b-  /boot                xfs        defaults              1 2
/dev/dd/xx_home           /home                xfs        defaults              1 2

【3】查看服务器最近重启记录
XXXX:~ # uptime
 10:28am  up   0:25,  5 users,  load average: 0.00, 0.00, 0.00

【4】查看已安装磁盘,找到未挂载的磁盘目录
XXXX:~ # fdisk -l
Disk /dev/ddd: 150 GiB, 161061273600 bytes, 314572800 sectors
...
Device     Boot    Start       End   Sectors  Size Id Type
/dev/ddd1  *        2048   2105343   2103296    1G 83 Linux
...

Disk /dev/fff: 1000 GiB, 1073741824000 bytes, 2097152000 sectors
...
Device     Boot Start        End    Sectors  Size Id Type
/dev/fff1        2048 2097151999 2097149952 1000G 8e Linux

Disk /dev/sdc: 1000 GiB, 1073741824000 bytes, 2097152000 sectors

/dev/sdc1        2048 2097151999 2097149952 1000G 8e Linux LVM
.........

Disk /dev/mapper/dataddddd: 2 TiB, 2147475259392 bytes, 4194287616 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
【5】加载磁盘到对应目录
XXXX:~ # mount /dev/mapper/dataddddd /data

【6】再次检查磁盘加载情况
XXXX:~ # df -hT
Filesystem                  Type      Size  Used Avail Use% Mounted on
devtmpfs                    devtmpfs   32G  8.0K   32G   1% /dev
。。。
 /dev/mapper/dataddddd xfs       2.0T  1.1T  948G  53% /data

【7】备份磁盘自动装载文件
XXXX:~ # cp /etc/fstab /etc/fstab20230308

【8】在/etc/fstab文件末尾增加 /dev/mapper/dataddddd /data xfs defaults 0 0
