mount: you must specify the filesystem type

1，運行lvcreate -n LVapp  -L 150G VolGroup00; nohup mkfs.ext4 /dev/VolGroup00/LVapp –F &後；

2，執行 mkdir /app; mount  /dev/VolGroup00/LVapp /app 時報錯“mount: you must specify the filesystem type”

3，檢查LVS的狀態

#lvs

 LV                          VG         Attr             LSize   Pool Origin Data%  Meta%  Move Log Cpy%Sync Convert
  LVapp VolGroup00 -wi-a----- 150.00g                                                   
  LVhome   VolGroup00 -wi-ao---- 500.00m                                                   
  LVroot   VolGroup00 -wi-ao----  16.60g 

#lvscan
  ACTIVE            '/dev/VolGroup00/LVroot' [16.60 GiB] inherit
  ACTIVE            '/dev/VolGroup00/LVvar' [29.30 GiB] inherit
  ACTIVE            '/dev/VolGroup00/LVtmp' [39.06 GiB] inherit
  ACTIVE            '/dev/VolGroup00/LVhome' [500.00 MiB] inherit
  ACTIVE            '/dev/VolGroup00/LVswap1' [3.42 GiB] inherit
  ACTIVE            '/dev/VolGroup00/LVapp' [150.00 GiB] inherit 

 

4,估計是nohup mkfs.ext4 /dev/VolGroup00/LVapp –F &腳本執行結果有問題
