EXSi里调大硬盘大小后在linux里怎么生效

下面是步骤，强烈建议之前备份数据

1. It looks like you've already rebooted but just in case, ensure the kernel recognizes the larger disk

   echo 1 > /sys/class/scsi_disk/0:0:0:0/device/rescan
   

2. Resize the second partition with fdisk

   fdisk /dev/sda
   p     # print current
   d     # delete
   - 2
   n     # create
   - p   # primary partition
   2     # partition number
   - default first/last cylinders
   t     # change partition id
   - 2
   - 8e (hex code)
   p     # print the current again to verify it's expanded
   w     # write changes
   

3. Reboot the virtual machine

   shutdown -r now
   

4. Once it's back up, resize the LVM physical volume

   pvresize /dev/sda2
   

5. Now resize the LVM logical volume (NOTE: I'm unable to decipher what your logical volumes name is based on the screenshots and thus am assuming LogVol00. You can determine this by running lvdisplay.)

   lvresize -l +100%FREE /dev/VolGroup00/LogVol00
   

6. Finally, lets resize the filesystem

   resize2fs -p /dev/VolGroup00/LogVol00
   

7. Verify the filesystem is larger

   df -h
