Online capacity expansion of ext4 without downtime

1. Modify the disk capacity of the virtual machine

2. Re-identify the disk capacity

# ls / sys/class/scsi_disk/# echo 1 > / sys/class/scsi_disk/2\: 0: 1\: 0/device/rescan# fdisk-l

3. Resize the target partition

# fdisk / dev/sdb d n p 1 (start block id before entering) wq# partprobe # reload partition information # resize2fs / dev/sdb1 # reload partition size # df-hT # View the partition size after expansion
