在Hetzner云卷上扩展主Linux分区

Question

我有带有20 of /sda的Hetzner云服务器&另外还有30 of的/sdb，如何扩展/sda？

Answer 1

如果卷实际上是可扩展的，那么如果在最后一行使用ext4，则可以使用以下命令。

#scan for disk-changes if those happened in a vm-environment by $host
echo 1 > /sys/block/sda/device/rescan
#install cloud-guest-utils which provide `growpart`
yum install cloud-utils-growpart
#extend partition to maximum available size
growpart /dev/sda 1
#extend ext4?
resize2fs /dev/sda1
