I am running an instance on google cloud and I have attached a spare 500gb disk through the console. On the machine I can only see
$ df -aTh Filesystem Type Size Used Avail Use% Mounted on rootfs rootfs 9.8G 1.3G 8.0G 14% / sysfs sysfs 0 0 0 - /sys proc proc 0 0 0 - /proc udev devtmpfs 10M 0 10M 0% /dev devpts devpts 0 0 0 - /dev/pts tmpfs tmpfs 372M 152K 372M 1% /run /dev/disk/by-uuid/7ad09482-d361-4685-8581-c8a3a12e8103 ext4 9.8G 1.3G 8.0G 14% / tmpfs tmpfs 5.0M 0 5.0M 0% /run/lock tmpfs tmpfs 743M 0 743M 0% /run/shm
I have tried to remove and reattach the disk from the console but I see nothing coming up on the machine. Any clues?
