I need to create a RHEL machine on GCP with separate partitions for /home, /tmp, and /var. If I were installing on a physical machine I would simply partition my disk when I install the OS but I can’t seem to figure this out on a GCP virtual machine. I:
- instantiated a new RHEL VM on GCP by selecting an existing one and the "create similar" feature
- created a new disk on GCP with
gcloud compute disks create acas-home --size 200 --type pd-ssd
- attached it to my VM with
gcloud compute instances attach-disk <my-vm-name> --disk acas-home
- formatted it with
sudo mkfs.ext4 -m 0 -E lazy_itable_init=0,lazy_journal_init=0,discard /dev/sdb
- mounted the new partition just once in a temporary folder and copied the original .ssh folder into to to import the authorized_keys file
- added the new disk to /etc/fstab with the following line
UUID=<MY_UUID_VALUE> /home ext4 discard,defaults,nofail 0 2
- mounted the disks with
sudo mount -a
- restarted sshd with
sudo systemctl restart sshd.service
After this, I cannot ssh into the server. I tried simply deleting the authorized_keys file and creating a new one but nothing would do. I also tried adding another authorized keys file to sshd_config, and populating it, with this line but it would not pick it up either:
AuthorizedKeysFile .ssh/authorized_keys /etc/ssh/authorized_keys
What am I doing wrong?
You probably forgot to restore the SELinux contexts for your newly created partition.
restorecon -rv /home
