Dear sir: I was trying to install all-in-one stx on bare metal environment. I am suprised to find that the drbd allocation was not right. the lsblk is showed below: sda 8:0 0 3.3T 0 disk ├─sda1 8:1 0 1M 0 part ├─sda2 8:2 0 500M 0 part /boot ├─sda3 8:3 0 19.5G 0 part / └─sda4 8:4 0 229G 0 part ├─cgts--vg-scratch--lv 253:0 0 7.8G 0 lvm /scratch ├─cgts--vg-log--lv 253:1 0 7.8G 0 lvm /var/log ├─cgts--vg-extension--lv 253:2 0 1G 0 lvm ├─cgts--vg-pgsql--lv 253:3 0 2G 0 lvm ├─cgts--vg-docker--lv 253:4 0 30G 0 lvm /var/lib/docker ├─cgts--vg-kubelet--lv 253:5 0 10G 0 lvm /var/lib/kubelet ├─cgts--vg-etcd--lv 253:6 0 5G 0 lvm │ └─drbd7 147:7 0 5G 0 disk ├─cgts--vg-backup--lv 253:7 0 5G 0 lvm /opt/backups ├─cgts--vg-dockerdistribution--lv 253:8 0 1G 0 lvm ├─cgts--vg-rabbit--lv 253:9 0 2G 0 lvm └─cgts--vg-platform--lv 253:10 0 10G 0 lvm └─drbd2 147:2 0 10G 0 disk /opt/platform sdb 8:16 0 3.3T 0 disk drbd0 147:0 0 2G 0 disk /var/lib/postgresql drbd1 147:1 0 2G 0 disk /var/lib/rabbitmq drbd5 147:5 0 1024M 0 disk /opt/extension drbd8 147:8 0 1024M 0 disk /var/lib/docker-distribution you can see the drbd 0 1 5 8 are not in right place. They should appear under sda like this: NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 600G 0 disk ├─sda1 8:1 0 1M 0 part ├─sda2 8:2 0 500M 0 part /boot ├─sda3 8:3 0 19.5G 0 part / ├─sda4 8:4 0 229G 0 part │ ├─cgts--vg-scratch--lv 253:0 0 8G 0 lvm /scratch │ ├─cgts--vg-log--lv 253:1 0 7.8G 0 lvm /var/log │ ├─cgts--vg-extension--lv 253:2 0 1G 0 lvm │ │ └─drbd5 147:5 0 1024M 1 disk │ ├─cgts--vg-pgsql--lv 253:3 0 20G 0 lvm │ ├─cgts--vg-docker--lv 253:4 0 30G 0 lvm /var/lib/docker │ ├─cgts--vg-kubelet--lv 253:5 0 10G 0 lvm /var/lib/kubelet │ ├─cgts--vg-etcd--lv 253:6 0 5G 0 lvm │ │ └─drbd7 147:7 0 5G 1 disk │ ├─cgts--vg-backup--lv 253:7 0 25G 0 lvm /opt/backups │ ├─cgts--vg-dockerdistribution--lv 253:8 0 16G 0 lvm │ │ └─drbd8 147:8 0 16G 1 disk │ ├─cgts--vg-rabbit--lv 253:9 0 2G 0 lvm │ │ └─drbd1 147:1 0 2G 1 disk │ ├─cgts--vg-platform--lv 253:10 0 10G 0 lvm │ │ └─drbd2 147:2 0 10G 1 disk │ └─cgts--vg-ceph--mon--lv 253:11 0 20G 0 lvm /var/lib/ceph/mon └─sda5 8:5 0 34G 0 part sdb 8:16 0 200G 0 disk ├─sdb1 8:17 0 199G 0 part /var/lib/ceph/osd/ceph-0 └─sdb2 8:18 0 1G 0 part sdc 8:32 0 200G 0 disk sr0 11:0 1 1.9G 0 rom do you have any method to solve that problem? yours, zhou qingyang
