安装 hwameistor 发现 sdb 磁盘未创建 pv, vg, 无可用容量 about hwameistor HOT 5 CLOSED

The disk has GPT partition information, use the command to clean up the disk: wipefs -a /dev/sdb, and finally restart local-storage.

from hwameistor.

hwameistor cannot distinguish the disk with the remaining gpt partition, ld is displayed as Available, causing ldc to stagnate in the bound state

# blkid /dev/sdb
/dev/sdb: PTTYPE="gpt" 

# kubectl get ld
NAME             NODEMATCH    PHASE
k8s-master-sda   k8s-master   Bound
k8s-master-sdb   k8s-master   Available


[root@k8s-master ~]# kubectl apply -f ldc.yaml 
localdiskclaim.hwameistor.io/master created
[root@k8s-master ~]# kubectl get ld
NAME             NODEMATCH    PHASE
k8s-master-sda   k8s-master   Bound
k8s-master-sdb   k8s-master   Bound
[root@k8s-master ~]# kubectl get ldc
NAME     NODEMATCH    PHASE   OWNER
master   k8s-master   Bound   local-storage

a GPT partition exist on disk may cause failure when vgcreate, the LocalDisk object should show Bound status.

i think we should fix this.

one suggestion: when discover a disk, check if there is any partition on the disk, if yes, mark the disk/LD as unavailable with the reason. After clean up it manually, make it available then.
