Local storage #11

I used to be able to deploy Local Storage as per https://github.com/marcredhat/upi/blob/master/ocp44-local-storage.adoc

Currently, I can get only small PVs s.a. the ones below.

[root@dell-r730-001 ~]# oc get pv NAME CAPACITY ACCESS MODES RECLAIM POLICY STATUS CLAIM STORAGECLASS REASON AGE local-pv-4ad711f5 384Mi RWO Delete Available marcsc 29m local-pv-64df8c7e 384Mi RWO Delete Available marcsc 29m local-pv-90a727a8 384Mi RWO Delete Available marcsc 29m local-pv-939e5fe4 384Mi RWO Delete Available marcsc 29m local-pv-e5a876b9 384Mi RWO Delete Available marcsc 29m

I can only use /dev/vda1 as /dev/vda4 is not recognized by the Local Storage Operator.

[core@worker-2 ~]$ lsblk -a NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT vda 252:0 0 1000G 0 disk ├─vda1 252:1 0 384M 0 part /boot ├─vda2 252:2 0 127M 0 part /boot/efi ├─vda3 252:3 0 1M 0 part └─vda4 252:4 0 999.5G 0 part └─coreos-luks-root-nocrypt 253:0 0 999.5G 0 dm /sysroot

[core@worker-2 ~]$ lsblk -no FSTYPE /dev/vda4 crypto_LUKS xfs

Increasing the disk size for workers does not help as all the available space goes to /dev/vda4, which is not recognized by the Local Storage Operator.

@marcredhat What I would suggest is that you setup a cluster with 0 or minimal number of workers. Once the cluster is up, you can then add additional nodes (see adding-nodes) and use the --add-disk to add additional disks. These disks will be added as sdb, sdc and so on.

Great suggestion, thanks @kxr !
