VPG container support storageclass question

the VPG container just only support the storageclass of blockdev type, not support the storageclass of filesystem type?

error log:

Task CreateVpgTask on VPG redis_vpg Completed with error : Task Failed on Exception : ZVM-LT Exception: command in pod failed cmd=”chroot /nodeproot blockdev –getsz 192.168.0.156:/data/nfs/default-redis-master-pvc-balabalabala” rt=1 stderr=”blockdev: cannot open 192.168.0.156:/data/nfs/default-redis-master-pvc-balabalabala: No such file or directory”
