When installing RAC, I had 2 ASM diskgroups + DG, respectively, + recoverydest: Now + recoverydest has insufficient space, and no redundant asmdisk is created during installation. Only now can the remaining space be recovered. At the same time, two nodes can create asmdisk with virtual machines, then, run the alter diskgrou
