A. ALTER DISKGROUP misc MOUNT;
B. ALTER DISKGROUP misc DROP DISK misc2;
C. ALTER DISKGROUP misc CHECK ALL NOREPAIR;
D. ALTER DISKGROUP misc RESIZE ALL SIZE 1023m;
E. ALTER DISKGROUP dgroupA ADD DISK '/devices/A*';
Answer: AC
Rebalance operation
Disk group rebalance is triggered automatically on ADD, DROP and RESIZE disk operations and on moving a file between hot and cold regions.

这里的意思是，只有当ADD, DROP, RESIZE操作才会触发rebalance
