<aside> 💡 Hint:

1. If you need to rebuild lots of user volumes(PVC), you can use this shell script to rebuild it quickly.
2. Restriction: The shell script can only use by claim-<username> PVC storage.

• If the operation engineers need to rebuild lots of user volumes, they can easily use a shell script to rebuild all the user volumes.

• Step 3: Use kubectl to check the user volume name.

  $ kubectl -n hub get pvc | grep claim-<username>
  claim-<username>     Bound    <pvc-name>   20Gi   RWO     rook-block     16m
  

• Step 4: Use shell file to rebuild the user volume.
