When customer tried removing missing blobs by using "zmblobchk", get an error message:

"invalid request: org.openzal.zal.extension.InternalOverrideStoreManager is not supported".


From ZCS 8.8.x Zimbra introduced NG modules which included the HSM NG module and replaced the legacy zmblobchk functionality to take care of blob check process.

Command line options
  • Run the Following command line to check the blobs.
zxsuite hsm doCheckBlobs start
  • Perform a BLOB coherency check on volumes 1 and 3
zxsuite hsm doCheckBlobs start volume_ids 1,3
  • Perform a BLOB coherency check on mailboxes 2,9 and 27
zxsuite hsm doCheckBlobs start mailbox_ids 2,9,27
  • Unrestorable missing blobs should be removed from the store using following command line,
zxsuite hsm doCheckBlobs start missing_blob_delete_item true
