While removing missing blobs by using "zmblobchk" command on server, following error message is observed:

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


From ZCS 8.8.x, Zimbra has introduced NG modules which includes the HSM NG module and also replaces the legacy 'zmblobchk' functionality which is used to check the consistency of the blob store. To avoid the error, use the given command line options with HSM NG modules :

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
