To check for missing blobs on an account, you can do the following<br>
 
 
 
Get the user's mailboxID<br>
 
 
 
<code><pre>
 
zmprov gmi user001@example.com
 
</pre></code>
 
 
 
You will see output something like this<br>
 
<code><pre>
 
mailboxId: 5
 
quotaUsed: 64498843
 
</pre></code>
 
 
 
Now we will check if there are missing blobs for the account<br>
 
 
 
<code><pre>
 
zxsuite hsm docheckblobs start mailbox_ids 5
 
</pre></code>
 
 
 
You will see output something like this<br>
 
<code><pre>
 
operationId                              bdbd8112-8c2f-4f8f-bc7b-a82ef5388378
 
server                                    mailstore3.example.com
 
log path                                /opt/zimbra/log/op_CheckBlobs_bdbd8112-8c2f-4f8f-bc7b-a82ef5388378.log
 
</pre></code>
 
 
 
Now search for the word WARN in the CheckBlobs log<br>
 
<code><pre>
 
grep WARN  /opt/zimbra/log/op_CheckBlobs_bdbd8112-8c2f-4f8f-bc7b-a82ef5388378.log
 
</pre></code>
 
 
 
if there was a missing BLOB, you would see similar output like this<br>
 
<code><pre>
 
2017-08-22 15:16:53,877 WARN Missing Blob file: Mailbox id: 5 - Item id: 4610 - Revision: 8720 - Blob path: /opt/zimbra/store/0/5/msg/1/4610-8720.msg - Size: 1859 - Digest: dYV2+dXtH9AUAHH4au1jWquWgCeBCz7XpsYtHza0ofw=
 
</pre></code>
 
 
 
Now, lets restore the missing blob, but first we need the ID of the message volume
 
<code><pre>
 
zxsuite hsm getAllVolumes
 
</pre></code>
 
 
 
Typically, you should see<br>
 
<code><pre>
 
primaries
 
                id                                                          1
 
                name                                                        message1
 
                path                                                        /opt/zimbra/store
 
                compressed                                                  false
 
                threshold                                                  4096
 
                storeType                                                  LOCAL
 
                isCurrent                                                  true
 
                volumeType                                                  primary
 
secondaries                           
 
        indexes                               
 
 
 
                id                                                          2
 
                name                                                        index1
 
                path                                                        /opt/zimbra/index
 
                compressed                                                  false
 
                threshold                                                  4096
 
                storeType                                                  LOCAL
 
                isCurrent                                                  true
 
                volumeType                                                  index
 
</pre></code>
 
 
 
The output for /opt/zimbra/store is 1<br>
 
 
 
Now lets see what will restored. <strong>Keep in mind this is a dry run, nothing is restored yet!</strong><br>
 
<code><pre>
 
zxsuite --progress backup dorestoreblobs 1
 
</pre></code>
 
 
 
You will see a lot of verbose output, and at the bottom, you will see results similar to this<br>
 
<code><pre>
 
Total blobs volume fixed: 0
 
Total blobs checked: 8156
 
Total broken blobs: 1
 
Total restorable blobs: 1
 
Total unrestorable blobs: 0
 
Total failed blob restores: 0
 
Total restored blob: 0
 
</pre></code>
 
 
 
When you are ready to restore the blob, run the same dorestoreblobs command again, but this time add the <strong>dryrun false</strong> option<br>
 
<code><pre>
 
zxsuite --progress backup dorestoreblobs 1 dryrun false
 
</pre></code>
 
 
 
You will see a lot of verbose output, and now you will see the number of restored blobs<br>
 
<code><pre>
 
Total blobs volume fixed: 0
 
Total blobs checked: 8156
 
Total broken blobs: 1
 
Total restorable blobs: 1
 
Total unrestorable blobs: 0
 
Total failed blob restores: 0
 
Total restored blob: 1
 
</pre></code>
