Missing BLOBs in ZCS 8.8
To check for missing blobs on an account, you can do the following
Get the user's mailboxID
zmprov gmi user001@example.com
You will see output something like this
mailboxId: 5
quotaUsed: 64498843
Now we will check if there are missing blobs for the account
zxsuite hsm docheckblobs start mailbox_ids 5
You will see output something like this
operationId bdbd8112-8c2f-4f8f-bc7b-a82ef5388378
server mailstore3.example.com
log path /opt/zimbra/log/op_CheckBlobs_bdbd8112-8c2f-4f8f-bc7b-a82ef5388378.log
Now search for the word WARN in the CheckBlobs log
grep WARN /opt/zimbra/log/op_CheckBlobs_bdbd8112-8c2f-4f8f-bc7b-a82ef5388378.log
if there was a missing BLOB, you would see similar output like this
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=
Now, lets restore the missing blob, but first we need the ID of the message volume
zxsuite hsm getAllVolumes
Typically, you should see
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
The output for /opt/zimbra/store is 1
Now lets see what will restored. Keep in mind this is a dry run, nothing is restored yet!
zxsuite --progress backup dorestoreblobs 1
You will see a lot of verbose output, and at the bottom, you will see results similar to this
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
When you are ready to restore the blob, run the same dorestoreblobs command again, but this time add the dryrun false option
zxsuite --progress backup dorestoreblobs 1 dryrun false
You will see a lot of verbose output, and now you will see the number of restored blobs
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
