→ Applies to: SynetoOS 4.x

Ensure the following parameters are verified before starting the process:

– The datastore must have at least one snapshot without errors before the first faulted snapshot
– You must run a new protection before launching the procedure
– The vm config is taken from the last available snapshot

Step 1. Connect to SynetoOS appliance via SSH as admin

ssh admin@<your_ip_address_or_hostname>

Step 2. Become Super User

sudo su

Step 3. Retrieve a list of all datastore

zfs list

hybrid/backups/LinuxVM                       194K  18.9G    24K  /hybrid/backups/LinuxVM

Step 4. Identify the datastore with the error (datastores can be found in the path /<pool_name>/datastores/)

EXAMPLE

<pool_name>/datastores/TestWin16

Step 6. Create a new PHP file called “fixSnapshotMetaVms.php”

vi fixSnapshotMetaVms.php

Step 7. Copy and paste the following text into the newly created PHP file

#!/usr/bin/php -q<?phpuse Dataset\Snapshot\SnapshotRepository;use Dataset\SynetoMeta\SynetoMetaIO;use Dataset\SynetoMeta\SynetoMetaIOBuilder;require_once 'Lego/autoload.php';$datasetId = $argv[1] ?? null;if (!$datasetId) {  echo "No dataset id provided!\n";  exit(1);}$day = $argv[2] ?? null;if (!$day) {  echo "No date provided!\n";  exit(1);}$repo = new SnapshotRepository();$snapshots = $repo->getForDataset($datasetId);if (!$snapshots) {  echo "Could not find snapshots for the dataset!\n";  exit(1);}$lastSnap = $snapshots[array_key_last($snapshots)];$vmConfig = $lastSnap->getVirtualMachinesAsList();var_dump($vmConfig);$metaIoBuilder = new SynetoMetaIOBuilder();foreach ($snapshots as $snap) {  if ($snap->getCreationDate()->format('Y-m-d') != $day) {    continue;  }  if ($snap->getVirtualMachinesAsList()) {    continue;  }  var_dump($snap->getPath());  $metaIO = $metaIoBuilder->make($snap->getPath());  $metaIO->patch([["op" => "replace", "path" => "/protectedVirtualMachines", "value" => $vmConfig]]);}

Step 8. Run the newly created script (replace <dataset_path> with the path at step 4 and <date:Y-m-d> with the date of the snapshot with the error)

php fixSnapshotMetaVMs.php <dataset_path> <date:Y-m-d>
