 ## Prerequisites
 
-### Step 1: Create a StorageClass 
+Before proceeding, ensure the following Prerequisites are met:
 
-To begin, you will need to create a StorageClass that defines the properties of the snapshot to be restored. Refer to [Storage Class Parameters](../../replicated-pv-mayastor/configuration/rs-storage-class-parameters.md) for more details. Use the following command to create the StorageClass:
-
-:::info
-Currently, restores are thin-provisioned volumes created from a snapshot, Therefore, the storage class for the restored volume must also specify `thin: "true"`.
-:::
-
-**Command**
-
-```
-cat <<EOF | kubectl create -f -
-apiVersion: storage.k8s.io/v1
-kind: StorageClass
-metadata:
-  name: mayastor-3-restore
-parameters:
-  protocol: nvmf
-  repl: "3"
-  thin: "true"
-provisioner: io.openebs.csi-mayastor
-EOF
-```
-
-**YAML**
-
-```
-apiVersion: storage.k8s.io/v1
-kind: StorageClass
-metadata:
-  name: mayastor-3-restore
-parameters:
-  protocol: nvmf
-  repl: "3"
-  thin: "true"
-provisioner: io.openebs.csi-mayastor
-```
-
-:::note
-The name of the StorageClass, which, in the example above, is **mayastor-3-restore**.
-:::
-
-### Step 2: Create a Snapshot 
-
-You need to create a volume snapshot before proceeding with the restore. Follow the steps outlined in [this guide](snapshot.md) to create a volume snapshot.
-
-:::note
-The snapshot's name, for example, **mayastor-pvc-snap**.
-:::
+- A volume snapshot has already been created.
+- A compatible StorageClass is available for the restore operation.
+- A snapshot has been created for the source volume. Follow the steps outlined in the [Volume Snapshots Documentation](snapshot.md) to create a volume snapshot.

@@ -56,6 +56,24 @@ The `agents.core.capacity.thin` spec present in the Replicated PV Mayastor helm
 
 The parameter `allowVolumeExpansion` enables the expansion of PVs when using Persistent Volume Claims (PVCs). You must set the `allowVolumeExpansion` parameter to `true` in the StorageClass to enable the expansion of a volume. In order to expand volumes where volume expansion is enabled, edit the size of the PVC. Refer to the [Resize documentation](../replicated-pv-mayastor/advanced-operations/resize.md) for more details.
 
+## "formatOptions"
+
+The parameter  `formatOptions` allows you to specify additional formatting options to be used when formatting a device with a filesystem. By default, Replicated PV Mayastor uses the `ext4` filesystem to format devices. Depending on the `fsType` parameter, refer to the [Linux FS Documentation](https://man7.org/linux/man-pages/man8/mkfs.8.html) for supported formatting options.
+
+## "overrideGlobalFormatOpts"
+
+Replicated PV Mayastor provides a Helm key to define global `xfs` formatting options. These global options are applied to all volumes formatted with `xfs`. To override the global formatting options for a specific volume, set `overrideGlobalFormatOpts` to `true`. If both `formatOptions` and global Helm-defined options are specified for `xfs` volume, they will be concatenated. The `formatOptions` parameter can be used to add extra flags alongside the defaults.
+
+For editing global options, set `overrideGlobalFormatOpts: true` and pass the edit flags in formatOptions.
+ 
+For example:
+If global options are `-m bigtime=0 -m inobtcount=0` and if you want to use different options for a specific volume, such as `-m bigtime=1 -m inobtcount=1` then configure the volume with:
+
+```
+overrideGlobalFormatOpts: true
+formatOptions: "-m bigtime=1 -m inobtcount=1"
+```
