Overview
Recreating a blank storage clears all the data and acts as a fresh storage but has the same properties as it had initially with users still pointing to it.
📝 Note
This would trigger a full backup for the users belonging to this storage and same has to be informed to the customer prior to performing these steps.
This article addresses the following scenarios:
Recreating a blank storage when there are minimal chances of getting the storage back to a healthy status.
Customer wants to migrate to another server, without moving the user data.
To move users from unhealthy or irrecoverable storage to a new storage and the movement is failing due to some issues.
To recreate primary storage from HA (High Availability) incase of corruption; however, additional steps are required to reset the seeding.
📝 Note
Do not use this article to create secondary storage. For secondary storate, the only option would be to delete the storage and recreate the secondary storage and its associtaed HA policy.
Recreating blank storage
Stop all the Druva inSync Master services along with the storage node services if applicable.
Open the Task Manager on the Master & Node servers and end any inSync tasks, if found pending.
Rename the following folders to.Oldfor the storage to be recreated:
__bynamodata__
__bynamolog__
__bynamodb__Take a dump ofinSyncConfigDB.
Connect to theinSyncConfigDBand set the following column values for the Storage to '0'.
Ready = 0
Mount_Gen = 0Start all the inSync Master services and check if the storage is healthy. If healthy, perform the remaining steps.
Stop all the inSync Master services.
Change the value for "FORCE_FULLSCAN" in the inSyncServer.cfg to 1 (which is True).
Start all the inSync Master services.
Delete the.Oldfolders, after verifying whether one complete backup is done for all devices.
Resetting seeding
📝 Note
Perform these steps only when you face issues with the primary storage, which is a part of the HA Policy.
Connect to inSyncDbgConsole.exe.
C:\Program Files\Druva\inSync Server>inSyncDbgConsole.exe serverImport the following modules and run the following one-by-one:
from inSyncLib import inSyncConfigDB
from inSyncLib import inSyncUser
inSyncConfigDB
inSyncUser.DeviceGet the details of the Storage and Device by the following scripts one-by-one and change the "DeviceID" and "StorageID" by appropriate value.
inSyncUser.Device.get(DeviceID)
inSyncConfigDB.Storage.get(StorageID)
st=inSyncConfigDB.Storage.get(StorageID)
st.scookieRun the following one-by-one using appropriate space as listed below and change the StorageID with the appropriate value without using qoutes (''). Make sure to use tab to provide appropriate space before each script.
for u in inSyncUser.User.select():
if u.storageID == 'StorageID':
for d in inSyncUser.Device.selectBy(userID=u.id):
if d.hastatus == False:
d.set_devicecookie(Tasks.getStorageCookie('StorageID'))
Run the following to check the HAStatus for a Device and change the DeviceID with appropriate ID.
inSyncUser.Device.get(DeviceID)
