Is there someone can tell me how to fix the Error "The remote server returned an error: (409) Conflict."

Question

I use Automation Runbook to create the Azure Files' snapshot. And I get one error

Exception calling "Snapshot" with "0" argument(s): "The remote server returned an error: (409) Conflict." At line:3 char:1 + $snapshot = $share.Snapshot() + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : NotSpecified: (:) [], MethodInvocationException + FullyQualifiedErrorId : StorageException,

but it was not consistent.

I use the runbook to create the Azure Files snapshots. At first, it can work well, but recently there have some errors of "The remote server returned an error: (409) Conflict."

I use the code as below to create the snapshots everyday.

$context = New-AzureStorageContext -StorageAccountName "storage" -StorageAccountKey "********"
$share = Get-AzureStorageShare -Context $context -Name "test"
$snapshot = $share.Snapshot()

I want to fix the error.

Exception calling "Snapshot" with "0" argument(s): "The remote server returned an error: (409) Conflict." At line:3 char:1 + $snapshot = $share.Snapshot() + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : NotSpecified: (:) [], MethodInvocationException + FullyQualifiedErrorId : StorageException

Try updating the AzureStorage and dependent modules from Modules Gallery under your Automation Account. Modules Gallery > Search for Module > Import. — tush4r
Thanks for your comment, I had checked the Azure Storage module Version (4.6.1) and found it is the newest one. Can you show me more information of the dependent modules? — Arthur
Could you please confirm if you are doing any of these following 409s docs.microsoft.com/en-us/rest/api/storageservices/… — tush4r
@Arthur, just for testing purpose, can you please write a new runbook, and create a new file share, then check if it can work? and also please test it from your pc to see if it works. — Ivan Yang
@Arthur, why not just use try-catch in runbook? if an error throws, just create it again? — Ivan Yang

As per discussed with Arthur, we try to use try-catch as a workaround since we didnot figure out the root cause.

when the create snapshot operation fails, then we can retry more times(like 3 times). The sample code like below:

$RetryIntervalInSeconds = 10 
$NumberOfRetryAttempts = 2 
$CmdOk = $False 
do{ 
try{ *the code I using now $CmdOk = $True} 
catch{ * the error I met $NumberOfRetryAttempts-- Start-Sleep -Seconds $RetryIntervalInSeconds } 
} 
while (-not $CmdOk -and $NumberOfRetryAttempts -ge 0)

Is there someone can tell me how to fix the Error "The remote server returned an error: (409) Conflict."
