While changing the storage account's redundancy from LRS to ZRS in West Europe, but it failed with an error.

Question

I am trying to change the zone redundancy of storage account from LRS to ZRS for west Europe region its failing and giving below error

Answer 1

Customer-initiated redundancy conversion from LRS to ZRS is not supported in all regions. If it’s unsupported, you will receive an error when attempting the change.

You can create a new ZRS account manually and copy the data using Azure Storage Explorer or AzCopy.

See the lists of supported regions for Zone-redundant storage and Geo-zone-redundant storage.

Hi @pranil sitap,

Changing the redundancy of a storage account from Locally Redundant Storage (LRS) to Zone Redundant Storage (ZRS) may fail for several reasons, including limitations based on storage account types or configurations.

In Azure, ZRS is supported for specific managed disk types but is not available for all storage accounts. If your storage account is a ZRS Classic account, you won't be able to convert it directly to ZRS or any other replication type without upgrading it first.

1. Verify Compatibility: Ensure your storage account is compatible with ZRS and not categorized as ZRS Classic.
2. Follow the Migration Process: Check the correct steps for upgrading or migrating your storage account to enable ZRS.
3. Regional Availability: Confirm that ZRS is supported in the West Europe region for the type of storage account you're using.

@pranil sitap
There are certain limitations for the LRS to ZRS change. Can you please check the following limitations and see if any applies to your scenario? Please provide a response for each, it would help me investigate the issue better.

1. If your storage account contains blobs in the archive tier, review the access tier limitations before changing the redundancy type to ZRS. (Yes/No)
   If yes, to convert an LRS account to one that supports zone-redundancy, first move the archived blobs to a storage account that supports blobs in the archive tier. Then convert the source account to ZRS.
2. Boot diagnostics doesn't support premium storage accounts or zone-redundant storage accounts. Any conversion attempts to add zonal redundancy, such as LRS to ZRS or GRS to GZRS, will fail. To convert your account to a zone-redundant SKU, disable boot diagnostics on your account and resubmit the request. (Boot diagnostics enabled on your account. (Yes/No)
3. The type of conversion supported depends on the storage account type. For more information, see the storage account table. (Is your account type - premium Page blob or Standard general purpose v1 or ZRS Classic?)
4. If you performed a customer-managed account failover to recover from an outage for your GRS or RA-GRS account, the account becomes locally redundant (LRS) in the new primary region after the failover. Conversion to ZRS or GZRS for an LRS account resulting from a failover isn't supported. For more information, see Failover and failback. (Is this LRS account resulting from a failover - (Yes/No)
5. You can't convert storage accounts to zone-redundancy (ZRS, GZRS, or RA-GZRS) if either of the following cases are true: (Any of these two applies to your case? Yes/No)
   • NFSv3 protocol support is enabled for Azure Blob Storage
   • The storage account contains Azure Files NFSv4.1 shares with public endpoint access enabled

Let me know the details and I can further investigate.
