Volume MountsLimitations / Known IssuesOn this pageLimitations / Known IssuesBlock Cache Concurrent write operations to the same file from multiple handles in the same replica, or from different replicas, may lead to data corruption. In write operations, data is persisted to the Azure storage account only when close, sync or flush is called. Cached data blocks are not refreshed when the file size remains unchanged after a write operation by another process. File Cache Ensure that Attribute Cache is disabled when using file cache, as an issue/bug with the driver prevents eviction of cached data when the file is opened more frequently than the defined timeout.
