Our product uses Ontap API to enumerate all files in one directory. It is single threaded calling. On some Flex volume with Dedup enabled, the call to file-list-directory-iter-start sometimes returns an error as "Unable to open zapi iterator next file: /etc/.zapi/28609711943882364.next, error=No such file or directory". The if the product starts again to call the function, it succeeds.
We already contacted the technical support engineer and he directed us to use this forum for NA developers to read.
Can someone help to fix this problem. The filer version is 7.3.2.
