Description kvaps 2017-04-06 19:16:05 UTC
Hello, I use overlayfs on back of read only stateless NFSv3 in high availability configuration.

Problem is that overlayfs stores the states of the files of NFSv3,
This is a problem if the someone tries to access the file at the time that server is unavailable for a long time. Right, It return error like "Stale file handle"

And earler even if the server is available again, this file will remain unavailable on overlayfs with the same message.
Although on the lowerdir it has long been available
