From 04e673f14e31c60e4c9cde9072bcec610fe3884b Mon Sep 17 00:00:00 2001 From: Pranith Kumar K Date: Mon, 31 Dec 2012 10:03:32 +0530 Subject: protocol/client: Periodically attempt reopens If the brick is taken down and the hard disk is replaced and the brick is brought back up, the re-opens of the open-fds will fail because the file is not present on the brick. Re-opens are not attempted even if the files are re-created by self-heal until the brick is brought down after the files are re-created and brought back up. This is a problem with a VM-store in a replica-setup. Until the fd is re-opened the writes will never happen on the brick where the hard-disk is replaced. To handle this situation gracefully, client xlator is enhanced to perform finodelk, fxattrop, writev, readv using anonymous fds if the file is yet to be re-opened. If the fop succeeds then client xlator attempts re-open.
