From 07011a334fd1e4b641cdbfaf5de7500f7bdc941d Mon Sep 17 00:00:00 2001 From: Michal Suchanek Date: Wed, 6 Jan 2021 14:17:41 +0100 Subject: [PATCH 029/217] ndctl/namespace: Suppress -ENXIO when processing all namespaces. When processing all namespaces and no namespaces exist user gets the default -ENXIO. Set default rc to 0 when processing all namespaces. This avoids confusing error message printed in addition to the message saying 0 namespaces were affected. Before: # ndctl check-namespace all namespace0.0: namespace_check: namespace0.0: check aborted, namespace online error checking namespaces: Device or resource busy checked 0 namespaces # ndctl disable-namespace all disabled 1 namespace # ndctl check-namespace all namespace0.0: namespace_check: Unable to recover any BTT info blocks error checking namespaces: No such device or address checked 0 namespaces # ndctl destroy-namespace all destroyed 1 namespace # ndctl check-namespace all error checking namespaces: No such device or address checked 0 namespaces # ndctl destroy-namespace all error destroying namespaces: No such device or address destroyed 0 namespaces After: # ndctl check-namespace all namespace0.0: namespace_check: namespace0.0: check aborted, namespace online error checking namespaces: Device or resource busy checked 0 namespaces # ndctl disable-namespace namespace0.0 disabled 1 namespace # ndctl check-namespace all namespace0.0: namespace_check: Unable to recover any BTT info blocks error checking namespaces: No such device or address checked 0 namespaces # ndctl destroy-namespace all destroyed 1 namespace # ndctl check-namespace all checked 0 namespaces # ndctl destroy-namespace all destroyed 0 namespaces # ndctl destroy-namespace all destroyed 0 namespaces Note: this does change the return value from -ENXIO to 0 in the cases when no namespaces exist and processing all namespaces was requested.
