From 46ed4fbffa67c423be6233a01e2fdf220ca8f5f0 Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Wed, 28 Nov 2012 12:28:24 -0800 Subject: libceph: remove 'osdtimeout' option (cherry picked from commit 83aff95eb9d60aff5497e9f44a2ae906b86d8e88) This would reset a connection with any OSD that had an outstanding request that was taking more than N seconds. The idea was that if the OSD was buggy, the client could compensate by resending the request. In reality, this only served to hide server bugs, and we haven't actually seen such a bug in quite a while. Moreover, the userspace client code never did this. More importantly, often the request is taking a long time because the OSD is trying to recover, or overloaded, and killing the connection and retrying would only make the situation worse by giving the OSD more work to do.
