From efa593390e70b0e3c39f6b2dca8876b6b1461e41 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Mon, 14 Dec 2009 12:49:49 +1100 Subject: [PATCH] md: don't reset curr_resync_completed after an interrupted resync If a resync/recovery/check/repair is interrupted for some reason, it can be useful to know exactly where it got up to. So in that case, do not clear curr_resync_completed. Initialise it when starting a resync/recovery/... instead.
