File bug-1158628_08-lv_manip-add-synchronizations.patch of Package lvm2.16878
From 4b1dcc2eebb27cae54b4c618ab31072bdb230ea9 Mon Sep 17 00:00:00 2001 From: Zdenek Kabelac <zkabelac@redhat.com> Date: Mon, 26 Aug 2019 13:28:17 +0200 Subject: [PATCH] lv_manip: add synchronizations New udev in rawhide seems to be 'dropping' udev rule operations for devices that are no longer existing - while this is 'probably' a bug - it's revealing moments in lvm2 that likely should not run in a single transaction and we should wait for a cookie before submitting more work. TODO: it seem more 'error' paths should always include synchronization before starting deactivating 'just activated' devices. We should probably figure out some 'automatic' solution for this instead of placing sync_local_dev_name() all over the place... --- lib/metadata/lv_manip.c | 14 +++++++++++--- lib/metadata/snapshot_manip.c | 5 +++++ lib/metadata/thin_manip.c | 6 ++++++ tools/lvconvert.c | 12 ++++++++++++ 4 files changed, 34 insertions(+), 3 deletions(-) diff --git a/lib/metadata/lv_manip.c b/lib/metadata/lv_manip.c index af3a16fe2d..6451368772 100644 --- a/lib/metadata/lv_manip.c +++ b/lib/metadata/lv_manip.c @@ -5830,9 +5830,17 @@ out: ret = 1; bad: - if (activated && !deactivate_lv(cmd, lock_lv)) { - log_error("Problem deactivating %s.", display_lvname(lock_lv)); - ret = 0; + if (activated) { + if (!sync_local_dev_names(lock_lv->vg->cmd)) { + log_error("Failed to sync local devices before deactivating LV %s.", + display_lvname(lock_lv)); + return 0; + } + + if (!deactivate_lv(cmd, lock_lv)) { + log_error("Problem deactivating %s.", display_lvname(lock_lv)); + ret = 0; + } } return ret; diff --git a/lib/metadata/snapshot_manip.c b/lib/metadata/snapshot_manip.c index 65d8dbd13f..d105942c0f 100644 --- a/lib/metadata/snapshot_manip.c +++ b/lib/metadata/snapshot_manip.c @@ -292,6 +292,11 @@ int vg_remove_snapshot(struct logical_volume *cow) if (is_origin_active && lv_is_virtual_origin(origin)) { + if (!sync_local_dev_names(origin->vg->cmd)) { + log_error("Failed to sync local devices before deactivating origin LV %s.", + display_lvname(origin)); + return 0; + } if (!deactivate_lv(origin->vg->cmd, origin)) { log_error("Failed to deactivate logical volume \"%s\"", origin->name); diff --git a/lib/metadata/thin_manip.c b/lib/metadata/thin_manip.c index b9c01ee215..f94797620f 100644 --- a/lib/metadata/thin_manip.c +++ b/lib/metadata/thin_manip.c @@ -529,6 +529,12 @@ int update_pool_lv(struct logical_volume *lv, int activate) } } + if (!sync_local_dev_names(lv->vg->cmd)) { + log_error("Failed to sync local devices LV %s.", + display_lvname(lv)); + return 0; + } + if (activate && !deactivate_lv(lv->vg->cmd, lv)) { log_error("Failed to deactivate %s.", display_lvname(lv)); diff --git a/tools/lvconvert.c b/tools/lvconvert.c index ebc22433f8..31f9296769 100644 --- a/tools/lvconvert.c +++ b/tools/lvconvert.c @@ -2513,6 +2513,12 @@ static int _lvconvert_cache_repair(struct cmd_context *cmd, /* TODO: any active validation of cache-pool metadata? */ deactivate_mlv: + if (!sync_local_dev_names(cmd)) { + log_error("Failed to sync local devices before deactivating LV %s.", + display_lvname(mlv)); + return 0; + } + if (!deactivate_lv(cmd, mlv)) { log_error("Cannot deactivate pool metadata volume %s.", display_lvname(mlv)); @@ -2520,6 +2526,12 @@ deactivate_mlv: } deactivate_pmslv: + if (!sync_local_dev_names(cmd)) { + log_error("Failed to sync local devices before deactivating LV %s.", + display_lvname(pmslv)); + return 0; + } + if (!deactivate_lv(cmd, pmslv)) { log_error("Cannot deactivate pool metadata spare volume %s.", display_lvname(pmslv)); -- 2.24.0
