From ac0034c20fc346cf01f77f95e545f840b928be5c Mon Sep 17 00:00:00 2001 From: Milan Broz Date: Tue, 19 May 2009 10:25:16 +0000 Subject: Use lvconvert --repair in dmeventd DSO (mornfall) This means two things: 1) Non-mirrored LVs will be no longer affected by mirror monitoring. (Before, if you had a LV that went partially missing on a VG where a mirror leg failed, this LV would be removed automatically by dmeventd... Probably not an unrecoverable dataloss bug, but still quite unpleasant.) 2) If enough parallel PV space is available at the time of the mirror failure, the failed devices will be automatically replaced using this spare space. Which (and whether) free space may be used is still not configurable, but is a planned feature. Since it is relatively easy to undo the action by converting the mirror manually, I don't consider this to be a showstopper. In fact, I think the compromise is much better than what we have now. --- daemons/dmeventd/plugins/mirror/dmeventd_mirror.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'daemons/dmeventd/plugins/mirror') diff --git a/daemons/dmeventd/plugins/mirror/dmeventd_mirror.c b/daemons/dmeventd/plugins/mirror/dmeventd_mirror.c index fc610aea..9e89a553 100644 --- a/daemons/dmeventd/plugins/mirror/dmeventd_mirror.c +++ b/daemons/dmeventd/plugins/mirror/dmeventd_mirror.c @@ -152,7 +152,7 @@ static int _remove_failed_devices(const char *device) } /* FIXME Is any sanity-checking required on %s? */ - if (CMD_SIZE <= snprintf(cmd_str, CMD_SIZE, "vgreduce --config devices{ignore_suspended_devices=1} --removemissing --force %s", vg)) { + if (CMD_SIZE <= snprintf(cmd_str, CMD_SIZE, "lvconvert --config devices{ignore_suspended_devices=1} --repair %s/%s", vg, lv)) { /* this error should be caught above, but doesn't hurt to check again */ syslog(LOG_ERR, "Unable to form LVM command: Device name too long"); dm_pool_empty(_mem_pool); /* FIXME: not safe with multiple threads */ -- cgit
