And first, fix clock skew, check all nodes using the same NTP server and time Placement Groups (PGs) that remain in the active status, the active+remapped status or the active+degraded status and never achieve an active+clean status might indicate a problem with the Is there anyone who can explain what went wrong and how to fix the issue?
