I have SQL Server AOAG 2014 with 3 replicas. 2 Syncronous Commit with Automatic Failover and 1 (BCP) Asynchronos with Manual Failover.
It is a DEV environment and I scheduled log backups every 15 mins.
BCP Replica AOAG Database went into "NOT SNCHRONIZING\SUSPECT" mode.
When I checked the logs it says LOG DRIVE is 100 GB and it is completely occupied with this specific Database Log.
When I checked SYS.DATABASES --> Log_reuse_wait_desc -- I have seen "AVAILABILITY REPLICA".
I tried to backup log of this particular database but still I cannot shrink this particular database.
Finally , I have to re-initialize the database by removing it from AOAG and then by re-adding. then backup log for this particular DB and shrink it . This fixed the issue.
What else can I do for this particular situation.
