Greetings,
I have a 4 server postgresql-9.1.3 cluster (one master doing streaming
replication to 3 hot standby servers). All of them are running
Fedora-16-x86_64. Last Friday I upgraded the entire cluster from
Fedora-15 with postgresql-9.0.6 to Fedora-16 with postgresql-9.1.3.
I'm finding that I cannot runpg_basebackup at all, or it blocks all
SQL queries from running until pg_basebackup has completed (and the
load on the box just takes off to over 75.00). By "blocks" I mean
that any query that is submitted just hangs and does not return at all
until pg_basebackup has stopped. I'm assuming that this isn't
expected behavior, so I'm rather confused on what is going on. The
command that I'm issuing is:
pg_basebackup -v -D /mnt/backups/backups/tmp0 -x -Ft -U postgres
Can someone provide some guidance on how to debug this?
thanks!
