Hi all,
I have a script for restoring a database every night to an other postgresql database
root@p2prddnmdbc:~# cat /var/admin/script/restoredb.sh
#/bin/bash
/etc/init.d/postgresql stop
mv /var/log/postgresql/postgresql-9.3-main.log /var/log/postgresql/postgresql-9.3-main.log.old
cd /var/lib/postgresql/9.3/main
psql --host=p2prddnmdbm --username=replicator postgres -c "SELECT pg_start_backup('sync');"
rsync -av --delete
root@10.10.11.1:/var/lib/postgresql/9.3/main/* /var/lib/postgresql/9.3/main/
rm backup_label
chown -R postgres:postgres *
psql --host=p2prddnmdbm --username=replicator postgres -c "SELECT pg_stop_backup();"
/etc/init.d/postgresql start
chmod 777 /var/log/postgresql/postgresql-9.3-main.log
psql -U postgres -c "ALTER USER xxxx WITH PASSWORD 'XXXX';"
psql -U postgres xxxx -c "CREATE EXTENSION dblink;"
root@p2prddnmdbc:~#
But during the day when the user are using the new database we got error like this :
2015-06-25 16:20:58 CEST ERROR: could not read block 257985 in file "base/16386/14064061.1": read only 0 of 8192 bytes
2015-06-22 15:21:11 CEST ERROR: could not read block 256801 in file "base/16386/14064061.1": read only 0 of 8192 bytes
I have check the : filesystem on the vm, on the HW SAN,...
Any idea to fix this problem?
Thanks
