Hi All I have an Asterisk 1.8.32.3 instance that will at random intervals stop logging CDR data to MSSQL via FreeTDS. On investigation I'll find that the FreeTDS module has been unloaded somehow. It is not listed in cdr show status or show module like. Trying module load cdr_tds results in module cdr_tds does not provide a license key and the module is not loaded. The only way to get

Hi, is it possible to use the new "halo" feature to create a replica 2 volume on 2 bricks that are located in 2 different regions (10+ ms latency) so to be able to write to both nodes from each region without the need to a synchronous confirmation of the other node? Does this page includes the most up to date /complete docs about that feature?

G'day, I'm backing up production MySQL database servers. The tables are almost all MyISAM. My plan is to use MySQL binary logging and then rsync the binary logs offsite hourly. The binary log files are only appended to, with new queries logged at the end of the file. So I'm assuming the rsync algorithm will be highly effective at reducing the bandwith required to transfer these

Hi,all I did some test about MySQL''s Insert performance on ZFS, and met a big performance problem,*i''m not sure what''s the point*. Environment 2 Intel X5560 (8 core), 12GB RAM, 7 slc SSD(Intel). A Java client run 8 threads concurrency insert into one Innodb table: *~600 qps when sync_binlog=1 & innodb_flush_log_at_trx_commit=1 ~600 qps when sync_binlog=10

So I got dashboard up and running on our production system on Thursday before I left. Within 48 hours it had completed filled the /var filesystem. The ibdata1 file is currently at 8GB in size. 1. What size should I expect for ~500 nodes reporting every 30 minutes? 2. Are there some database cleanup scripts which I have managed to overlook that need to be run? -- Jo Rhett Net Consonance :

we have multiple servers approx 10 and each has about 100 GB of data in the /var/lib/mysql dir , excluding tar , mysqldump and replication how do we take backup for these databases on to a remote machine and store them datewise , ( the remote machine is a 2TB HDD ) currently tar is not feasible as the data is too huge and the same goes with mysqldump suggestion will be of great help --
