Hello, I've an FD that's making too much iowait on the backed up machine. I tried searching info on the subject but nothing useful comes up. Here is an excerpt from the top utility:
top - 18:55:25 up 50 days, 1:48, 23 users, load average: 0.30, 0.32, 0.83 Tasks: 124 total, 1 running, 123 sleeping, 0 stopped, 0 zombie Cpu0 : 2.0%us, 1.0%sy, 0.0%ni, 96.0%id, 0.0%wa, 1.0%hi, 0.0%si, 0.0%st Cpu1 : 2.9%us, 1.0%sy, 0.0%ni, 96.1%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 1032680k total, 1016456k used, 16224k free, 18468k buffers Swap: 2031608k total, 103044k used, 1928564k free, 645912k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 22534 root 20 0 41560 2268 1232 S 6.0 0.2 0:06.32 bacula-fd -c /etc/bacula/bacula-fd.conf 22758 root 20 0 2364 1044 812 R 1.0 0.1 0:01.40 top During normal operation the iowait will stay within 10% limits, however, at some point it jumps to 90-98% and stays that way. I've noticed that even with canceling the job from the director, the iowait on the client will stay at the 90% level. The client is running on Fedora core 9: Linux 2.6.27.9-73.fc9.i686 #1 SMP Tue Dec 16 15:25:05 EST 2008 i686 i686 i386 GNU/Linux Fedora release 9 (Sulphur) I've installed the FD through yum. Can anyone help with more info to what might be causing the problem or where I can find more info on iowait optimizations? Thank you for your help!
