Hi guys,
I've got a 128GB server with SATA disks.. and I'm having I/O issue....
NO! I Can't change the disks to SAS or SSD =\
Anyway... just wanna understand the parameters below:
[root@741293-03 ~]$ sysctl -a | grep dirty
vm.dirty_background_ratio = 20
vm.dirty_background_bytes = 0
vm.dirty_ratio = 25
vm.dirty_bytes = 0
vm.dirty_writeback_centisecs = 500
vm.dirty_expire_centisecs = 3000
Would be that a good value to work with?
Can you guys tell me what are you using at the moment?
cheers
