Hello! > I'm new to the topic but managed to get a mirrored setup working. > The only problem is the sync speed: After all what Igor has said there is one thing that popped into my mind: Maybe you want to put the metadata onto a non-RAID5-disk. I remember that Lars mentioned a serious performance degradation if the metadata is on a RAID5, because the metadata changes often. With hardware RAID this is not as serious qs with software RAID, because normally there is a big (and battery backed!!) cache on them. The performance degradation seen in synchronisation due to the "slow" metadata blockdevice will also strike in regular use. You may want to do something about it. Please correct me if i'm wrong here! What i would do: Use two disks in a RAID1 configuration for the OS and metadata. You should be fine then. The only problem is: you'll lose available harddisk space. hth, juergen
