Hi In a situation where I have say two drives, with one being a mirror of the other through LSM. This is a system drive with the root partition being mirrored. Each drive is on a separate KZPSA controller. If I take a hard drive hit/crash on either drive can I expect the system to remain running using the mirrored system drive i.e. the remaining drive? I believe from what I have read this is the case, but I am trying to find out whether there are any unique situations where I will not remain running. Also, what limits migh I have and/or things you should watch for if you want to ensure uptime, and performance? Cheers Steve [Posted by WWW Notes gateway]

Yes, assuming everything on these drives were mirrored including primary swap, /usr, etc. > Also, what limits migh I have and/or things you should watch for if you > want to ensure uptime, and performance? Mirror secondary swap (if present) also improves availability. Also, mirroring across controllers, as you did with root, helps both availability and performance. [Posted by WWW Notes gateway] | |||||
