Re: Help with very slow disks on 3 partitions on a VIO server | |
Ok commands such as mklv are front ends to the Logical Volume manager on the Virtual I/O server. Effectively on the 148Gb disks you have a Logical Volume Manager running on topof a disk with the Logical Volume Manager.
This means that doing a copy on one server will influence the copy on the other.
The only way you can really help this is to allocate one 146Gb disk to one server and the other one to the second LPAR. If you allocate the whole disk that way - not using the logical volume commands - and then create all the file systems on the LPAR it will improve the performance some what.
If you are using disks this way for rootvgs its usually OK as there isn't much writing to the rootvg so you don't often get the problem. Unfortunately you do and I don't have a solution.
