RE: RAID chunk size configuration from kickstart

Well in my case the nodes did have exact same config so that is not issue.
But if kickstart command itself supported additional parameters it would have been lot simpler to specify chunk size. As in other cases we need to worry about different devices names(sd*/cciss*) etc and do all of this stuff in %post section to set the chunk size.

But just to confirm , so there is no way this can be done using kickstart 'raid' command and has to be done using tools like mdadm in %pre / %post sections ?

As far as I know, not for the root fs which "normally" shouldn't be a problem since setting the chunk size is a performance tuning task and you typically don't do high load tasks against your root fs (Well I don't anyway). So, I'd suggest simply building a small root fs using the normal kick start methods, then elsewhere in your post section, manually create the raid device and file-system where you need to set the chunk size. Also, this is sort of predicated by all of your nodes are exactly the same and have exactly the same (or very similar) workload. -C

Hi , I am trying to deploy software raid setup using kickstart and was wondering if I can specify chunk-size as parameter in kickstart file.I am using RHEL 6. I didn't see any documentation for this parameter in kickstart. The default installation seems to be using 512K as chunk size whereas I would like to set it to 8MB . This is new device configuration and there is nothing configured on system before this. If kickstart does not allow setting this parameter , Is there another way in %pre , %post sections where we can change it ? How else this parameter could be set for '/' , '/boot/' partitions on clean install ? Thanks and regards, Jay
Any suggestions about how this could be done ? -Jay
