<div style="">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.<br>
<br>
Also, this is sort of predicated by all of your nodes are exactly the same and have exactly the same (or very similar) workload.<br>

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.
<br>
<br>
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 ?<br>
<br>
Thanks and regards,<br>
