metadbs on slices to be used as filesystems

[KenCunningham]

Hi folks. I was wondering whether anyone has any experience of creating state database replicas on slices which will be used for filesystems in Solaris 10. It's my understanding that this is possible, but I haven't quite been able to figure out the sequence of events to follow. If any does have a reliable guide, I'd be interested to see it. Many thanks.

I haven't heard of such a thing... you mean it reserves some area of space in the filesystem for metadbs? Sounds unlikely to me, but I guess anything is possible! Is it specific to a certain filesystem type?

Thanks for that, I thought the same. This (last post on thread) seems to indicate it's a possibility, but perhaps only in opensolaris:

I'll give it a go when I'm back at work tomorrow and post back.

Well, all I can say is that it appears to work. I guess time will tell!

Interesting! So it appears that SVM has the smarts to recognise the metadb on the beginning of the slice and position the data further into it. I expect that means mounting the slice directly is no longer an option though (which may be a concern, say, for a root/boot disk that you might need to boot without SVM).
