Hi list, as by the subject: is it possible to reserve space for specific thin logical volumes? This can be useful to "protect" critical volumes from having their space "eaten" by other, potentially misconfigured, thin volumes. Another, somewhat more convoluted, use case is to prevent snapshot creation when thin pool space is too low, causing the pool to fill up completely (with all the associated dramas for the other thin volumes).
For my 'ideals' thin space reservation (which would be like allocation in advance) would definitely be a welcome thing.
You can also think of it in terms of a default pre-allocation setting. I.e. every volume keeps a bit of space over-allocated while only doing so if there is actually room in the thin volume (some kind of lazy allocation?).
Of course not trying to steal your question here and I do not know if any such thing is possible but it might be and I wouldn't mind hearing the answer as well.
No offense intended. Regards. _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
