Hi, Thank you Zdenek
You used "makes sure" phrase in your sentence:
"this makes sure you should have files at least 10 days back as well"
I was refering to that !
So the whole thing is about PV metadata area and not /etc/lvm , am I correct?

Hi
Archives in /etc/lvm/archive subdirs are not 'a must have' - they are optional
and purely for admin's pleasure.
So admin can erase them anytime he wants to - but in that case it's probably
more clever to disable archiving in lvm.conf ;) as archiving eats some CPU...
lvm2 itself does *only* care about metadata stored in the 'metadata' area in
PV header - where there is also ring-buffer which typically keeps pretty long
history of all metadata modifications - this buffer has these days ~1MiB in
size. So unless your metadata are pretty big - the history can be relatively
easily extracted also out from this place for i.e. recovery purpose.
I must admit I don't understand the 'make sure' part of your question??
Are you aiming at some particular issue ??
Regards
Zdenek
