Here I am :-D

I'm not in disagreement with lowering the lease expiration at all (in 
fact, I have pumped quite a few gigabytes of what is now garbage onto 
the grid while trying to find out a reliable backup strategy).

I don't have any hard facts against 60 days (just like I wouldn't have 
hard facts in favor, or against, 90, 120, or 360 days). Just two things:

1. storage is cheap. We're running at roughly 50% of the capacity 
according to the stats. And the stats depict *all* space used on the 
partition (not only VG2 space), but depict only the (potential) space 
available to VG2 (minus root space, minus reserved space). I don't think 
we need to worry about capacity for the next couple of years.

2. 60 days is not a lot, especially if you run repair cronjobs only 
monthly. I'm personally scheduling repairs every month (with daily 
backups, and weekly synchronizations (="offsite backup uploads")). 
Repairing may be quite expensive (as outlined in some previous mails), 
so I'm trying to not do it toooooo often. Then again, one needs to make 
sure shares are still valid. So -- strike a balance between ... ummm.... 
overhead and redundancy :-D


That said, I'm in favor of *90* days.

That's still only 1/4 of the original retention period, and only 50% 
more than the newly proposed one. Meanwhile, it provides 100% more 
safety if a monthly backup fails... and it allows for a more relaxed 
prolonged overseas holiday.

... just sayin'.

(Actually, no... not just sayin. I'm really against 60 days and propose 
90 instead :D)
