from the output above, we see there are lots of failures:(

such as error: failed retrieving file xxx' from mirror.us.leaseweb.net : Operation too slow. Less than 1024 bytes/sec transferred the last 10 seconds

my question is will this installation succeed? if yes, will this failure make trouble to my system?

The installer is able to download the packages from different sites (called mirrors).

When a download fails (or is too slow) it tries the next one but gives you a warning (to inform you so that you can for example remove the slow site from the mirrors list).

If you look at glibc: the installed tried to download it from mirror.us.leaseweb.net noticed that the download was to slow and then tried with success with another mirror.

should i delete mirror.us.leaseweb.net? –  hugemeow Aug 24 '12 at 10:00
    
You can tune the mirror's list but as the system is able to choose the best one you can also use the default settings. –  Matteo Aug 24 '12 at 10:09

pacman is not able to choose the best one – it just tries mirrors from the top of the list to bottom, so it almost always uses the 1st one. –  grawity Aug 28 '12 at 10:57
    
And though unstated, all packages are (attempted) downloaded before the group are installed. If a package wasn't successfully downloaded, you won't try to install any. Your computer will be usable, just like before you tried the update. –  Rich Homolka Oct 30 '12 at 20:59

Arch has a tool called reflector, installable through pacman, that can sort out and tune your mirrorlist.

Just grab reflector: pacman -S reflector

Then run: reflector --verbose -l 5 --sort rate --save /etc/pacman.d/mirrorlist

Wherein 5 is the number of mirrors you want in your list. I always have 6.

I'm an Arch user too and that's one thing I didn't know of, never needed it though; but it's always good to know. –  Xandy Oct 30 '12 at 21:28
