[opensuse-project] 10.3 Alpha1 ISO Metalinks
- From: albryan@xxxxxxxxxxx
- Date: Thu, 15 Feb 2007 20:19:18 +0000
- Message-id: <021520072019.13069.45D4C046000E181B0000330D2200751090020E979D0D040E@xxxxxxxxxxx>
.metalinks were ready for 10.3 Alpha1 ISOs at http://download.packages.ro/metalink/opensuse/ as soon as the mirrors synced. Note, these .metalinks do not yet contain repair information. (Only full file checksums - if someone wants to hack the perl script to include repair info, let me know!)
.metalinks (for 10.2 and 10.3 Alpha1, i386 so far but x86_64 in a few minutes) with repair information are at:
http://www.metalinker.org/samples.html#opensuse
Besides individual .metalinks for each ISO, there is also a .metalink for all 5 CD ISOs.
The latest aria2 (0.10.1, RPMs graciously provided at http://linux01.gwdg.de/~pbleser/rpm-navigation.php?cat=/Network/aria2 ) can autocorrect/repair metalink downloads if they contain chunk checksums. Basically, your finished download should have no errors when it's done, similar to rsync and BitTorrent downloads. And it should be pretty fast (depending on your connection speed) by using multiple mirrors.
>From Tatsuhiro Tsujikawa, aria2 author:
"As of 0.10.0 aria2 supports chunk checksum in Metalink: it validates chunk
checksums while downloading a file like BitTorrent. This gives safer and more
reliable download experience.
1) Before dowload begins: Use this to correct damaged downloads.
2) Realtime hash checking: Validate checksum on the fly like BitTorrent."
Some people had file fragmentation issues if their filesystem was reiserfs.
It would be good to have more comments from people using reiserfs to see if
--file-allocation=prealloc fixes the issue. Please post bug reports or comments
at http://aria2.sourceforge.net/ to help improve it.
--file-allocation=METHOD
Specify file allocation method. METHOD is either none or prealloc.
none doesnt pre-allocate file space. prealloc pre-allocates file
space before download begins. This may take some time depending on
the size of file. Default: none
