Re: Another slip in the FC6 schedule



You are right, but when you have to deal with 50+ machines you tend to automatize updates for obvious reasons.

Further, no warning has been issued, I just saw the thread by chance.
Even on my personal machines where I do things by hand, I downloaded the new kernels yesterday, rebuilt them with some extra patches (ntfs, initrd dsdt for my buggy laptop etc), installed them together with the old one, tested for one day (they are under heavy load anyway), tested also (and built the drivers for) hardware acceleration, wireless, dumb Conexant modem etc etc. and eventually I deinstalled the old kernel just before reading that message. It is not a big deal to reinstall the previous kernel on those machines,
crossing fingers that nothing happened to the 1k partitions,
much tougher on the cluster, but I really miss the rationale of having a
kernel update in those conditions (the bug was know as far as I understand).

Seriously, I believe this is a big issue. Let me summarize:

a) there was a kernel update for FC5
b) this kernel has a known bug which could results in corrupting
   ext3 filesystems with 1k block size under heavy load
c) ... nevertheless it has been pushed out with no special warning
d) pratically all /boot partitions are ext3 1k (anaconda generated)
e) many partitions on old machine upgraded from previous versions are
   ext3 1k as well
f) experienced users could have much bigger partitions manually
   generated with 1k block size for their own fun/reasons/optimization (I
   personally have counted  already 400 GBytes of 1k, ext3, partitions
   just on my personal laptop, desktop and associated backup disks
   excluding /boot ones). In my case, most of the 1k partitions are such
   because they are subject to heavy loads with many small files

What was the rationale for releasing an official kernel update under such
dangerous conditions? Just "anaconda doesn't generate 1k partitions (not true BTW)"? I still believe Linux is not (yet) Windows


Thank god no. But the growing user base is more and more windows like.

Thankfuly many of us know that you shouldn't push every and all upgrade to
production servers as soon as it comes. And also thankfuly there are
those who do just that.
