[SOLVED] Arch build - Buffer I/O error

mistertransistor · 2012-02-13 21:33:43

I'm trying to build a new Arch system on a Dell GX240. In fact it's a dual-boot system, but I have manually created the necessary partitions before installing Arch. I start from archlinux-2011.08.19-core-i686.iso on a CD and go through the various stages. When I get to 'install packages' it processes a number and then I get a screenfull of "Buffer I/O error on device sr0 logical block nnnnn" followed by numerous pairs of "SQUASHFS error: unable to read data cache entry ..." and "SQUASHFS error: unable to read page ...".

After all this, package installs continue, and I'm eventually told "package install: success". I continue with the process, and eventually get a bootable Arch hard disk. However, I can't get network connectivity to work - both 'ip addr' and 'ifconfig' are missing commands and ping just says 'network is unreachable'.

I fixed this by replacing my DVD drive by an older CDROM drive - evidently slower as shown by the time to check package integrity. The errors don't occur and ip is present (although ifconfig is not). This looks like to me like a bug in the install process - that kind of error should not be ignored - so I'm documenting this here. That may be the wrong place but I'm a newbie and don't know better.

However I still don't have a working Arch box. I know from previous experience that the core install is not much use (eg pacman libraries are missing) so I try to upgrade using pacman - on to problem 2 ... (next post)

ifconfig etc are in the net-tools package, which you need to install separately.

Sorry - I did not mean that the missing ifconfig should not occur - I meant that dozens of 'Buffer I/O error ..' followed by SQUASHFS errors should not be summarised as 'package install: success'

Oh that sounds just like a bad cd to me...

Then why does 'checking package integrity' before the install succeed?

In any case, should the install not fail if the CD is bad, rather than saying everything is fine?

Well it just keeps trying and trying, checking crc's and making the best of it, i guess in the end it was able to grab all the needed bits.

I don't think so - ip was not working and I could not connect to the network.
Anyway, I've worked around it now.
