I'm afraid I don't know how to do it. Can you please provide me with the necessary command so I may help?

Cheers

The latest script has an issue, I guess somewhere with a closing fi-if because the complain about parentheses seems fine to me; maybe I am wrong. But anyway, I have downloaded the 0.55 edition and ran the test. Here you are

Thanks for your posting the result.
In my installed debian (on non-lvm partition), boot info script version 0.60 correctly worked and posted the result.
Maybe, version 0.60 has some bug in dealing LVM or so, about parentheses and/or if-fi.

The result of boot info script is interesting. I will analyze more.
But boot info script version 0.55 may give wrong report for new version of GRUB2 or on LVM, though I am not sure.

Anyway, thank you very much for posting the result.

Have you worked this one out? Or made any progress? I have a very similar case. I have done two installs/upgrades on almost identical machines and have the "wait + fd0 read error + wait" issue on one machine only.

Here's what I did (or better say what I can remember).

• had migrated my system from 32 bit to 64 bit Debian Lenny using debootstrap on the swap partition on a serial console
• upgraded to grub2 (1.96 haha!)
• all looking good, now convert to a raid1 ready system
• I copied my basic system from /dev/sda1 to /dev/md1 (consisting of a degraded array of two devices with only /dev/sda2 present)
• rebooted into that system - all fine
• created /dev/md0 consisting of /dev/sda1 and a missing device
• copied my system back to /dev/md0
• ran update-grub etc
• reboot
• the wait + fd0 read error + wait happens. The system boots still okay but it's slightly disconcerting and anotehr sysadmin here might panic and just hit reset while waiting

I've tried most of the things I've found - like grub-install --no-floppy --recheck, ran update-grub two million times etc. I can't try the scarier things like dd'ing sda because the machine is in the co-lo center.
Anything else I could try?

I got the same error and disabled the floppy drive in BIOS. All is well now

I got the same error and disabled the floppy drive in BIOS. All is well now

Nice method! Cheers!

[Al.Harris]

Same error here. Running software mirroring with a new install of Wheezy. I disabled the floppy through the BIOS settings and that took care of it for me as well. Thanks for the help.
