Thank you for the excellent information and suggestions. I would like to try using mdadm, but had some trouble compiling it. Also, please see notes on raid5 modules below. > -----Original Message----- > From: Neil Brown [mailto:neilb@notabene]On Behalf Of Neil Brown > Sent: Monday, May 20, 2002 5:27 AM > To: cwebster@ec.rr.com > Cc: linux-raid > Subject: Re: Software RAID Stopped Working With Aurora Kernel > > > On Sunday May 19, cwebster@ec.rr.com wrote: > > Looking for help from list members in resolving software RAID problems. > > Here is the help: > > 1/ You seem to have two copies of raid5.o which seems to be confusing > modprobe. > I don't know why, but in one instance it tried to load > /lib/raid5.o > and gets :unresolved symbol md_unregister_thread_R4ba824f9 > > The other time it correctly loads > /lib/modules/2.4.18-0.92sparc/kernel/drivers/md/raid5.o > > I suggest removing /lib/raid5.c Strangely, the only time this error occurred was when I tried to boot with "md0" devices listed in /etc/fstab. I don't know why it reported this path. There are no modules directly under /lib. Here's where all the modules are. I will remove all but the current kernel modules. In fact, I'll be removing all the 2.2 kernels since I can't boot them any more anyway.
