Hi, I am having a nightmare at the moment. I woke up this morning and
my system had panicked. It is a MacPro with a software RAID 01
configuration. I rebooted and the system tried to start, got some way
into the init it appeared even though I did not having it booting
verbosely and then panicked again. The next time it would simply not
recognize any bootable drive. It seems that I can get into single
user mode, but cannot load the root fs.
I drove a couple hours away to an Apple store and we spoke for a
while, but they refused to do anything as they were not allowed to do
so. One fellow there seemed fairly confident that it would rebuild
properly as we had, at that time assumed that a drive was bad. They
listened and one of the drives appeared to sound clunky as though it
had the click of death, so I figured that to be true.
I brought the machine home with a couple new drives to replace the bad
one with, took each drive out and listened to them initialize outside
of the machine as the store was quite noisy and unfortunately that was
the standard initialization of each machine. It appeared as though
there was nothing really physically wrong with the drives, plus when
printing out the raid information from diskutil none showed to be
degraded nor did they have any SMART failure.
I had already, though, tried to replace the drive and it had restarted
to build, but about 10 minutes in the OS panicked again. So then that
was when I thought that perhaps the drive was not bad and then
replaced the new drive with the old one to see what would happen.
Same thing, it tried to rebuild the array and then about 10 minutes
in, it would panic. This panic happened on a Tech Tool Pro boot
eDrive and an install DVD. It also appears to happen when a rebuild
is not running and the OS is simply idling.
I did not have enough time to write the entire panic stack down here,
but could reproduce it and go back and type it up for you in this
email. The first line in the backtrace was had to do with:
com.apple.comkext.aty_lamna
The last line I believe had something to do with the Nvidia graphics
card if I recall correctly.
I am in desperate need to recover this array. I will loose 2 weeks of
work plus all of my family photos and some videos if I cannot rebuild
this. I fear that there is more of a root cause here vs. RAID
failure. Any thoughts or ideas as to how I should track this down and
recover from this issue?
Desperately yours,
-George
