The activate_array function works, it's just that it runs "dmraid -ay -i
-p -Z" and the -p option prevents partitions to be activated. Changing
that doesn't work either though, since it looks like dmraid-activate is
never called. I'm not sure how dmraid is supposed to activate the root
device during boot in that case?
** Description changed:
I have installed Precise Pangolin Alpha 2 to a fakeraid stripe, but ubuntu
fails to boot after install.
When choosing recovery option, the boot process times out waiting for root
device and drops to busybox shell.
Running "dmraid -ay" and exiting busybox resumes boot and it continues
normally.
I've added a script in /etc/initramfs-tools/script/local-top/ that run
"dmraid -ay" as a solution.
- The problem seems to be with the dmraid-activate script.
- For example, it expects a device name without "/dev/" (e.g. "sda") however it
is being called from /usr/share/initramfs-tools/scripts/local-top/dmraid script
with the full device name ("e.g. "/dev/sda"). Fixing that didn't solve the boot
issue since the the activate_array function in dmraid-activate does not seem to
work either.
+ I might have identified problems with dmraid-activate script.
+ For example, it expects a device name without "/dev/" (e.g. "sda") however it
is being called from /usr/share/initramfs-tools/scripts/local-top/dmraid script
with the full device name ("e.g. "/dev/sda"). That does not fix the boot issue
since dmraid-activate is not called befoore mounting root.
There might also be antoher bug on line 100 in dmraid-activate (in the awk
script):
# Heximal to decimal conversion array
for (i = 0; i <= 9; i++) hex2dec[i] = i
hex2dec["a"] = 10; hex2dec["b"] = 11; hex2dec["c"] = 12
hex2dec["e"] = 13; hex2dec["d"] = 14; hex2dec["f"] = 15;
Element "e" and "d" appears to have been switched. I'm not entirely sure
what the script is trying to do though.
