After an update stable doesn't boot
Hi
I just did a system update and after I've rebooted it doesn't boot up any more. All I'm getting is a blank screen with a cursor blinking at the top left corner of the screen after the POST has finished. This system was running 7.0-STABLE build in June if I can remember correctly. I can boot the system with a life cd and get into fixit, but I have no idea what to do next. Any ideas as to how I can get it back up? Thanks hamba |

thanks for the quick reply
I followed the normal way of updating /usr/src using csup then make buildworld make buildkernel make installkernel mergemaster -p make installworld mergemaster shutdown -r now Nothing comes up, this is the weird part, I would have though at least to get the loader but it doesn't happen All I see after the POST is a blinking cursor. |

hehe, no problem
I'm using RELENG_7 for the tag I am on the freebsd-stable mailling list as well and was asked to give a little more info on fdisk. Here it is Code:
# fdisk ad12 ******* Working on device /dev/ad0 ******* parameters extracted from in-core disklabel are: cylinders=310101 heads=16 sectors/track=63 (1008 blks/cyl) Figures below won't work with BIOS for partitions not in cyl 1 parameters to be used for BIOS calculations are: cylinders=310101 heads=16 sectors/track=63 (1008 blks/cyl) Media sector size is 512 Warning: BIOS sector numbering starts with sector 1 Information from DOS bootblock is: The data for partition 1 is: sysid 165 (0xa5),(FreeBSD/NetBSD/386BSD) start 63, size 312576642 (152625 Meg), flag 80 (active) beg: cyl 0/ head 1/ sector 1; end: cyl 1023/ head 254/ sector 63 The data for partition 2 is: <UNUSED> The data for partition 3 is: <UNUSED> The data for partition 4 is: <UNUSED> Code:

there are 6 disks on it
ad10 ad12 ad18 ad22 ad6 and ad8 ad12 is where I have Freebsd installed on using UFS, the rest of the drives are all for a zfs pool |
|
|||
no zfs is not compiled into the kernel.
I'll comment them out and unplug the drives. Lets see what happens |
|
|||
hmm, I unplugged all the drives except for ad12 and guess what, it booted
Now to figure out why it failed with all the drives |
|
|||
3 down 3 to go
this looks like it might just work |
|
|||
ah ha
the problem looks like it's coming from the pci raid controller All the internal drives are working fine but as soon as I plug in a drive on the raid controler all the weirdness starts again. thanks for the help |
|
|||
yeah I know and that the controller doesn't have any drives assigned for booting
I had a look and I can't even see an option on the controller to set the drives for booting |
|
|||
one more question
how will zfs handle it if I changed the raid controller on this box? |
|
|||
hehe, never mind
I went into the raid controllers bios and removed everything and rebooted. Now FreeBSD is booting the way it should and zfs is still working the way it always have Thanks for the help, now I can finally go home and get some sleep Have a good night |
