Hi all,
Trying to upgrade a system from 9.0-RELEASE to 9.1-PRE from yesterday on
my machine (GEOM+ZFS mirror setup on ada[01]p3), the new kernel becomes
unable to mount root... The only way to recover is to boot from 9.0 kernel.
The disks were already named ada[01] in 9.0, so I suspect nothing there...
I tried
- disabling AHCI in bios (no change seen)
- change cables, check PSU, test disks with smartctl
Here are some bits (via serial console):
ahci0: <ATI IXP600 AHCI SATA controller> port
0xc000-0xc007,0xb000-0xb003,0xa000-0xa007,0x9000-0x9003,0x8000-0x800f
mem 0xfe9ff800-0xfe9ffbff irq 22 at device 18.0 on pci0
ahci0: AHCI v1.10 with 4 3Gbps ports, Port Multiplier supported
ahci0: Caps: 64bit NCQ SNTF MPS AL CLO 3Gbps PM PMD SSC PSC 32cmd CCC 4ports
ahcich0: <AHCI channel> at channel 0 on ahci0
ahcich0: Caps: HPCP
ahcich1: <AHCI channel> at channel 1 on ahci0
ahcich1: Caps: HPCP
ahcich2: <AHCI channel> at channel 2 on ahci0
ahcich2: Caps: HPCP
ahcich3: <AHCI channel> at channel 3 on ahci0
ahcich3: Caps: HPCP
ahcich0: AHCI reset...
ahcich0: SATA connect time=100us status=00000123
ahcich0: AHCI reset: device found
ahcich0: AHCI reset: device ready after 0ms
The difference with 9.0 is after that: here is 9.0's next lines: (same
for ahcich1)
(aprobe0:ahcich0:0:15:0): Command timed out
(aprobe0:ahcich0:0:15:0): Error 5, Retries exhausted
(aprobe0:ahcich0:0:0:0): SIGNATURE: 0000
And 9.1-PRE's:
(aprobe0:ahcich0:0:15:0): NOP. ACB: 00 00 00 00 00 00 00 00 00 00 00 00
(aprobe0:ahcich0:0:15:0): CAM status: Command timeout
(aprobe0:ahcich0:0:15:0): Error 5, Retries exhausted
In both cases ada[01] are detected and available, but with 9.1-PRE I see:
GEOM_RAID: Promise: Disk ada0 state changed from NONE to SPARE.
GEOM_RAID: Promise: Disk ada1 state changed from NONE to SPARE.
(I see the same when I # kldload geom_raid # from running 9.0, doesn't
breaks anything...)
I attach the full boot log with 9.1-PRE (bios with NO-raid nor AHCI
enabled, but this changes nothing in the output)
I could test patches or try any command required to debug this… But for
the moment I don't know where to search (and kernel code is far away
from my current skills in debugging…)
You probably need to clear RAID metadata on the disks as I think that disabling
geom_raid is not possible in 9.1-PRE.
I think that Alexander can help you more here.
The right way is to clear RAID metadata on disks. If it is possible to
boot from any other source, you can just do `graid delete Promise` and
then reboot.
Alternatively it is possible to disable geom_raid module using recently
added loader tunable kern.geom.raid.enable=0. After that your system
should boot and run fine. I would still recommend you to erase metadata,
but after setting that tunable it will be impossible to do it via graid
tool, only with manual dd surgery. In case of Promise format metadata
use up to 63 last sectors of the disk. You can identify respective
sectors to erase by signature "Promise Technology, Inc." in the
beginning of the sector.
