FreeBSD agserver.home 8.2-RELEASE-p2 FreeBSD 8.2-RELEASE-p2 #3: Thu Jul 28 15:32:49 EEST 2011 root@agserver.home:/usr/obj/usr/src/sys/agserver amd64
>Description:
FreeBSD installed on mirror (RAID0).
Controller based on JMicron (JMB363) chip. In some builds of FreeBSD I've found little problem with pseudo-raid cards. After upgrading FreeBSD from version RELEASE-8.0 up to RELEASE-8.2 my server stop boot. I'm tried also 9.0-CURRENT.
>From kernel log I see that problem in mounting of root file system which placed on RAID0 array. Pseudo-RAID controller no more detected by kernel.
After short investigation was found root of problem. In new releases ATA cards registered as "atapci" devices. So, "ata-raid" driver in function 'ata_raid_read_metadata' can't find pseudo-raid controller.
After short fix my server successfully booted.
>How-To-Repeat:
Install in server pseudo-raid card and try to find any (previously created) raid arrays.
>Fix:
In file "ata-raid.c":
static int
ata_raid_read_metadata(device_t subdisk)
{
-- devclass_t pci_devclass = devclass_find("pci");
++ devclass_t pci_devclass = devclass_find("atapci");
