Description Carlos Eduardo Santos 2008-02-05 13:11:48 UTC

After booting, /dev/md* don't exist anymore. Last used kernel: 2.6.19-r5. I've checked kernel raid settings and they're the same. The upgrade was made with make oldconfig.

# grep RAID /usr/src/linux-2.6.19-gentoo-r5/.config
# CONFIG_RAID_ATTRS is not set
# CONFIG_BLK_DEV_3W_XXXX_RAID is not set
# CONFIG_SCSI_AACRAID is not set
# CONFIG_MEGARAID_NEWGEN is not set
# CONFIG_MEGARAID_LEGACY is not set
# CONFIG_MEGARAID_SAS is not set
# Multi-device support (RAID and LVM)
CONFIG_MD_RAID0=y
CONFIG_MD_RAID1=y
# CONFIG_MD_RAID10 is not set
# CONFIG_MD_RAID456 is not set

Reproducible: Always

Steps to Reproduce:
1. Boot gentoo-sources-2.6.23-r6 in a RAID environment

Actual Results:  
no raid detected, no /dev/md*

Expected Results:  
raid detection and /dev/md*

If you can reproduce this with a properly configured kernel (using make oldconfig between 2.6.19 and 2.6.23 is plain crazy and bound to fail), then reopen this bug with emerge --info and dmesg output. Thanks.
