I was able to re-start my raid array via: $server: mdadm -A /dev/md/0 /dev/hde1 /dev/hdg1 ... 2 drives started ... The problem is (I believe) with the scan option. The init.d/mdadm uses the scan option and fails to activate the array. Here is a discussion on this topic: http://www.mail-archive.com/linux-raid@vger.kernel.org/msg03242.html Reverting to mdadm 2.1 fixed the problem. vapier@gentoo.org 2006-01-16 17:32:24 0000 Created an attachment (id=77308) mdadm-2.2-update-segv.patch try this patch and see if it fixes things for you fleshy_ai@hotmail.com 2006-01-16 18:10:05 0000 (In reply to comment #1) > Created an attachment (id=77308) [edit] > mdadm-2.2-update-segv.patch > > try this patch and see if it fixes things for you > Sorry, I am relatively new to Gentoo and the portage system. How would I apply this and make portage not replace it? vapier@gentoo.org 2006-01-16 18:20:00 0000 http://www.gentoo.org/doc/en/bugzilla-howto.xml#doc_chap8 should cover it fleshy_ai@hotmail.com 2006-01-16 18:57:42 0000 (In reply to comment #3) > http://www.gentoo.org/doc/en/bugzilla-howto.xml#doc_chap8 should cover it > Thanks for your help. That patch and the howto doc helped out great. mdadm-2.2 built with the patch and I was able to execute an assemble/scan with it. The array started and seems to be functioning fine. vapier@gentoo.org 2006-01-16 19:40:28 0000 added to cvs then as 2.2-r1, thanks for testing 77308 2006-01-16 17:32 0000 mdadm-2.2-update-segv.patch mdadm-2.2-update-segv.patch text/plain LS0tIEFzc2VtYmxlLmMub3JpZwkyMDA2LTAxLTE2IDIwOjMzOjAwLjAwMDAwMDAwMCAtMDUwMAor KysgQXNzZW1ibGUuYwkyMDA2LTAxLTE2IDIwOjMzOjE3LjAwMDAwMDAwMCAtMDUwMApAQCAtMjE5 LDcgKzIxOSw3IEBACiAJCX0KIAkJaWYgKGRmZCA+PSAwKSBjbG9zZShkZmQpOwogCi0JCWlmIChp ZGVudC0+dXVpZF9zZXQgJiYgKCF1cGRhdGUgJiYgc3RyY21wKHVwZGF0ZSwgInV1aWQiKSE9IDAp ICYmCisJCWlmIChpZGVudC0+dXVpZF9zZXQgJiYgdXBkYXRlICYmIHN0cmNtcCh1cGRhdGUsICJ1 dWlkIikhPSAwICYmCiAJCSAgICAoIXN1cGVyIHx8IHNhbWVfdXVpZChpbmZvLnV1aWQsIGlkZW50 LT51dWlkLCB0c3QtPnNzLT5zd2FwdXVpZCk9PTApKSB7CiAJCQlpZiAoKGluYXJndiAmJiB2ZXJi b3NlID49IDApIHx8IHZlcmJvc2UgPiAwKQogCQkJCWZwcmludGYoc3RkZXJyLCBOYW1lICI6ICVz IGhhcyB3cm9uZyB1dWlkLlxuIiwK
