Subject: Intel fakeraid working?
Date: Wed, 04 Apr 2012 20:56:48 -0400	[thread overview]
Message-ID: <4F7CEDD0.9080904@ubuntu.com> (raw)

I was trying to use mdadm to activate an intel fakeraid last night and mdadm insisted on activating it as read-only.  I could not get it to switch to read-wrte.  Today I came across this bug:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/972960

It seems that the kernel OOPSed here:

void md_write_start(struct mddev *mddev, struct bio *bi)
{
	int did_change = 0;
	if (bio_data_dir(bi) != WRITE)
		return;

	BUG_ON(mddev->ro == 1);

It appears this is because it wanted to update the metadata, but the array was read-only, so I thought this might be related to what I was seeing, and there is a bug that is preventing the array from correctly going read-write.

Is the Intel fakeraid support actually working yet, or still in development?
