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? -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBAgAGBQJPfO3QAAoJEJrBOlT6nu75IS4H/0nerXBIW6wnYrmZPbWZH+sr kVTVPDAqLCvbUATicLdwsJULWwqJmsyWnXTwnm7Ssug2phmcnK8cDFzNiLY/Q3ez A0YdMmVog74viMSfZTLVfeiPYnccuTYLeH/U3glJVJ2ISyoFQi0mH6Kd/1eEO153 4XazWr7pj/QFeBsPnYuVlojvlsHR6QwdjU3aAsObdCxWdITrnJLLRYC9S4cgqS9m Mdh1A4dbzeyj5SrNDAX1McQD+SQDnrPR6r17Tftr9eMcLCp6mzaxYkUu+GE1r8jr 9DRqGqe0sAdNjOn4cFMRZVOaHxMjGUXxxn8tuDNS2/p99P6kdCvQO280PFHByog= =H98J -----END PGP SIGNATURE-----
