site_archiver@lists.apple.com Delivered-To: darwin-kernel@lists.apple.com -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 We have a block storage driver kext that can we would like to be able to change from read-write to read-only dynamically. I've worked out how to change the driver to read-only and the underlying IOMedia object. But the read-only change doesn't propagate any further to the file system IOMedia objects or the file system. If the underlying media is changed to read-only then an error is returned by the file system. However, if the media is then changed back to read-write, the file system continues to display an error. I'm fine with the error, the problem in this case is getting the file system to try again so that it is successful. How can I go about updating the file system so that it is aware that the media has changed to read-only and then later back to read-write? Thanks for any tips, ...Duane -----BEGIN PGP SIGNATURE----- Version: PGP Desktop 9.10.0 (Build 500) Charset: US-ASCII wsBVAwUBS3SKo0rg9acQ4r2CAQj5DwgA9zRRyL5bb8B2HkBs0bH0BhJwzc3LUukj sWMKIkM2ZMw80gED7ZT1ZPckxVReSDAaEKfe3usM8G3R1KMmq+CQansvm6y6J5lu R6r4sDb66POoR2l3xgQ8+iwo/Wl/oCCr/kNQC2DcgmQnD3X41+im3P0YV/NTafZB loaitvKGu95nXzVs8eEAkV0oz36Cxi0DhiPWBAzcA/A67sWot0NvaSo3Q0xec49M ztfJamVtNhOYrT2FknHXxUWKoiEDJcg+RNbdoRQa3W/JuOeiEL/X2mL1BA4ZuFYE SsNqk5aJixcVtcZ1w7KSGfR69oAu6vzOlrRErfxKrHUUaax9mcdc2g== =g48r -----END PGP SIGNATURE----- _______________________________________________ Do not post admin requests to the list.
