Subject: Extend BTRFS_IOC_DEVICES_READY for degraded RAID
Date: Mon, 05 Jan 2015 10:46:46 +0100 [thread overview]
Message-ID: <54AA5D86.1000503@redhat.com> (raw)
We have BTRFS_IOC_DEVICES_READY to report, if all devices are present, so that
a udev rule can report ID_BTRFS_READY and SYSTEMD_READY.
I think we need a third state here for a degraded RAID, which can be mounted,
but should only after a certain timeout/kernel command line params.
We also have to rethink how to handle the udev DB update for the change of the
state. incomplete -> degraded -> complete
