I've had a sid/unstable system with four raid1 / mdadm partitions running for about 4 years now... Recently, upon boot-up, three of those four partitions come up as "auto-read-only" in /proc/mdstat for example: md3 : active (auto-read-only) raid1 sda4[0] sdb4[1] 280631360 blocks [2/2] [UU]
this device DOESN'T appear in /dev/md3 however: md2 : active raid1 sda3[0] sdb3[1] 9767424 blocks [2/2] [UU] isn't auto-read-only, and does appear as /dev/md2... I'd like to reset the "auto-read-only" on /dev/md3, but /dev/md3 doesn't exist. Sometimes I've seen it show up as /dev/.tmp.md3, but it isn't consistent... where does it go? -Derek
