** Description changed: Ubuntu kernels silently wrap access to disk locations above 2 TB back around to zero. This can easily be reproduced using lvm to create a thin provisioned virtual disk: lvcreate -s -n thin -L 1g --virtualsize 3t vg0 mke2fs -t ext4 -E lazy_itable_init /dev/vg0/thin e2fsck -f /dev/vg0/thin Fsck will find errors in the bitmap because it is actually reading the superblock instead of the allocation bitmap situated just after the 2 tb mark. + + + --- + AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.21. + Architecture: amd64 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC0: psusi 1874 F.... pulseaudio + CRDA: Error: [Errno 2] No such file or directory + Card0.Amixer.info: + Card hw:0 'NVidia'/'HDA NVidia at 0xfe024000 irq 20' + Mixer name : 'Realtek ALC888' + Components : 'HDA:10ec0888,1565820c,00100001' + Controls : 37 + Simple ctrls : 20 + Card1.Amixer.info: + Card hw:1 'HDMI'/'HDA ATI HDMI at 0xfd9fc000 irq 16' + Mixer name : 'ATI R6xx HDMI' + Components : 'HDA:1002aa01,00aa0100,00100100' + Controls : 4 + Simple ctrls : 1 + Card1.Amixer.values: + Simple mixer control 'IEC958',0 + Capabilities: pswitch pswitch-joined penum + Playback channels: Mono + Mono: Playback [off] + DistroRelease: Ubuntu 10.04 + InstallationMedia: Ubuntu 9.10 "Karmic Koala" - Release amd64 (20091027) + IwConfig: + lo no wireless extensions. + + eth0 no wireless extensions. + Lsusb: + Bus 002 Device 003: ID 045e:0039 Microsoft Corp.
