Title: problems checking a partition from Android (but not mounting!) Status in Enablement project for the Toshiba AC100 NetBook: New Status in e2fsprogs: New Status in “e2fsprogs” package in Ubuntu: New Bug description: I've installed Ubuntu 12.04 for Toshiba AC100, following the instructions at https://wiki.ubuntu.com/ARM/TEGRA/AC100 . Originally, there was Android on the computer. So, besides the partitions used for Ubuntu now, there are some partitions left untouched from Android. In the freshly installed system, they were mounted with a helper into /media/*, but then I wanted have permanent mountpoints for them (for saving stuff there), so I added them to /etc/fstab as ext3 (My names for the mountpoints may be not sensible and may not correspond to their actual purpose in Android, as for example listed in http://android.stackexchange.com/a/27852/13117; I haven't tried hard to determine the purpise of these partitions): # mount /dev/mmcblk0p12 on / type ext4 (rw,noatime,nodiratime,discard) proc on /proc type proc (rw,noexec,nosuid,nodev) sysfs on /sys type sysfs (rw,noexec,nosuid,nodev) none on /sys/kernel/debug type debugfs (rw) none on /sys/kernel/security type securityfs (rw) udev on /dev type devtmpfs (rw,mode=0755) devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620) tmpfs on /run type tmpfs (rw,noexec,nosuid,size=10%,mode=0755) none on /run/lock type tmpfs (rw,noexec,nosuid,nodev,size=5242880) none on /run/shm type tmpfs (rw,nosuid,nodev) /dev/mmcblk0p7 on /mnt/toshiba/recovery type ext3 (rw,nosuid,nodev,noatime,nodiratime) /dev/mmcblk0p10 on /mnt/toshiba/android type ext3 (rw,nosuid,nodev,noatime,nodiratime) binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,noexec,nosuid,nodev) gvfs-fuse-daemon on /home/imz/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=imz) /dev/mmcblk0p6 on /media/system type ext2 (rw,nosuid,nodev,uhelper=udisks) # If I added "discard" option in fstab for them, they wouldn't mount. (But this way they are mounted fine.) There appeared an error during boot: the check of these partitions fails. Let's have a look: what's wrong with the check? root@potka:~# umount /dev/mmcblk0p7 root@potka:~# fsck.ext3 /dev/mmcblk0p7 e2fsck 1.42 (29-Nov-2011) fsck.ext3: Superblock invalid, trying backup blocks... fsck.ext3: The ext2 superblock is corrupt при попытке открыть /dev/mmcblk0p7 The superблок could not be read or does not describe a correct ext2 ФС. If the устройство is valid and it really contains an ext2 ФС (and not swap or ufs or something else), then the superблок is corrupt, and you might try running e2fsck with an alternate superблок: e2fsck -b 8193 <устройство> root@potka:~# mount /dev/mmcblk0p7 root@potka:~# dmesg | tail [12523.855878] tegra_dvfs: rate 216000000 too high for dvfs on disp1 [14798.460340] tegra_dvfs: rate 216000000 too high for dvfs on disp1 [25522.814250] ec system event c5 04 01 00 02 00 ......
