greetings one and all. when attempting to install centos 6.8 to an i386 mid tower, during setup of hard disk partitions, selection is for /dev/sde. if continued, after reboot, error is displayed after 'welcome to centos'. lines read: Checking filesystem fsck.ext4: no such file or directory while trying to open /dev/sda3 /dev/sda3: The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -h 8193 <device> [FAILED] *** an error occurred during the file system check. *** Dropping you to a shell; the system will reboot *** when you leave the shell. *** Warning -- SELinux is active *** Disabling security enforcement for system recovery. *** Run 'setenforce 1' to reenable. Give root password for maintenance (or type Control-D to continue): entering 'e2fsck -h 8193 /dev/sda3' results with same e2fsck message as above. after reading article; http://www.cyberciti.biz/faq/recover-bad-superblock-from-corrupted-partition/ using command; dumpe2fs /dev/sda3 | grep superblock error message is; dumpe2fs: No such file or directory while trying to open /dev/sda3 Couldn't find valid filesystem superblock. if i enter command; dumpe2fs /dev/sde3 | grep superblock superblock info is shown. why is sde working and not sda? this system has previously held 6.8, but partitioning was off in cylinders so i decided to correct. purchased latest release of partedmagic, booted, created new partitioning by cylinders. under pmagic, when i enter command; dumpe2fs /dev/sda3 | grep superblock superblocks are shown. so, how do i correct what ever to install 6.8 to sda, not sde? any/all answers/suggestions greatly appreciated. tia. -- peace out.
