Unexpected Inconsistency Run Fsck Manually

EXT4-fs error count since last fsck:1 give root password for maintenance

This means your ODA Guess VM has fsck error and filesystem may be corrupt.

Type root password in the ILOM or Guess VM VNC. Then check mount count like following.

dumpe2fs /dev/xvda2 | egrep -i 'mount count|check' | more

Then reset that mount count like following.

tune2fs -c 0 -i 0 /dev/xvda2

Now Run Fsck Manually like following. You should change device names  ( /dev/xvda1,2 etc. ) according to your environment.

fsck /dev/xvda1
fsck /dev/xvda2
fsck /dev/xvdb1

Now Run Fsck.ext4 Manually like following. You should change device names  ( /dev/xvda1,2 etc. ) according to your environment.
