Fsck.
I know what fsck is, and basically what it does, but I am no expert.
This week we had a raid5 box bust on us, the filesystem on raid5 partition was recovered, and I did an fsck in read only mode to get data on the partition. This was the output.
/dev/etherd/e1.0 contains a file system with errors, check forced.
Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts
Pass 5: Checking group summary information
/dev/etherd/e1.0: 3235947/4960256 files (5.6% non-contiguous), 845580732/1269811919 blocks
Now like I said, I am not an expert, so I was hoping someone could explain the returned message in more descriptive terms, so I know what it's telling me. I understand the "Pass" references and the initial line. I don't understand what the final line is telling me other than 5.6% is non contiguous. I know contiguous means next to each other so is it saying 5.6% of blocks aren't next to each other? Why is that important? I'd love to know what this truly means.
