- Due to a bug in the `mkdev fs' program, filesystems mounted below
- the root directory are labeled wrong. For example, if you mount
- a device `/dev/news' onto directory `/usr/spool/news', then you
- ! will get a warning message when going into multi-user mode. This
- ! would not happen if the mount point for `/dev/news' was a directory
- ! called `/news'.
-
- This message is merely an annoyance and will not hamper system
- operation. To eliminate the warning, relabel the filesystem with
- the last component of the mount directory. For the above example,
- ! you may do this by running the command:
-
- - # `news' is the basename of mount dir `/usr/spool/news'
- fsname -s news /dev/news
-
-
- ! QC5. Is disk fragmentation curable?
-
- Not easily. However, the steps to slow down fragmentation are
- pretty simple.

- the root directory are labeled wrong. For example, if you mount
- a device `/dev/news' onto directory `/usr/spool/news', then you
- ! will get a warning message when going into multi-user mode. That's
- ! because `mkdev fs' labels the filesystem with the first component
- ! in the pathname (`usr' in this example) when it really should be
- ! the last component in the pathname (`news' in this example).
-
- This message is merely an annoyance and will not hamper system

- ! QC5. `POSSIBLE FILE SIZE ERROR' when running `fsck'.
-
- + If `fsck' says `POSSIBLE FILE SIZE ERROR I=nnnn' don't panic. It
- + almost always means `fsck' found a `sparse file', not a true
- + filesystem error. A sparse file has holes in it. They are created
- + when a program skips over sections of a file it is writing. The
- + XENIX filesystem fills in those sections with zeros. The XENIX
- + filesystem doesn't even both allocating disk blocks for the sections
- + full of zeros, thus creating a sparse file. The complaint occurs
- + because `fsck' calculates the number of disk blocks needed to
- + store the file, counts up the number of disk blocks actually used
- + by the file, and complains that the two don't match.
- +
- + When you get a file size error from `fsck' you should note both
- + the `I=nnnn' inode number logged in the message and the filesystem
- + which was being checked. You can see what the file is by running
- + the following command:
- +
- + ncheck -i <nnnn> <fsname>
- +
- + where <nnnn> is the number logged in the error message and <fsname>
- + is the pathname of the filesystem device, e.g. `/dev/u'. Chances
- + are the file will either be a dbm(S) database file (in which case
- + ignore the complaint, it's expected) or a `core' dump (in which
- + case delete the `core' file).
- +
- +
- + QC6. Is disk fragmentation curable?
- +
- Not easily. However, the steps to slow down fragmentation are
- pretty simple.
