b2cd1ce8ee Allow enabling soft updates (with -U) on a new filesystem.
[I first added this functionality, and thought to check prior art.  Seeing
OpenBSD had already done this, I changed my addition to reduce the diffs
between the two and went with their option letter.]

094ab93715 The common wisdom is to use the largest number of cylinders per group.
So bump the default from `16' to `22', which is the largest value allowed
with the current default block size.  This change increases the the
group size from 32MB/g to 44MB/g on a 4GB SCSI disk.

9884911506 mdoc(7) police: fixed broken references. 2001-01-16 11:52:00 +00:00

f55ff3f3ef The ffs superblock includes a 128-byte region for use by temporary
in-core pointers to summary information. An array in this region
(fs_csp) could overflow on filesystems with a very large number of
cylinder groups (~16000 on i386 with 8k blocks). When this happens,
other fields in the superblock get corrupted, and fsck refuses to
check the filesystem.

Solve this problem by replacing the fs_csp array in 'struct fs'
with a single pointer, and add padding to keep the length of the
128-byte region fixed. Update the kernel and userland utilities
to use just this single pointer.

With this change, the kernel no longer makes use of the superblock
fields 'fs_csshift' and 'fs_csmask'. Add a comment to newfs/mkfs.c
to indicate that these fields must be calculated for compatibility
with older kernels.

45c29d5cda The write combining code in revision 1.30 needs a few additional
touch ups.  The cache needs to be flushed against block
reads, and a final flush at process termination to force the
backup superblocks to disk.

I believe this will allow 'make release' to complete.

3927beeda1 Implement simple write combining for newfs - this is particularly useful
for large scsi disks with WCE = 0.  This yields around a 7 times speedup
on elapsed newfs time on test disks here.  64k clusters seems to be the
sweet spot for scsi disks using our present drivers.

the mount is completely active, causing the next few commands attempting

    to wait for the mount point st_dev to change before returning, indicating
    that the mount has gone active.

7b955a8e5d Don't rewrite the disk label. The type field is already set correctly
and we don't use the frags info, so why bother?  More to the point, it
seems to result in an EXDEV error when the label is written out and we
lose because of it (don't know why though).  This is a work-around and
is marked as such.

     -v      Specify that the partition does not contain any slices, and that
             newfs should treat the whole partition as the file system.  This
             option is useful for synthetic disks such as ccd and vinum.

in the label to find alternate superblocks when the main superblock

label.

90e05a748a Don't create superblocks with size larger than SBSIZE (8192). The
size was rounded up to a multiple of the fragment size, but this
gave invalid file systems when the fragment size was > SBSIZE (fsck
aborts early on them).  Now a fragment size of 32768 seems to work
(too-simple tests with fsck and iozone worked).

079709dc3a Some tweaks to get this to cope with ELF where the address space starts
higher up in memory (0x0800000 upwards) rather than near zero (0x1000
for our qmagic a.out format).  The method that mount_mfs uses to allocate
the memory within data size rlimits for the ram disk is entirely too much
of a kludge for my liking.  I mean, if it's run as root, surely it makes
sense to just raise the resource limits to infinity or something, and if
it's a non-root user mount (do these work? with mfs?) it could just fail
if it's outside limits.

28596d2346 Removed "hack to prevent overflow of a 32bit block number". Lite2 has a
better hack in ffs_vfsops.c.  The hack here restricted the maximum file
size to 2^39 bytes (512GB).  fs_bsize * 2^31 - 1 (16TB for the default
blocksize of 8K) would have been better.  There is no good way to remove
this limit on old BSD4.4 file systems.
