Hi all, The maintainers have been besieged by a /lot/ of complaints recently from people who format tiny filesystems and growfs them into huge ones, and others who format small filesystems. We don't really want people to have filesystems with no backup superblocks, and there are myriad performance problems on modern-day filesystems when the log gets too small. Empirical evidence shows that increasing the minimum log size to 64MB eliminates most of the stalling problems and other unwanted behaviors, so this series makes that change and then disables creation of small filesystems, which are defined as single-AGs fses, fses with a log size smaller than 64MB, and fses smaller than 300MB. If you're going to start using this mess, you probably ought to just pull from my git trees, which are linked below. This is an extraordinary way to destroy everything. Enjoy! Comments and questions are, as always, welcome. --D xfsprogs git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfsprogs-dev.git/log/?h=mkfs-forbid-tiny-fs --- mkfs/xfs_mkfs.c | 192 +++++++++++++++++++++++++++++++++++++++++++------------ 1 file changed, 151 insertions(+), 41 deletions(-)
