[gfs2-utils] 01/02: mkfs.gfs2: Scale down journal size for smaller
devices
by git repository hosting
This is an automated email from the git hooks/post-receive script.
andyp pushed a commit to branch RHEL7
in repository gfs2-utils.
commit cc079a4d907eedd24c69ab2a88e9e0fcdef58a5d
Author: Andrew Price <anprice(a)redhat.com>
Date: Mon Feb 12 19:27:48 2018 +0000
mkfs.gfs2: Scale down journal size for smaller devices
Currently the default behaviour when the journal size is not specified
is to use a default size of 128M, which means that mkfs.gfs2 can run out
of space while writing to a small device. The hard default also means
that some xfstests fail with gfs2 as they try to create small file
systems.
This patch addresses these problems by setting sensible default journal
sizes depending on the size of the file system. Journal sizes specified
by the user are limited to half of the fs. As the minimum journal size
is 8MB that means we effectively get a hard minimum file system size of
16MB (per journal).
Resolves: rhbz#1498068

scripts: Install gfs2_withdraw_helper into $libexecdir
This is a more appropriate location as the helper script isn't meant to
be run by users. It also means that various checkers will stop
complaining that there is no man page for this script.
The 82-gfs2-withdraw.rules udev hook is now generated from the .in file
so that $libexecdir can be substituted into it. The path can be set at
configure time.
