2011-09-28mke2fs: set s_max_mnt_count to -1 by defaultTheodore Ts'o1-1/+5
If the enable_periodic_fsck option is false in /etc/mke2fs.conf (which is also the default), s_max_mnt_count needs to be set to -1, instead of 0. Kernels newer than 3.0 will interpret 0 to disable periodic checks, but older kernels will print a warning message on each mount, which will annoy users.

2011-09-25ext2fs: add multi-mount protection (INCOMPAT_MMP)Andreas Dilger1-0/+14
Multi-mount protection is feature that allows mke2fs, e2fsck, and others to detect if the filesystem is mounted on a remote node (on SAN disks) and avoid corrupting the filesystem. For e2fsprogs this means that it checks the MMP block to see if the filesystem is in use, and marks the filesystem busy while e2fsck is running on the system. This is useful on SAN disks that are shared between high-availability servers, or accessible by multiple nodes that aren't in HA pairs. MMP isn't intended to serve as a primary HA exclusion mechanism, but as a failsafe to protect against user, software, or hardware errors. There is no requirement that e2fsck updates the MMP block at regular intervals, but e2fsck does this occasionally to provide useful information to the sysadmin in case of a detected conflict. For the kernel (since Linux 3.0) MMP adds a "heartbeat" mechanism to periodically write to disk (every few seconds by default) to notify other nodes that the filesystem is still in use and unsafe to modify.

2011-09-18Shorten compile commands run by the build systemTheodore Ts'o1-0/+1
The DEFS line in MCONFIG had gotten so long that it exceeded 4k, and this was starting to cause some tools heartburn. It also made "make V=1" almost useless, since trying to following the individual commands run by make was lost in the noise of all of the defines. So fix this by putting the configure-generated defines in lib/config.h and the directory pathnames to lib/dirpaths.h. In addition, clean up some vestigal defines in configure.in and in the Makefiles to further shorten the cc command lines. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
2011-09-15e2fsprogs: create open() and stat() helpersLukas Czerner1-8/+2
In many places we are using #ifdef HAVE_OPEN64 to determine if we can use open64() but that's ugly. This commit creates two new helpers ext2fs_open_file() for open() and ext2fs_stat() for stat(). Also we need new typedef ext2fs_struct_stat for struct stat. Signed-off-by: Lukas Czerner <lczerner@redhat.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>
2011-09-13mke2fs: Use ext2fs_flush() only onceLukas Czerner1-3/+2
We are doing ext2fs_flush() twice right now at the end of the mke2fs. First by directly calling ext2fs_flush() which is intended to write superblock and fs accounting information. And then it is invoked again when we are calling ext2fs_close(), only this time, because the fs is not dirty, we are writing out only superblock. I think it is bad to call it twice because even when writing only super block it takes some time on bigger file systems and moreover ext2fs_close() can fail without any reasonable explanation for the user. Also ext2fs_flush() is printing out progress and it is confusing for the users. Fix all this by removing the ext2fs_flush() and leaving it all to ext2fs_close(). However we need to introduce new variables to store check interval and max mount count, because fs structure is freed on ext2fs_close() and we really want to print those information as the last info for the user.

This for RH bug #572935 - RFE: Misleading error message from mke2fs -J option If the journal device UUID is typo'd or otherwise not found, the error message looks like it's a usage() type of problem. It'd be helpful to explicitly say that the device requested could not be found.
