| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using -U option you can change the UUID for fs, however it will not work for journal device, since it have a copy of this UUID inside jsb (i.e. journal super block).

* filefrag: fix block size valueRakesh Pandit2014-07-271-10/+11
| | | | | | | | | | | | | | | | | | ioctl(FIGETBSZ) was used to get block size earlier but 2508eaa7 (filefrag: improvements to filefrag FIEMAP handling) moved to fstatfs f_bsize which doesn't work well for many files systems. Block size returned using fstatfs isn't block size but "optimal transfer block size" as per man page. Even stat st_blksize is "preferred I/O block size" and in may file systems it may even vary from file to file (POSIX). This patch changes filefrag to use FIGETBSZ preferentially over f_bsize.

* Fix 32/64-bit overflow when multiplying by blocks/clusters per groupTheodore Ts'o2014-07-261-1/+1
| | | | | | | | | | | | | | | | | There are a number of places where we need convert groups to blocks or clusters by multiply the groups by blocks/clusters per group. Unfortunately, both quantities are 32-bit, but the result needs to be 64-bit, and very often the cast to 64-bit gets lost. Fix this by adding new macros, EXT2_GROUPS_TO_BLOCKS() and EXT2_GROUPS_TO_CLUSTERS().

* e4defrag: backwards-allocated files should be defragmented tooDarrick J. Wong2014-07-221-1/+3
| | | | | | | | | | | | | | | | | | | | Currently, e4defrag avoids increasing file fragmentation by comparing the number of runs of physical extents of both the original and the donor files. Unfortunately, there is a bug in the routine that counts physical extents, since it doesn't look at the logical block offsets of the extents. Therefore, a file whose blocks were allocated in reverse order will be seen as only having one big physical extent, and therefore will not be defragmented. Fix the counting routine to consider logical extent offset so that we defragment backwards-allocated files. This could be problematic if we ever gain the ability to lay out logically sparse extents in a physically contiguous manner, but presumably one wouldn't call defrag on such a file.

* e2fsprogs: introduce ext2fs_close_free() helperLukas Czerner2014-07-057-15/+15
| | | | | | | | | | | | | | | | | | | | | | | | | Currently there are many uses of ext2fs_close() which might be wrong. First of all ext2fs_close() does not set the ext2_filsys pointer to NULL so the caller is responsible for clearing it, however there are some cases there we do not do it. Second of all very small number of users of ext2fs_close() actually check the return value. If there is a problem in ext2fs_close() it will not even free the ext2_filsys structure, but majority of users expect it to do so. To fix both problems this commit introduces a new helper ext2fs_close_free() which will not only check for the return value and free the ext2_filsys structure if the call to ext2fs_close2() failed, but it will also set the ext2_filsys pointer to NULL. Replace every use of ext2fs_close() in e2fsprogs tools with ext2fs_close_free() - there is no real reason to keep using ext2fs_close().

* mke2fs: print a message when creating a regular fileTheodore Ts'o2014-05-053-6/+12
| | | | | | | | | | We've added the ability to automatically recreate a file if it doesn't exist prior to creating the file system, since this is often used (for example) when managing file system images for use in virtual machines. We should at least notify the user that this is going on to avoid surprises in the case of misspelled device/file names. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
* e2fsprogs/filefrag: print shared extent flagMark Fasheh2014-05-041-0/+2
| | | | | | | | Filefrag doesn't catch and print the shared extent flag. Add this for users of filefrag on file systems with shared extents (such as btrfs). Signed-off-by: Mark Fasheh <mfasheh@suse.de> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
* mke2fs: only print the low-level file system stats in verbose modeTheodore Ts'o2014-05-041-0/+11
| | | | | | Also print the file system UUID if it is non-NULL. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
* mke2fs: check for pre-existing file systemTheodore Ts'o2014-05-043-3/+36
| | | | | | | | Warn the system administrator if there is an existing file system on the block device, and give the administrator an opportunity to abort the mkfs operation. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
* mke2fs: add an option in mke2fs.conf to proceed after a delayTheodore Ts'o2014-05-045-10/+52
| | | | | | | | | | If mke2fs needs to ask the user for permission, and the user doesn't type anything the specified delay in the /etc/mke2fs.conf file, proceed as if the user had said yes. The default is to do what we currently do, which is to wait until the user answers the question one way or the other. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
* mke2fs: create a regular file if necessaryTheodore Ts'o2014-04-263-5/+19
| | | | | | | This is useful when creating a filesystem for use with a VM, for example. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
* mke2fs: don't complain if the regular file is too smallTheodore Ts'o2014-04-261-3/+3
| | | | | | | | | | Don't ask the user if it's OK that a regular file is smaller than the requested size. This test only makes sense if we are creating the file system on a block device. This allow users to not need to manually answer the "proceed?" question when creating a file system backed by a simple file. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
* mke2fs, tune2fs: call proceed_question() from check_plausibility()'s callerTheodore Ts'o2014-04-264-12/+18
| | | | | | | | Move the call to proceed_question() from check_plausibility() to its caller. This allows more fine grained control by mke2fs about when it might want to call check_plausibility(). Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
* mke2fs: don't ask the proceed question using a regular fileTheodore Ts'o2014-04-264-10/+21
| | | | | | | | | | | | Very often people are creating file systems using regular files, so we shouldn't ask the user to confirm using the proceed question. Otherwise it encourages users to use the -F flag, which is a bad thing. We do need to continue to check if the external journal device is a block device.
