Hi, below comes a new version of the series of patches implementing quota support for ocfs2-tools. I've fixed the calls of ocfs2_malloc_blocks() which were given number of bytes instead of number of blocks. Besides that the series should be the same. Honza

Hi, this is the next version of quota support for quota tools. I've addressed all the comments of Tao, Joel and others. Sparse feature disabling also correctly updates quota information now and the patch is merged into the tunefs support patch. Honza

Add online resize in tunefs.ocfs2 so that user can increase the volume when it is mounted.

Hi, I'm sending a series of patches implementing quota support into ocfs2-tools. It's the same as the original huge patch I've sent but now it's split as Joel asked. I've also realized that when disabling SPARSE feature, we should update quota information. That piece of code is missing, I'll implement it soon. Comments welcome. Honza

Hi, I'm sending a patch for proper quota support when disabling sparse feature. The second patch fixes a minor problem in tunefs.ocfs2 when disabling the sparse feature. In a few days I plan to resend the whole "quota support" series with all the changes people request included... Honza

Now it's a good time to introduce the new tool 'o2info' since kernel part of OCFS2_IOC_INFO ioctl has been pulld upstream by linus. The following 6 patches have already got sunil's SOBs, and now they're trying to attract more reviewers before it goes to central repo with a modification of getting manual pages being introduced.

There is a small test provided. I tested this a lot more locally and it seems pretty robust. Rich.

Hello, Recently, I am coding a program about read and write control. And there are some questions confusing me. 1. In info libext2fs: Function: errcode_t ext2fs_get_blocks (ext2_filsys FS, ext2_ino_t INO, blk_t *BLOCKS) Returns an array of blocks corresponding to the direct, indirect, doubly indirect, and triply indirect blocks as stored in the inode structure. So I wrote some codes like following: blk_t target_blks[EXT_N_BLOCKS]; retval = ext2fs_...

Hi, to ease debugging issues with appliances (e.g. when used in libguestfs), using --include-packagelist will add a file containing the list of all the packages used.

Turns out Japanese trains are good for coding! In supermin we have a bunch of code to create the libguestfs appliance. It creates it directly using libext2fs (part of e2fsprogs). We can use the same technique to create ext2 virtual disks in nbdkit, which is what this new plugin does. Why a new plugin instead of modifying the floppy plugin? See the 4/4 commit message for an explanation. The

Another interesting thing you can do with this plugin: https://rwmj.wordpress.com/2019/02/19/nbdkit-linuxdisk-plugin/ v2: - Fix inconsistent tab/space. - All 3 plugins now contain a block of text pointing to the other 2 plugins. - TMDIR -> TMPDIR - Unlink the temporary file and other cleanups along error paths. - fclose -> pclose, and check the return value for errors. -
