Re: xfs directory quota doesn't work

[Simon Xia <simonxiaomg@xxxxxxxxx>]

I do create two subdirectory for project

and the error maybe caused by this step:

xfs_quota -x -c 'project âc task1' /home/xiameng.xm/xfs_dir

âc - no such project in /etc/projects

Checking project task1 (path /home/xiameng.xm/xfs_dir/task1)...

/home/xiameng.xm/xfs_dir/task1 - project identifier is not set (inode=0, tree=11)

/home/xiameng.xm/xfs_dir/task1 - project inheritance flag is not set

Processed 1 /etc/projects paths for project task1

I'm a little confused about the output message, cause everything is ok in config file

That looks small, I can't even mkfs a file that small. I ran through
this using 'bs=1M count=100.'

I don't see where you've created the directories yet..? I get the
following:

# xfs_quota -xc 'project -s task1' /mnt/
xfs_quota: cannot find mount point for path `/mnt/task1': No such file or directory

... until I create the task1/task2 directories. This is required because
the project quota command has to set the project id on the directory
inode. It won't work if the directory is created after this point,
regardless of whether the quota limit is specified.

Once I create those directories and run the project command, everything
seems to work. I can write up to 2MB to task1 and 10MB to task2.
