xfs directory quota doesn't work

xfs directory quota doesn't work

[-- Attachment #1.1: Type: text/plain, Size: 1654 bytes --]

hi, everyone, I encounter a problem when using xfs

now I have two tasks and I wanna run them in different directory and limit
the directory’s size. I use xfs’s project quota to achieve this.

I follow the steps from here:
https://solidlinux.wordpress.com/2012/12/09/xfs-quota-managament/

here is detail of my two config files

/etc/projects:

11:/home/xiameng.xm/xfs_dir/task1
12:/home/xiameng.xm/xfs_dir/task2

/etc/projid:

task1:11
task2:12

and here is my step:

touch test_xfs
dd if=/dev/zero of=test_xfs bs=1000000 count=1
mkfs.xfs test_xfs

mkdir xfs_dir
mount test_xfs ./xfs_dir -o pquota,loop

xfs_quota -xc 'project –s task1' /home/xiameng.xm/xfs_dir
xfs_quota -xc 'project –s task2' /home/xiameng.xm/xfs_dir

xfs_quota -x -c 'limit -p bhard=2m task1' /home/xiameng.xm/xfs_dir
xfs_quota -x -c 'limit -p bhard=10m task2' /home/xiameng.xm/xfs_dir

here is the output of xfs_quota -x -c 'report /home/xiameng.xm/xfs_dir'

Project quota on /home/xiameng.xm/xfs_dir (/dev/loop1)
                               Blocks
Project ID       Used       Soft       Hard    Warn/Grace
---------- --------------------------------------------------
task1               0          0       2048     00 [--------]
task2               0          0      10240     00 [--------]

the question is no mater how large I create a file in ./xfs_dir/task1 or
./xfs_dir/task2, it success!

the quota limit doesn’t work!

Any help will be appreciated :)


ps: I also post my question here:

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.

I do create two subdirectory for project

and the error maybe caused by this step:
xfs_quota -x -c 'project –c task1' /home/xiameng.xm/xfs_dir

–c - 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 like an invalid character in the command here (and those
below). I probably didn't notice it before and just fixed up my local
commands...

>

... but this suggests it's not being interpreted as a command flag.
E.g., a command with the wrong character:

# xfs_quota -x -c 'project –c task1' /mnt
–c - no such project in /etc/projects or invalid project number
Checking project task1 (path /mnt/task1)...
/mnt/task1 - project identifier is not set (inode=0, tree=11)
/mnt/task1 - project inheritance flag is not set
Processed 1 (/etc/projects and cmdline) paths for project task1 with recursion depth infinite (-1).

vs. with the correct:

# xfs_quota -x -c 'project -c task1' /mnt
Checking project task1 (path /mnt/task1)...
/mnt/task1 - project identifier is not set (inode=0, tree=11)
/mnt/task1 - project inheritance flag is not set
Processed 1 (/etc/projects and cmdline) paths for project task1 with recursion depth infinite (-1).

All in all, you should see something like the following from the '-s'
command before this is expected to work:

# xfs_quota -xc 'project -s task1' /mnt
Setting up project task1 (path /mnt/task1)...
Processed 1 (/etc/projects and cmdline) paths for project task1 with recursion depth infinite (-1).

And for further verification, the project ID should be set on the
associated directory:

# xfs_io -c "lsproj" /mnt/task1
projid = 11
