xfs_quota free

[Dan-206]

Hi,

Some time ago I needed to determine the free space on a real time
device.  Nate indicated to use xfs_quota free.  I've read the man pages
and tried many iterations of this command but I cannot get any results.

One potential problem is I'm uncertain of the folder or device to point
the command at.  My filesystem is mounted to /mnt, the rtdev is /dev/md0
and meta data is on /dev/sdb.  Basically it boils down to xfs_quota -c
'free -r -h'  /mnt I think but I get the following error:

XFS_IOC_FSGEOMETRY_V1: Invalid argument

How do you use this?

Thanks,

Dan

A similar issue has been reported in http://lists.xensource.com/archives/html/xen-users/2007-10/msg00577.html

Which kernel are you running?

Do you happen to have 32-bit userspace on a 64-bit kernel?

Could be an ioctl translation problem if so.

Otherwise maybe a quota-savvy person knows ;)

Hi,

I'm running 2.6.22 on CentOS 4.4.  I don't have the version of XFS tools on me right now.  I do believe I got the right package.  Would the 32 bit binaries format and manipulate he other features of XFS properly and only fail on free blocks?

thanks!!

Dan

The post I mentioned was just one of a few search results. It said that
this would be fixed in "recent kernels". The post is from 10/2007, where
kernel 2.6.23 was "current", so the statement is rather vague :-\

Please see Eric's post; what system (kernel, userland) are you on?
