 Hi James,

 thanks for your reply.

  XFS quotas should work just fine on LVM. To narrow down what is
 happening,
  can you please strace an xfs_quota command on the filesystem? Something
  like this should be sufficient:
 
  strace /usr/sbin/xfs_quota -c quota /mnt/tmp

 I should mention that quota does indeed work in general - I can not use
 more space than is allowed by the hard limit, and the usage and remaining
 free space is correctly displayed by 'quota' and 'quot'. The only thing
 which doesn't work with LVM is the reporting of free space via samba. But
 perhaps you can see something strange in this output:

[Samba] quota on xfs on lvm doesn't work(?)

2006-04-19 Thread Christoph Peus 

Hi,

I have a strange problem with user quotas enabled on a xfs filesystem 
and samba 3.0.21c: When a standard block device (e.g. /dev/sdc1) is used 
for the fs, quota works like expected:


/dev/sdc1 on /mnt/tmp type xfs (rw,usrquota)

output from level quota:10 debug:

[2006/04/19 14:38:48, 10] lib/sysquotas.c:sys_get_quota(394)
  sys_get_quota() uid(4004, 4004)

But when a logical volume is used for the fs, it doesn't work, and the 
clients windows explorer reports the size of the complete fs instead of 
the users quota:


/dev/export/lvol0 on /mnt/tmp type xfs (rw,usrquota)

What may be the cause for this Permission denied message? Permissions 
for /mnt/tmp are 777. Shouldn't samba operate independently of the 
filesystems underlying device?

Thanks for your support!
