I am using lvm2 with the following logical volume:

--- Logical volume ---

  LV Name                /dev/nwlsd_vg/nwlsd_lv
  VG Name                nwlsd_vg
  LV UUID                jKXS7Q-2Bda-JpVG-Ba4I-Ocfr-6UyO-182Mek
  LV Write Access        read/write
  LV Status              available
  # open                 1
  LV Size                55.91 GB
  Current LE             14312
  Segments               2
  Allocation             next free (default)
  Read ahead sectors     0
  Block device           254:0

I am trying to get quota's working on the system. The quotas themselves are working, however, standard users cannot issue the quota command to inspect their own specific information:

$ quota
quota: Can't stat() mounted device /dev/nwlsd_vg/nwlsd_lv: Permission
denied
Disk quotas for user mellofone (uid 1000): none

However, it does work for root:

$ quota mellofone
Disk quotas for user mellofone (uid 1000): 
     Filesystem  blocks   quota   limit   grace   files   quota   limit   grace
/dev/nwlsd_vg/nwlsd_lv
                19364268*      0  100000            2019       0       0    0

This setup works on other volumes that do not use lvm. Any ideas what I screwed up? Just as an FYI:

$ lvm version
  LVM version:     2.00.09 (2004-03-31)
  Library version: 1.00.08-ioctl (2004-02-27)
  Driver version:  4.1.0

Thanks.

chgrp disk /dev/mapper/*
chmod g=rw /dev/mapper/*

We need to fix that in dmlib (if not already done ;)

The problem seems to be the volume group directory which is set 700 here. Changing it to 755 fixes the problem for me, even if the device nodes in /dev/mapper themselves are still 600.

Ah ha! Confirmed. It works here now as well, without touching /dev/mapper. I should have checked that.

Thanks for the quick responses!
