Description of problem: In our setup an NFS server exports directories with user quotas. A second Samba server mounts the directories and shares them. When writing to such a share on Windows XP when the hard limit of the quota is reached, the files are truncated or filled with garbage without any error message. Version-Release number of selected component (if applicable): Linux fire 2.6.9-42.ELsmp #1 SMP Wed Jul 12 23:27:17 EDT 2006 i686 i686 i386 GNU/Linux samba-common-3.0.10-1.4E.9 samba-3.0.10-1.4E.9 nfs-utils-lib-1.0.6-3 nfs-utils-1.0.6-70.EL4 How reproducible: NFS export a partition with user quotas on one server, mount it on another server and share the mounted NFS share to a Windows XP client. Set a quota for a user and map a network drive to the share as the user with the quota. Attempt to copy more data to the share than the user quota's hard block limit. Steps to Reproduce: 1. On the NFS server (here fire) prepare a partition /local with user quotas turned on and do: fire:~# mount | grep local /dev/sda8 on /local type ext3 (rw,usrquota) fire:~# df /local Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda8 136163944 119700 129127460 1% /local fire:~# quota walteste Disk quotas for user walteste (uid 50515): none fire:~# setquota -u walteste 10000 20000 1000 2000 /local fire:~# quota walteste Disk quotas for user walteste (uid 50515): Filesystem blocks quota limit grace files quota limit grace /dev/sda8 8764 10000 20000 104 1000 2000 fire:~# exportfs -o async,rw ice:/local 2. On the Samba server (here ice) use the factory smb.conf supplied with RHEL AS4 and do: ice:/# mkdir /remote ice:~# mount fire:/local /remote ice:~# df /remote Filesystem 1K-blocks Used Available Use% Mounted on fire:/local 136163968 119712 129127488 1% /remote ice:/etc/samba# cat >>smb.conf [remote] path = /remote browseable = no writable = yes comment = Remote with quota <CTRL-D> ice:/remote# service smb restart Shutting down SMB services: [ OK ] Shutting down NMB services: [ OK ] Starting SMB services: [ OK ] Starting NMB services: [ OK ] 3. Map a netwoork drive to '\\ice\remote' on a fully updated Windows XP Professional client and try to copy 50MB data to the share Actual results: The files are all copied and the correct sizes are displayed in the file properties dialog in windows. The files written after the users hard block limit was reached on the NFS server contain garbage. Expected results: An error message should be displayed when the quota is reached. Ideally this message should indicate that the problem is related to the quota. A simple I/O error od disk full message would also help. Additional info: Using 'strict allocate = YES' in the smb.conf will truncate files to the size that could effectively been written to the NFS server but does not display an error messager either. Enabling strict allocation is the documented way to get the error messages to display. This does not seem to be effective for the Samba shipping with RHEL.
Resharing of NFS, especially for writing, is not supported.
