Description Mike Thomas 2004-12-19 07:52:30 UTC
I am sharing an NFS mount (version 3, proto tcp) from a linux box via a solaris
2.6 server running samba 3.0.10 (was running 3.0.2a, upgraded to see if it fixed
this problem).

Whenever a computer mounts this partition, it always shows a partition size of
1.4G with 1.4G used (there is about 29 gig used on this partition, its actual
size is 527G) with 0% free space available. This causes no behavior problems
excecpt on Mac OSX clients where when trying to write a new file via a finder
window (copying, etc) will fail with the result of 'not enough free space
available' as Mac OS X performs a freespace check before attempting to write the
file. It however works just fine via the command line, and on all other unixish
clients that access it.

What I've done to try to resolve this. Via a suggestion and using the smb.conf I
have setup a dfree command in the conf with this smb.conf option

mozart lib# cat smb.conf |grep dfree
        dfree command           =       /usr/sbin/dfree

the output of dfree is as follows:

mozart lib# dfree
551681064 516468320 4096

source of dfree is:

mozart lib# cat /usr/sbin/dfree

df -k $1 | tail -1 | awk '{print $2" "$4 " " 4096}'

The df -k output is:

mozart lib# df -k /export/web
Filesystem            kbytes    used   avail capacity  Mounted on
asgard:/CEMS/web     551681064 35212744 516468320     7%    /export/web

The corresponding output of df on a client that mounted the share in question:

//mozart/unix_web     1.4G  1.4G     0 100% /mnt/temp

here's some output from the log.smbd showing that its using the dfree output

[2004/12/19 07:26:05, 3] smbd/dfree.c:disk_free(88)
  disk_free: Running command /usr/sbin/dfree .
[2004/12/19 07:26:05, 3] smbd/dfree.c:disk_free(94)
  Read input from dfree, "551681064 516468272 4096"
[2004/12/19 07:26:05, 3] smbd/dfree.c:disk_free(109)
  Parsed output of dfree, dsize=551681064, dfree=516468272, bsize=4096

I have also tried experimenting with the block size = line in smb.conf to no avail.

If you need anything more from me in terms of debug output, let me know, and
I'll get whatever you need.
