I am running VMware Server 2.0 but see the same results with 
VMware Server 1.0.  The virtual machines are copies that I 
made by transferring the vmware files for it from another server. 
As far as I know it did not have any fsck problems on that machine 
but I don't have access to it any more.  I have noticed that there 
are a lot of failures (corrupted files) when moving VMware appliances with the 
use of USB memory sticks so I do test them right on the memory 
stick before I disconnect from the PC.

All the host OSs are Windows XP Professional using IDE ATA drives, current
hardware is an HP dx2450 AMD Phenom. but I saw the same errors on an Acer.

The files systems are:

# Device                Mountpoint      FStype  Options         Dump    Pass#
/dev/ad0s1b             none            swap    sw              0       0
/dev/ad0s1a             /               ufs     rw              1       1
/dev/ad0s1e             /usr            ufs     rw              2       2
/dev/ad0s1d             /var            ufs     rw              2       2
/dev/acd0               /cdrom          cd9660  ro,noauto       0       0

Here is a bit from fsck of /var

hueysan_vm: {10} fsck /var
** /dev/ad0s1d (NO WRITE)
** Last Mounted on /var
** Phase 1 - Check Blocks and Sizes
** Phase 2 - Check Pathnames
** Phase 3 - Check Connectivity
** Phase 4 - Check Reference Counts
UNREF FILE  I=190413  OWNER=root MODE=100644
SIZE=235 MTIME=Dec 27 12:23 2008
RECONNECT? no


CLEAR? no
...

I get about a dozen similar UNREF errors.


I am only worried about the errors if they might cause a problem 
with the use of the virtual server as a development server.  I have 
installed and have running apache, mysql, sendmail, samba, 
rsync, etc and they all seem to work fine.  I am planning on 
distributing copies of the virtual server to some others who are 
working on a project with me so I really only need to be 
fairly sure that no hidden gotchas are going to plague 
our efforts.  Having the virtual server setup is a BIG plus 
when collaborating with people who only have Windows 
PCs, before I had a central FreeBSD server for testing 
etc but that is so much slower then have a local development 
server.  Being able to just send off a memory stick with the 
VMserver and instructions is fantastic.


Thanks to all,
Charlie Reese
