Hi Sun managers,
my original quesion was:
----- Begin Included Message -----
we have a critical problem with a Sparc 20/512 running
Solaris 2.4. The filesystem we use for non SUN Software
(named /usr/local) gets destroyed without any disk error
logged to /var/adm/messages. I should tell you, that we
export this file system to many clients via NFS/cachfs and
is placed on the second SCSI-interface.
What I see is, that the
root directory of the filesystem gets dirty.
says: cannot read .
Rebooting and running fsck results in asking for every inode
number (it starts with inode 2). Running fsck -y results
mostly in a clean (means empty!) filesystem.
Today the filesystem was not really empty,
but each directory under /usr/local
(and some more) was moved to lost+found.
Now some more special information:
I installed the following patches with
a public domain perl-script: fastpatch (!!!!!!):
101753-01 101933-01 102038-01
101829-01 101959-03 102044-01
101878-01 101979-03 102057-13
101879-01 102001-03 102057-14
101880-03 102002-01 102062-03
101902-01 102003-01 102066-04
101905-01 102007-01 102070-01
101907-02 102011-02 102079-01
101920-01 102020-02 102112-01
101921-04 102030-04 102137-01
101922-04 102035-01 102216-01
101923-03 102036-01 102292-01
101925-01 102037-01 102922-01
and last but not least 101945-27!
I believe that the problem occurs due to the
not correctly installed patches (fastpatch-script).
showrev -p or installpatch -p shows everything fine, but
reinstalling a client with printer problems has shown
that they have gone !!!
I tried to reinstall the patches with installpatch -u -d
but this does not work.
Any ideas or suggestions on the problem or the reinstalling
of the patches???
(Today I replaced the disk)

First let me thank all who have responded until now.
Most replies supposed that overlayed disk partitions caused
Format says that they do not overlapp.
At the moment I think about three possible reasons:
1.) The filesystem was export with write access and root-access to some
clients, administrated by me. If there would be a root-process running
an unlink() on the root-directory of that filesystem, the effect
would be the same.
There are two possible candidates for this unlink:
nfsfind is executind a find without -xdev option on /usr but
the mentioned FS is mounted under /usr/local
cachefs is used on the clients, because there is only less update
on /usr/local. It could be a cache coherency problem
I stopped root-access!
2.) Using the disk for the first time on SUN OS, the label was destroyed
due to power of during formatting. I reconstructed the label
with the informations I received from "format-current" in another
disk of the same type. Maybe something has gone wrong during the
new disk formatting. (I swapped the disk)
3.) I figured out a method for reinstalling the patches.
Deleting SUNW_PATCHID=.... from /var/sadm/pkg/..../pkginfo and
running installpatch works!
I have several misterious effects with Solaris 2.4 systems installed
by using fastpatch.
I do not use fastpatch anymore.
