I have two systems that I cvsuped & updated (kernels only) today.
RELENG_2_2
RELENG_3 (running softupdates (/ & /usr) /usr/home mounted via nfsv2
from the RELENG_2_2 system
Both systems are losing files/directories. On the Releng_3 system, I kept
writing a group of files to a directory and working with them.
I would then go do something else, and when I looked for the
files they were no longer there.
This happened several times.
Occasionally, I would do email on the RELENG_2_2 system. A few
minutes ago, I fired up Elm again, and it offered to create a 'Mail'
directory for me. My entire directory of saved mail has disappeared.
It appears that when files or directories are written, they are
accessible while in VM but they do NOT always get written to the disk!!!
(except when flushed by a re-boot).
On my test RELENG_3 system kernel is dated Feb 20 21:54
kernel.old Feb 20 10:20
more than one compile was done after the cvsup
I recompiled to turn off softupdates.
On my prod. RELENG_2_2-stable system kernel- Feb 20 10:42
kernel.old- Feb 13 00:10
one compile and install only today.
I would expect them to be the very close...
/usr/home is mounted on the RELENG_3 system via nfsv2.
********I don't do mail from the RELENG_3 system.
The only reason I recompiled the production system today, was
there was a change from luigi in both trees. I don't remember
exactly what it was. It is possible the RELENG_3-stable system
did the screwup though as it had access to the RELENG_2_2 /usr
via nfs.
I hope this info re symptoms helps.
Be careful!
Tom
P.S. I am now running kernel.GENERIC on the RELENG_3 system
& kernel.old on the RELENG_2_2
