Do you have any idea what can have caused the following: (I have only seen
it once - yet)
Situation:
Client 1: alphastation running DU 4.0b. All local filesystems are AdvFS.
separate /usr and /var. Automounts /usr/var/spool/mail, user's homedirs
etc.
Server 1: DECstation 5000/200 running Ultrix 4.2A. Serves
/usr/var/spool/mail (NFSv2).
Server 2: Alphaserver running DU 4.0b. Serves home directories and
various software (NFSv3).
Other clients: Like Client 1 or DECstations running Ultrix 4.2A.
A couple of days ago the /usr/var/spool/mail disappeared on Client 1. The
first symptom was that users started complaining that they had lost their
incoming mails. According to "mount" and "df" the filesystem was not
mounted. Ls gave output like
# ls -l /usr/var/spool/mail
lrwxrwxrwx 1 root system 20 Apr 29 08:34 /usr/var/spool/mail
i.e. the ->/tmp_mnt/... was missing.
Then the root disk(partition) on Client 1 started to fill up (so users
couldn't send mail a.o.). Neither 'find / -xdev -ls' nor 'lsof /' gave me
any clou to what was filling the disk.
As I was getting ready to reboot Client 1, the contents of
/usr/var/spool/mail suddently reappeared and there was again plenty of
space on the root disk.
I found no traces of these problems in the syslog or with uerf.
During all this the other clients functioned normally.
