Greetings,
We have two systems (E4000 and E4500) each attached to an A5000 FC array.
The machines are running Solaris 8 2/02 with the latest rec. patches and
firmware, and the arrays have the latest firmware. Alternate pathing is
enabled. These machines are used as mail servers, and half of the drives
in each A5000 are mirrored with SDS. This space is mounted as /var/mail,
and UFS logging is enabled.
The /var/mail filesystems hold between 2000-13000 user mail files of varying
sizes. When the filesystem was created, the directory file was only a few
hundred K bytes each. After about a week, the directory file is now over
100M and still growing.
drwxrwxr-x 3 root mail 165218816 Jul 25 07:53 /var/mail
We expect it to be large, but not this large. We have been unable to find
an explanation for this exponential increase on sunsolve or google/usenet. To
my knowledge, the overhead of UFS logging (a max of 64M according to the
mount_ufs man page) would not be represented here, as that is stored in
the free space of the filesystem.
Does anyone have ideas or suggestions on why this is happening?
Thanks.
