vxfs/jfs: bavail vs. bfree

[Paul Tibbitts]

Mostly, these values (from fstyp -v) seem fairly close on our jfs/vxfs filesystems, like this:

f_bfree: 171000
f_bavail: 158784

Except for one filesystem (/var), similar sized to the above:

f_bfree: 82895
f_bavail: 0

Using bdf (or df) on /var shows 90% used, but some programs fail (vi won't create temporary files in /var/tmp.) However, at the same time, users (not just root) can copy files to /var without errors.

Thanks for any suggestions.

bavail normally means blocks available to a non-superuser but that should only apply to hfs filesystems. It would help if you displayed the entire fstyp -v output, the df -t output, the output of mkfs -F vxfs -m /dev/vg00/lvol8 (or whatever the device node for /var is) would also be helpful. Note that the -m version of mkfs does not create a filesystem but displays the options used to build the filesystem.
