The load starts out at a rate of about 2 M/s. In the past I remember that dropping to something like 900 k/s and staying there. Now the load starts in the same place, but after 30 seconds it alternates between stalling out right, and a rate under 100 k/s. Dips as low as under 10 k/s and sometimes as high at 700 k/s. (My undergraduate degree was in watching water boil.)
What is the partition type? ext4?
What options are set for the partition in fstab?
This is what I am currently using. The UUID are obviously shortened for readability.
UUID=blah1 / ext4 defaults,acl,noatime,errors=remount-ro 0 1 UUID=blah2 /var/cache/openafs ext4 defaults,noatime 0 2 UUID=blah3 /var/lib/ldap ext4 defaults,noatime 0 2 UUID=blah4 none swap sw 0 0
I also tried ext3 with the same results. This is on a raid-1. I have also tried splitting the two disks and putting the OS on one and the LDAP database on the other. None of this moved the problem.
It really has the feel of a resource exhaustion. The load is now stalled in that the progress display is not updating. top does not show slapd as doing anything.
