Re: Serious write-performance problems on RHEL6

Ah derp, my mistake, I apparently didn't scroll down far enough.

Do you know if the slapd procs are sitting in an IO wait state?

When you run a ps -eLf how many slapd threads are there?

I'm going through a migration from Sun One 5.2 to 389ds also. You can setup a 389 DS replica of a Sun One master. It works out pretty well. My plan is to slowly replace our Sun One replicas with 389 DS replicas that are tied to a 389DS hub. Once all the Sun One replicas have been replace, I then promote that 389 DS hub to master and we're done.

Hi, Dustin

Thanks for the rapid response.

I did - sorry for not making that clearer (it was buried in the footer).

I added indexes for the equivalent attributes from our current servers,
and then re-indexed all attributes by unchecking and re-checking
one of the checked boxes for _every_ indexed attribute and clicking "Save".

Since then, I've used the following which I understand re-indexes
every attribute by default (but let me know if I've misunderstood!)

/usr/lib64/dirsrv/slapd-${HOSTNAME%%.*}/db2index.pl \
-D "$ADMIN_USER" -w "$ADMIN_PASSWD" -n userRoot -v

Best wishes,
Steve

When you did your import, did you make sure that your indexes got rebuilt?

The directory contains custom attributes, some of which are CoS,
and many of which have been indexed (AFAIK, all attributes have been re-indexed).
