Hi,
Normally for a Domino server, I would partition about 5G for the OS (Drive c:). Now, we are moving to AIX 5.1, and already configured the server.
Is it necessary to configure the partition to 5G as per what I have done in Windows? I have /home, /opt, /var, / all for 65Mb, /tmp for 256Mb. So, does it mean that I need to change root (/) from 65Mb to 5Gb?
thanks
Subject: normally you have no Domino data in the root filesystem - create different volume groups and filesystems
it makes sense to have at least separate filesystems for
notesdata
transaction log
view rebuild
we normally have structure like
/local/servername/notesdata
/local/servername/translog
/local/servername/view_rebuild
for each server and mount the filesystems accordingly.
It is recommended that you have different volume groups for the different filesystems to spread the load to different physical volumes. Normally you put translog and view_rebuild on RAID1 and can choose RAID5 for data. This kind of configuration does even make sense for SAN.
Domino on UNIX gives you much more flexibility and with the LVM (logical volume manager) you can increase the size of a filesystem very easy and can even add new disks to existing volume groups/filesystems …

You cannot even think of AIX disk space allocation like a Windows box.
In AIX, a pool of one or more hard drives belongs to a “volume group” you then make “filesystems” within that volume group.
The operating system (and all its filesystems such as /, /usr, /var, /opt, /tmp, /home and so forth) belongs within the “rootvg” volume group. You really do not ever want to “pollute” the operating system’s filesystems with applications such as Domino, sql database engines, whatever. A “properly” set up AIX server will have some other hard drives allocated to a different volume group. On my servers, I typically have a “rootvg” and a “datavg” or “appsvg”, and nothing other than the operating system itself, and maybe some tools like C compiler, GNU utilities, etc, ever get placed into filesystems within the rootvg. I deliberately keep the rootvg’s filesystems allocated as small as possible.
Since my Domino server machine has a pair of individual hard drives as the rootvg (software mirrored for fault tolerance) and one big raid array as the “datavg”, I simply put my Domino installation into a “/notes” filesystem that resides within my “datavg” volume group. It’s presently about 20GB and growing daily. I didn’t bother with making separate filesystems for domino executables, notesdata, transaction logging, etc, as some folks like to do since all this i/o is going to a single raid array anyway, so there’s no real benefit to me in separating it up into a more complex model.
I leave the AIX operating system’s filesystems at their original small sizes and only grow them as necessary, since I do not know what the future will unfold and I prefer to keep all that free unallocated space on the hard drives in the rootvg available for a rainy day in case I need a big chunk of diskspace to allocate for unforseen emergencies.

My root file system is growning and I no see how, I have domino 6.5.1, I recently put a crontab task to backup some nsf. errpt reported me “UNABLE TO ALLOCATE SPACE IN FILE SYSTEM” it was 131072 I expand the file system to 262144, but again it 98% full, what can be the problem,
thanks for your help.
