Hi guys I promise this is the last question I ask of nominatim!! I have a new machine with 500 gb HD and 16 gb RAM. I will install centOS 6.6 on this and I would like to know how to partition the drive. Because if I do the normal configuration as follow: And I will install postgresql by yum, I will need to create a cluster for postgres because, with yum, the data folder will be placed under Than is madness to create a system as follows: ?? What would be the optimum configuration knowing that I have to install postgres with yum?? Thanks a lot |

From memory Redhat and derivatives have always had that "odd" approach to partitioning. Given that you won't have huge /home directories, I'd explicity remove those and allocate "the rest of the disk" to /, since you don't want to create an artifical point of failure where a partition is full. How hard the installation process will make this task for you I don't know, because I haven't installed a vanilla Redhat system for a while. One other thing to watch for - check the version of any frequently-updated package (such as Postgres) that yum offers against the latest source version to make sure you aren't installing a very out-of-date version. I don't know that it'll be a problem, but it's something to check. You've probably already seen the page in the wiki; if not: http://wiki.openstreetmap.org/w/index.php?title=Nominatim/Installation_on_CentOS&oldid=1180464 |
How can
/var/lib/pgsql/9.4/databe located under/root? These are completely different paths. Usually/rootwill never ever contain any large data, just a few tiny config files. I think misread root to be/rootalthough it was meant to refer to '/' which is also called the root directory.Yes Scai you're right. I mean "/" partition. The problem is that if I create a default centOS machine the system will configurate as follow (for example on a 500gb disk):
Then when I go to install postgresql by yum, it put the
datafolder under/var/lib/pgsql/9.4/and it is surely under "/" because it has 50gb free space.Now I can't install postgresql manually and I need more space for the data folder, then I create a postgres cluster but I prefer don't do it again...
For these reasons I asked if there is an optimal configuration for this job (nominatim). The machine is been created just for this. Is a server in wich I will install just nominatim and graphhopper.. stop.
Thanks.
Then assign more space for "/" during installation and less to /home which you won't really need. There is no "optimal" configuration, just make sure you have enough disk space for your database. It won't run faster or slower if you assign more or less space to /boot or /swap.
