Обсуждение: Add a new disk to data directory

Hi all,


I need to add a new disk to the data directory of postrgreSql ( the
one i ve got is running out of space), how can i do that?, i have
postgreSql 8.0.3 on a Mandrake Linux 10.1 machine (hp proliant ml350
g3)

Do I have to use LVM (Logical Volume Manager)?
Is there any workaround in postgreSQL?

I will apreciate any help you people could give me.

All yours
Ing.Jose A Fuenmayor Nava.

I think, using LVM on a database is very risky.

I have changed the whole disk to a 3Ware Raid-5 SATA with
4 and/or 8 Harddisks.  This will save your nerves.

Please note, that if you stop the pgsql and flush the
diskcache you can copy the pgsql-data-dir to the new location.
