Обсуждение: [ADMIN] PostgreSQL 9.3 ERROR

Running on Linux...has anyone else encountered this?

Receiving the following error in the pg_log file:

"could not extend the "pg_tblspc/23917/PG_9.3_201306121/16385/55041.5": wrote only 4096 of 8192 bytes at block 722183"

I was under the impression that PostgreSQL allocates 1G per tablespace file.

Thank you in advance.

That error indicates that the filesystem ran out of disk space.

That is incorrect.  In PostgreSQL, a "tablespace" is a directory.  Every
table in PostgreSQL consists of a set of files.  None of the individual
files for a PostgreSQL table will be larger than 1G, but PostgreSQL will
use multiple files when it reaches 1G in size.

In the above case, the table/index with relfilenode 55041 in the
database with oid 16385 has grown to be over 5G in size.  The files:

55041
55041.1
55041.2
55041.3
55041.4
55041.5

are all associated with that table/index.

Thanks!
