Re: Out of space

Tom,

Here's the situation:
[root(at)linux04 init.d]# cd /var/lib/pgsql/data/
[root(at)linux04 data]# ls -l
total 1494316
-rw------- 1 postgres postgres 4 Jun 21 2001 PG_VERSION

-rw------- 1 postgres postgres 16777216 Apr 7 12:14 000000010000001E

I do have a limited amount of space in the partition but I'd like to get rid
of more. Just not sure what to delete if anything.

This is just trying to make a new, empty xlog file. I don't quite
understand why the errno is "No such file or directory" --- you wouldn't
think that write() could return that errno. But the most likely bet is
that you don't yet have enough free space on the disk. These files are
16MB each, and it could be that more than one needs to be made.

How much stuff is there in /var/lib/pgsql/data/pg_xlog anyway? I think
that 7.1.2 predates some changes we made to keep down the number of xlog
files that would be kept around.
