Hi, I run out of disk space on the box and had to delete some files and restart postgres. Ever since I have been getting the above message. PS shows this process: 9351 ? D 0:04 postgres: startup process Running an strace on this process shows that it is trying to write 8K of zeros to a file called 023D in pg_clog but fails at 224K and it just keeps trying forever. I tried replacing the file with one I created - 256K as the other files in the pg_clog and filled with zeros. But it keeps doing the same thing : open("pg_clog/023D", O_RDWR|O_CREAT|O_LARGEFILE, 0600) = 10 _llseek(10, 221184, [221184], SEEK_SET) = 0 write(10, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 8192) = 8192 fsync(10) = 0 close(10) Any ideas on what might be causing this and what I can do to fix it will be greatly appreciated. Need to get it fixed fast. Many Thanks valiouk __________________________________________________________ Not happy with your email address?.
