Os servidores do meu trabalho possuem um script feito por mim que toda meia noite copia os arquivos de log para uma pasta, copia essa pasta para o Amazon S3 e zera os arquivos originais.
Porém, vi que os arquivos originais não foram zerados e isso está afetando o espaço em disco.
O comando que uso é o seguinte:
cat /dev/null | tee /etc/vinter/logs/*
Hoje tentei usar esse comando separadamente e não funcionou. Depois disso, tentei outros dois e nenhum funcionou.
[root@APPSERVER11-S1 ~]# cat /dev/null | tee /etc/vinter/logs/*
[root@APPSERVER11-S1 ~]# ls -l /etc/vinter/logs/*
-rw-r--r-- 1 root root 9223905280 Sep 11 12:47 /etc/vinter/logs/rsp.appserver11-s1.apigoldnode-1.rsp.log
-rw-r--r-- 1 root root 9468202 Sep 11 12:47 /etc/vinter/logs/Services-APIGOLDNODE-1.log
-rw-r--r-- 1 root root 0 Sep 11 12:47 /etc/vinter/logs/Services-APIGOLDNODE-1.log.1
[root@APPSERVER11-S1 ~]#
[root@APPSERVER11-S1 ~]#
[root@APPSERVER11-S1 ~]# echo -n | tee /etc/vinter/logs/*
[root@APPSERVER11-S1 ~]# ls -l /etc/vinter/logs/*
-rw-r--r-- 1 root root 9224224768 Sep 11 12:48 /etc/vinter/logs/rsp.appserver11-s1.apigoldnode-1.rsp.log

-rw-r--r-- 1 root root 0 Sep 11 12:47 /etc/vinter/logs/Services-APIGOLDNODE-1.log.1
[root@APPSERVER11-S1 ~]#
[root@APPSERVER11-S1 ~]#
[root@APPSERVER11-S1 ~]# printf '' | tee /etc/vinter/logs/*
[root@APPSERVER11-S1 ~]# ls -l /etc/vinter/logs/*
-rw-r--r-- 1 root root 9224380416 Sep 11 12:48 /etc/vinter/logs/rsp.appserver11-s1.apigoldnode-1.rsp.log

-rw-r--r-- 1 root root 0 Sep 11 12:48 /etc/vinter/logs/Services-APIGOLDNODE-1.log.1
Também não está funcionando individualmente:
[root@APPSERVER11-S1 ~]# echo > /etc/vinter/logs/rsp.appserver11-s1.apigoldnode-1.rsp.log
[root@APPSERVER11-S1 ~]# ls -l /etc/vinter/logs/*
-rw-r--r-- 1 root root 9236357120 Sep 11 12:58 /etc/vinter/logs/rsp.appserver11-s1.apigoldnode-1.rsp.log
-rw-r--r-- 1 root root 520807 Sep 11 12:58 /etc/vinter/logs/Services-APIGOLDNODE-1.log
-rw-r--r-- 1 root root 10264642 Sep 11 12:54 /etc/vinter/logs/Services-APIGOLDNODE-1.log.1
O truncatecomando, conforme instruído nos comentários, não funcionou tão bem:
[root@APPSERVER11-S1 ~]# truncate -s 0 /etc/vinter/logs/rsp.appserver11-s1.apigoldnode-1.rsp.log
[root@APPSERVER11-S1 ~]# ls -l /etc/vinter/logs/

-rw-r--r-- 1 root root 0 Sep 11 13:06 Services-APIGOLDNODE-1.log.1

Tentei em outro servidor e apenas o arquivo atualizado mais constantemente (muitas linhas por segundo) não foi zerado. Será que o arquivo é atualizado tão constantemente que nem consegue ser zerado?

O sistema de arquivos de partição deste segundo servidor /é xfs, como o primeiro.

Às vezes, alguns dos arquivos de log são zerados, mas retornam ao tamanho original alguns segundos depois.

O que pode estar errado?

Você tentou excluir o arquivo inteiro à força executando?
# rm /var/log/logfile -f
