Fazendo a compressão dos logs

[root@spdc00 log]# cd /var/log
[root@spdc00 log]# gzip srm-spdc00Domain.log
[root@spdc00 log]# mv srm-spdc00Domain.log.gz srm-spdc00Domain.log.gz.3

Agora vamos ligar novamente os serviços. Primeiro o Phedex

[root@spdc00 root]# su - phedex
[phedex@spdc00 phedex]$  Master -config ~/SITECONF/local/PhEDEx/Config.Prod start

como root

voltando à SPRaid

[root@spraid root]#  /opt/d-cache/bin/dcache-core start
Starting dcache services:
Starting gridftp-spraidDomain  6 5 4 3 2 1 0 Done (pid=12023)

[root@spraid root]#  /opt/d-cache/bin/dcache-pool start

Starting dcache pool: Starting spraidDomain  6 5 4 3 2 1 0 Done (pid=12290)

Vamos verificar o espaço:

[root@spdc00 log]# df -h
/dev/sda5             2.0G  1.8G   72M  97% /var

Piorou! Melhor mover os logs comprimidos para outro lugar:

[root@spdc00 log]# mv /var/log/srm-spdc00Domain.log.gz.* /home/mdias/.
[root@spdc00 log]# df -h
/dev/sda5             2.0G  1.6G  276M  86% /var

ainda é muito. entretanto

[root@spdc00 log]# lsof /dev/sda5
COMMAND   PID   USER   FD   TYPE DEVICE       SIZE   NODE NAME
tail     1635  mdias    3r   REG    8,5 1278886709 131165 /var/log/srm-spdc00Domain.log (deleted)
[root@spdc00 log]# kill -9 1635
[root@spdc00 log]# df -h
/dev/sda5             2.0G  417M  1.5G  22% /var
[root@spdc00 log]# mv /home/mdias/srm-spdc00Domain.log.gz.* /var/log/.
[root@spdc00 log]# df -h
[root@spdc00 log]# mv /home/mdias/srm-spdc00Domain.log.gz.* /var/log/.
[root@spdc00 log]# df -h

Sorry! deveria ter fechado o tail de monitoramento antes. Burrice!

No monitoramento do phedex estamos UP em tudo na instância production. No dCache OK tanto em Cell service quanto Pooll usage
