Archivos borrados no liberados ( lsof | grep deleted)

 

No liberaba espacio en el /home y el du -sh /home me mostraba que habia solo 1.8gb ocupado.

[root@p home]# df -h .

Una busqueda mas fina , directamente sobre el fs /home

[root@ home]# /usr/sbin/lsof | grep deleted |grep home

Si quiero saber el tamaño total en Bloques, de los archivos borrados en el filesystem /home

[root@ home]# lsof -Fn -Fs |grep -B1 -i deleted | grep ^s  | cut -c 2- | awk '{s+=$1} END {print s}'
5494756694
[root@ home]# 

Ya identificamos el proceso que quedo estaba ejecutandose y cuanto ocupaba, ahora vamos a liberar ese espacio.

[root@home]# /usr/sbin/lsof | grep deleted |grep /home
