Delete syslog but size disk can't increase

Hi Experts,

I have a problem wih /var. Disk /var is full. After i investigate, i found file /var/log/syslog.0 is growing rapidly. The size is 4.3G. I tried to move syslog.0 to another disk and file was moved successfully.

My question is why size /var can't increase? used space still 100%.

When i check the size of syslog.0 in place that i moved, the size is 4.3G. But free space of /var still 0%

I'm using Solaris 10.

Please share your thought/experience.


Thanks
Edy
