Isilon, Isilon, how do you work… no one really knows. However here are a few useful, seemly undocumented commands you can run when ssh’d into a node:
Finding large files
fstat is a bit like lsof in the Linux world, but exists on FreeBSD:
fstat | sort -k 8 -n -r | more
Finding serial number
isi config
quit
gathering and uploading info, usually required for a support call
isi_info_gather
Show status/alert info
isi status
isi alerts
Do something on all cluster nodes
isi_for_array 'df -h'

A couple of ways for write multiply, without using multiply…
int multiply(int value,int mul) {
int ret=0;
int mulabs = mul;
if(mulabs < 0) mulabs = 0 – mulabs;
for(int n=0;n<mulabs;n++) {
ret += value;
}
if(mul < 0) ret = 0-ret;
return ret;
}
int multiply2(int value,int mul) {
int total=0;
for(int n=30;n>=0;n–) {
if((mul & (1 << n)) > 0) {
total += value << n;
}
}
return total;
}
