Here are some some useful Isilon commands to assist you in troubleshooting Isilon storage array issues.
Grep the log for stalled drives on the isilon cluster
cat /var/log/messages |grep -o 'stalled: [0-9,*:]*'|sort |uniq -c
(Stalled drives are bad, and can cause cluster problems. you could also run this command on the individual nodes /var/log/restripe.log )
Grep the log for stalled drives on the isilon cluster for month of Sept
grep 'Nov ' /var/log/messages |grep -o 'stalled: [0-9,*:]*'|sort |uniq -cUse this on the restripe.log
grep 'Nov ' /var/log/restripe.log |grep -o 'Stalled drives are \[[0-9,*:]*\]'|sort |uniq -c
When reviewing the results of the stalled drives it is important to note that the drive numbers listed is the logical drive number and not the bay number. You need to run the command “isi devices” on the node with the suspect drive to determine what bay the drive is actually in.

isi_for_array wbinfo -t
To find an open file on Isilon Windows share
isi_for_array -q -s smbstatus | grep
isi_for_array -q -s smbstatus -u| grep to get the user
Note: The isi_for_array command runs the command on all of the nodes. This command will ask for the user’s password so that it can login to the other nodes and complete the command. When passing the results of a “isi_for_array” command to another command such as grep (like the example above) will require the user password so that it can be passed to the other nodes. There is no prompt for the password so you must enter it on the next line and press enter to get the results of the command.
