Commands Oliver wants to keep track of, at a minimum.
Case: What is the quota allocation assigned to users within a cluster?
show who has logged in (also shows who is currently logged in)
- last
Shows who is logged in
- w
show quota netid
- where netid is accountID
showall repquota -a
edit edquota netid
- file (read in vi)
- in kilobytes
Case: Turning off compute nodes
ssh to the compute node, then:
- halt -p now
Note: Check jobs aren't running on a compute node by first going to the head node:
- q or pestat (see below)
iptables
Resource John (Brightworks) recommends:
Basic Linux commands
- exit (exit session)
- top (activity, live)
- q, or qq (list nodes and their status; reverset)
- pestat (node listing of every node with lots of info)
- psbnodes -ln (list of down nodes)
- qstatus -f (status of nodes, with details. Just nodes with queued jobs?)
- ifconfig (show network info)
Version info
- cat /etc/issue
- cat /proc/version
