Nodediag provides an extensible TAP framework for executing node diagnostic checks at system startup.
Tests installed in /etc/nodediag.d/ are run in parallel by the nodediag
command:
Checking cpucount: [ OK ]
Checking ecc: [ OK ]
Checking infiniband: [NOTRUN]
Checking ethernet: [ OK ]
Checking mpt2sas: [ OK ]
Checking mptsas: [ OK ]
Checking network: [ OK ]
Checking sbe: [ OK ]
Checking swap: [ OK ]
Checking dmi: [ OK ]
Checking tw: [NOTRUN]
Checking tapwrap: [ FAIL ]
Checking hdparm: [ OK ]
Expected results are configured in /etc/sysconfig/nodediag
or /etc/sysconfig/nodediag.d/testname.
Tests can be listed with nodediag -l:
cpucount: Check number of CPU cores
dmi: Check dmi table values
ecc: Check EDAC ECC type
ethernet: Check ethernet config
hdparm: Check hard drive read performance
infiniband: Check infiniband config
mpt2sas: Check mpt2sas cards
mptsas: Check mptsas cards
network: Check network config
sbe: Check Single Bit Memory Error Count
swap: Check for expected amount of swap
tapwrap: Run non-TAP tests: nvidia
tw: Check 3ware cards
An init script is provided so diagnostics can be run at startup, with
the (verbose) results redirected to /var/log/nodediag.
Alternatively nodediag can be run as part of a cluster bringup
procedure, determining whether a node is fit to start cluster services;
or as part of a resource manager epilog between batch jobs to detect
emerging problems.
