All you have to do to restore your database is run restorexCATdb -p <path
to you backup directory>. It will replace all the tables. You should
never remove any of the files manually and you do not have to stop
xcatdb. But since it looks like you already have removed files, do
the restore in bypass mode.
service xcatd stop. ps -ef | grep xcatd and make sure all processes are
gone.
export XCATBYPASS=y
restorexCATdb -p <path to you backup>
unset XCATBYPASS
service xcatd start

Jarrod,
%bphash isn't coming into xnba.pm::setstate as expected. Data::Dumper
shows:
BPHash: $VAR1 = 'c4u34';
$VAR2 = [
undef
];
Compared to my working 2.8.4 cluster:
BPHash: $VAR1 = 'c0u13';
$VAR2 = [
{
'kcmdline' =>
'imgurl=http://172.20.0.1:80//install/netboot/rhel6_c/x86_64/compute/rootimg.gz
XCAT=!myipfn!:3001 NODE=c0u13 FC=0 console=tty0 console=ttyS0,115200',
'kernel' =>
'xcat/osimage/rhel6_c-x86_64-netboot-compute/kernel',
'initrd' =>
'xcat/osimage/rhel6_c-x86_64-netboot-compute/initrd-stateless.gz'
}
];
So, it feels like I have a corruption in the database, maybe a hash or key
is screwed up causing the hang and problems. I have a backup of the
database files from dumpxCATdb. What's the best way to clear out and
restore the database files from the backup.
I tried to stop xcatd, remove all the /etc/xcat/*.sqlite files and
restart xcatd, but it complains. What is the approved procedure to restore
sqlite files from backup?

The times are right on. I am looking through the xnba.pm module now. The
value that is getting set:
# cat /tftpboot/xcat/xnba/nodes/c4u34
#!gpxe
#netboot rhel6_c-x86_64-compute
LOCALBOOT 0
is the DEFAULT case in the IF statement. I am going to start putting in
some comment lines to see where it's hanging in the code. Maybe there is
something wrong with xcatd and the sqlite database files that's causing
things to hang or return incorrect data.
Any suggestions on what I should be looking for would be helpful.

Jarrod,
Sorry. The rsetboot isn't taking a long time. It's just nodeset that
is. I cut/pasted a group of commands into the terminal for the system I was
working on (nodeset, rsetboot, rpower) and it hung on nodeset. So, there is
something going wrong with nodeset. I have another xCAT iDataplex cluster
(my testing cluster) which I upgraded to 2.8.4 and it isn't having a
problem:

Granted my test cluster is only a few nodes. But still, it's updating
everything correctly. I also noticed that the node I put through discovery
on 2.8.4 showed discovery method as "UNDEF" according to nodediscoverls:
# nodediscoverls | grep c4u34
18F64EE1-3CC1-DF11-B526-E41F134D13C2 c4u34 undef
7323AC1 23DF198
Where are my other nodes show it as "switch":
# nodediscoverls | grep c4u33
0ED7839B-3FC1-DF11-B752-E41F134D42D8 c4u33 switch

Odd that rsetboot should take a long time. I assume something like rpower

Subject: [xcat-user] Upgraded to xCAT 2.8.4, nodeset not working as
expected.
Good morning,
I upgraded xCAT via yum last week from 2.8.3 to to 2.8.4. Since then, if
I put a node (in this case a dx360M3) through discovery, discovery
completes, but if I then try and use nodeset to use toolscenter or set this
diskless image on the node (nodeset XXX osimage=), it isn't working.
I'm noticing that the nodeset and rsetboot commands are taking > 30
seconds to complete and when I reboot the node, it just tries to boot from
disk. A little digging and it appears that nodeset isn't updating the
underlying files on /tftpboot/xcat/xnba/nodes/* like expected:
# /usr/bin/time -p nodeset c4u34 netboot=toolscenter-x86_64-bomc
c4u34: netboot toolscenter-x86_64-bomc
real 31.20
user 0.11
sys 0.03
# cat /tftpboot/xcat/xnba/nodes/c4u34
#!gpxe
#netboot toolscenter-x86_64-bomc
LOCALBOOT 0
# /usr/bin/time -p nodeset c4u34 osimage=rhel6_c-x86_64-netboot-compute
c4u34: netboot rhel6_c-x86_64-compute
real 49.85
user 0.12
sys 0.01
# cat /tftpboot/xcat/xnba/nodes/c4u34
#!gpxe
#netboot rhel6_c-x86_64-compute
LOCALBOOT 0
The long time makes me think it's hitting a timeout value and aborting.
Did I miss something with the upgrade to 2.8.4? I have no problems with
2.8.3 and discovery is working on 2.8.4.
Thanks,
