t3fs05 emergency OS reinstallation (Solaris 10 u8)
In this emergency downtime, the main effort had to be spent at a complete reinstallation of t3fs05.
A detailed report on the fileserver problem leading to this can be found in
IssueDcachePoolHangs.
The detailed setting up of the new system is documented in
SolarisOsReinstall.
OS upgrade on all nodes
On the UI, one needs to make sure that at this stage no grid software is updated.
yum update --disablerepo=glite-UI --disablerepo=dag
On all other nodes, a simple
yum update
was enough.
Take a look at the
/boot/grub/menu.lst
file and make sure that the kernel boot parameters include the console redirection options
console=ttyS0,9600
!!!
Reboot of all machines
t3se01:
Needed to adapt jdk home directory in /opt/d-cache//etc/srm_setup.env (JAVA_HOME=/usr/java/jdk1.6.0_17)
MW upgrade on the UI
Update the rest of the package, now with the enabled MW repositories
yum update
Test the new YAIM version against the existing node config:
