We know that during the ODA patching, a new grid version will be installed. To avoid the /u01 file system to fill up, we need to cleanup the old version. In this blog, I will show you how you can do it and also few changes coming with version 19.29, as you might need a reboot before.
Remember that until 19.28, the patch of the server was done with odacli update-server command, and this will patch the whole server (OS, ILOM, BIOS, …) and the grid in the same step.
Starting 19.29 you will run the server and the grid patching separately. odacli update-servercomponents will patch the server (OS, ILOM, HMP, firmware for local disk and controller, …) and odacli update-gihome will patch and install the new grid version. A reboot of the node will only be performed after the servercomponents update due to the ILOM and BIOS update.
Once the patching process was successfully done, we can cleanup old grid version. In my example, I patched the ODA from version 19.28 to 19.30.
Check usage
First of all we check usage of the grid files. The new grid version is 19.30, so I expect to have file using 19.30 grid.
[root@ODA01 ~]# lsof | grep "/u01/app/19.30.0.0/" | wc -l 29545
Before any cleanup, I need to ensure the old 19.28 grid infrastructure is not used any more.
[root@ODA01 ~]# lsof | grep "/u01/app/19.28.0.0/" | wc -l 3295
Which is definitely note the case.
I check which process are still using old grid infra.

So OAK and TFA are still running on old grid version and using old grid jar library.
This comes from the fact that after the server components patches, the server is rebooted, the oak, tfa and other process will start with the existing grid version, 19.28. The grid patch will not reboot the server and not restart those processes, so they will still run with old grid infra.
This is why before any cleanup and starting 19.29 only, we need to reboot the ODA.
Reboot the DOA:
[root@ODA01 ~]# systemctl reboot [root@ODA01 ~]#
After reboot we can see that only new grid version is used:
[root@ODA01 ~]# uptime 16:16:17 up 3 min, 1 user, load average: 2.06, 1.58, 0.65 [root@ODA01 ~]# lsof | grep "/u01/app/19.28.0.0/" | wc -l 0 [root@ODA01 ~]# lsof | grep "/u01/app/19.30.0.0" | wc -l 45798 [root@ODA01 ~]#
Cleanup old grid
Current space for /u1 is 6.2 GB:
[root@ODA01 ~]# df -h / /opt /u01 Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroupSys-LogVolRoot 30G 5.1G 23G 19% / /dev/mapper/VolGroupSys-LogVolOpt 48G 26G 20G 57% /opt /dev/mapper/VolGroupSys-LogVolU01 49G 41G 6.2G 87% /u01 [root@ODA01 ~]#
Remove old version of grid:
[root@ODA01 ~]# cd /u01/app [root@ODA01 app]# mv 19.28.0.0 BAK_19.28.0.0 [root@ODA01 app]# lsof | grep "/u01/app/19.28.0.0" | wc -l 0 [root@ODA01 app]# lsof | grep "/u01/app/BAK_19.28.0.0" | wc -l 0 [root@ODA01 app]# rm -rf BAK_19.28.0.0 [root@ODA01 app]#
Check current space:
[root@ODA01 app]# df -h / /u01 /opt /boot Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroupSys-LogVolRoot 30G 5.1G 23G 19% / /dev/mapper/VolGroupSys-LogVolU01 49G 27G 20G 58% /u01 /dev/mapper/VolGroupSys-LogVolOpt 48G 26G 20G 57% /opt /dev/md126p2 488M 218M 235M 49% /boot [root@ODA01 app]#
We have taken back about 14 GB.
Check oracle inventory
Checking oracle inventory:
[root@ODA01 app]# cd /u01/app/oraInventory/ContentsXML/ [root@ODA01 ContentsXML]# cat inventory.xml
You will see both grid home:
<HOME NAME="OraGrid192800" LOC="/u01/app/19.28.0.0/grid" TYPE="O" IDX="13"/>
<HOME NAME="OraGrid193000" LOC="/u01/app/19.30.0.0/grid" TYPE="O" IDX="15" CRS="true"/>The current running one is the one having CRS option to true.

Check inventory
Checking the inventory again:
[grid@ODA01 bin]$ cd /u01/app/oraInventory/ContentsXML/ [grid@ODA01 ContentsXML]$ cat inventory.xml
We will see old grid with option REMOVE=”T”
