Exadata Compute node patching prechecks:
Below commands will be used for Exadata compute node/DB node patching prechecks:
Note : Here we are applying QFSDP patch which is released on Jan2022
#cd /QFSDP/Jan_2022/33567288/Infrastructure/SoftwareMaintenanceTools/DBNodeUpdate/21.211221
#./dbnodeupdate.sh -u -l /QFSDP/Jan_2022/33567288/Infrastructure/21.2.8.0.0/ExadataDatabaseServer_OL7/p33665705_212000_Linux-x86-64.zip -v
While doing patching prechecks on compute node if you get below error then
Error :
ERROR: Inactive lvm (/dev/mapper/VGExaDb-LVDbSys2) (15G) not equal to active lvm /dev/mapper/VGExaDb-LVDbSys1 (30G). Backups will fail. Re-create it with proper size
Ans:
1. The error clearly shows that there is size mismatch between LV /dev/mapper/VGExaDb-LVDbSys2 and /dev/mapper/VGExaDb-LVDbSys1
2. The inactive root LV is having 15GB size and the active root LV is having 30GB size.
we can check it by using command
#lvs
3. Make the inactive root LV same as size of active root LV
4. Command:
#lvextend -L +15G /dev/mapper/VGExaDb-LVDbSys2
5. Verify using command:
#lvs
