Exadata Compute node patching prechecks error_Inactive lvm

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
