Unable to run lvreduce command due to missing program 'blockdev'. (The missing program 'blockdev' is part of the util-linux-extras package.)


Cannot reallocate the vmdisks app volume.


Attempting to reallocate disk resources when upgrading a vCMP system.


Acquire the /sbin/blockdev executable from a different BIG-IP device running version 11.6.0-HF6 or 12.x, and install it on the BIG-IP device affected by this issue. Note: If the receiving system is a multi-blade VIPRION, you must install the file on each blade. If you do not have a suitable donor device available, you can contact F5 Support, who will be able to supply the executable to you. Note: Using a blockdev executable from another source is not recommended.

Fix Information

The blockdev utility is now present, so you can run the lvreduce command to reallocate the vmdisks app volume.
