Affected Product(s):
BIG-IQ Device
Known Affected Versions:
5.3.0
Opened: Mar 28, 2018 Severity: 3-Major
The framework upgrade fails at the end when attempting to remount the /usr partition as RO. The DB monitors on BIG-IP had a java process open which prevented remounting RO. The framework upgrade actually succeeds but because the remount fails it appears to fail. If you delete and re-add the device everything appears ok, however the /usr partition is still in RW which is not recommended.
Framework upgrade appears to fail and the /usr partition is in read-write mode.
- BIG-IQ updates the framework (per-11.6 devices). - BIG-IP has active DB monitors.
On BIG-IP. 1. Find the PID of the process holding the open files that prevent remounting /usr using 'lsof -n'. Look for files with the DEL attribute. It should be a java process. 2. Kill that process. NOTE: DB monitors mail show failures at this point. The monitors will come backup again and return to normal. 3. Remount the /usr partition. 'mount -o remount,ro /usr'
