Introduction
On Mammoth upgrades from a release prior to BDA V4.7 to a release BDA V4.7 or higher disk partition warnings can be raised. The reasons for this are that the Mammoth upgrade is not handling all possible existing disk partition configuration layouts correctly or the Mammoth upgrade is not succeeding to upgrade the disk partition configuration. Note that any combination of partitions could be incorrectly labeled.
This can happen on Mammoth OL5 or OL6 upgrades. The only differences between OL5 and OL6 upgrades is: 1) the way the symptoms appear and 2) the specific steps to resolve. In OL5 Mammoth upgrade will not normally do a reboot, so the issue appears at the end of the upgrade. On OL6, Mammoth upgrade normally does a reboot at the end of Step 2 so the issue appears after the reboot. This will happen at the end of Step 2 on OL5 if a reboot is necessary.
To resolve on on OL5 follow the steps in this note. To resolve on OL6 follow the steps in After Mammoth OL6 Upgrade Step 2 Reboot /root/BDA_REBOOT_WARNINGS reports "WARNING: Wrong OS disk s1 partition info" (Doc ID 2303031.1).
Note: The issue raised in: "WARNING: Wrong OS disk s0 partition info" On BDA V4.5/BDAV4.5 OL6 with bda rpm 4.5.0-6 and correct partition state. (Doc ID 2309143.1), looks similar but is different. This occurs when BDA Mammoth v4.5.0 or BDA Mammoth v4.6.0 is being deployed on the v4.5.0-6 base image. This issue occurs because the BDA v4.5.0-6 base image uses the new partition labeling scheme. See the referenced note in this case and do not follow the steps here.
Symptoms
The symptoms on OL5 during the cluster verification checks, Step 8, raise a warning like: "Wrong OS disk s0 partition info : 1 ext3 raid 2 ext3 raid 3 linux-swap 4 ext3 ext3". The same is raised by bdacheckcluster/bdachecksw. The same warning is also raised in /root/BDA_REBOOT_WARNINGS if there was a reboot during the upgrade Step 2.
Messaging looks like:
bdanode0x: WARNING: Wrong OS disk s0 partition info : 1 ext3 raid 2 ext3 raid 3 linux-swap 4 ext3 ext3
bdanode0x: INFO: Expected OS disk s0 partition info : 1 ext3 raid 2 ext3 raid 3 linux-swap 4 ext3 primary or 1 ext3 primary raid 2 ext3 primary raid 3 linux-swap primary 4 ext3 primary or 1 ext4 primary
