Hi Gurus
We are facing a peculiar issue with respect to pg 12 and pg14 on RHEL8u10,post os patch objects are getting corrupted. The details are unknown until we access the object's.
System Stack:
Db: pg12.22,pg14.19
Os : Rhel 8u10
THALES CTM FOR encryption solution
Stirage : Pure storage and VSAN DISK
We are not seeing any errors reported with respect to the corruption,unless until we select The problematic object that to the problematic block only
Below corruption scenarios we observed
1) if the corruption happen on standby node no impact to the production
2) if corruption happen on production we could see same object we are unable to select from standby node,means corruption is transfer to standby node
3) if the corruption happen on block 0 it is not allowing to perform any DML activity,if it is on other blocks it is allowing to insert/update/delete in other good blocks,if system touches the problematic block only it is failing
Need your guide lines how to identify what is going wrong,and where is going wrong?
Is there any known bugs in these version with the given stack pg12/14 with RHEL8u10
Is there any way we can stop not to replicate the problematic block to standby node?
What will be the best practice to identify the problematic objects or blocks
We tried amcheck on pg14 it is not giving any results
Your expertise advise will be help us on coming out of the critical issue
