I was about to ask a question at ServerFault, but I doubt it could be closed as off-topic, thus it would be better to ask here first.
In a brief my question would be asking for an advice on what could go wrong with ext4 filesystem on LVM on hardware RAID6 as I thought this particular setup was very robust and proved itself to be so for more than 7 years of replacing failed drives and all was fine. Recently however this system experienced a disastrous failure.
I analysed all the information I could gather (logs, course of events from memory, filesystem failure mode etc), but ultimately was unable to conclude, what exactly failed and most importantly why. I hope that given all this information in question body someone experienced could suggest a failure and the cause of this.
My concern is that on the one hand this particular question and answers might be relevant and useful, but on the other hand it is rather specific... kinda...
So the questions are:
- Is this kind of questions on-topic for StackExchange?
- If not - are there any ways to make this question on topic. Reword it or something?
- Is ServerFault the best site to ask it?
- If not - which is?
