Hi Kevin,
We have the same thoughts. 2 mongod process working with 2 seperate rugged pc. And 2 rugged pc has own local disc. I suspect discs. Discs, CPU or everything are seperate. The corruption on the 1st server somehow breaks the 2nd server as well.
This is how we are going now.
Corruption happens to often 
I tried --repair option before open a ticket here, but i didn’t found any solution.
Out disc is ext4 and mongodb is strongly recommended to use xfs file system. You think could this be the problem?
I’m working a lot of project with mongo. We are using virtual machine for mongo and the disc coming from storage. I didn’t have any problems with those projects.
Yes agree but what is the problem? I need to find problem. Maybe hardware problem. If I can prove it’s a hardware problem, I can request a hardware replacement.
Do you have any idea ?
Thanks.
