If I had to choose between a filesystem with silent and/or visible data corruption up to pretty much eating itself and having to restore an entire server, versus a filesystem for which you can trust but could have a kernel deadlock/panic..I would choose the latter, and in-fact did.
I have seen a few servers with ext4/mdraid over the last five years have serious corruption but have had to reset a ZoL server maybe twice.
- ianhowson 10y agoStory time. I transitioned an md RAID1 from spinning disks to SSDs last week. After I removed the last spinning disk, one of the SSDs started returning garbage. 1/3 reads are returning garbage and ext4 freaks out, of course. It's too late and the array is shot. I restore from backup. This would have been a non-event with ZFS. I've got a few production ZoL arrays running and the only problems I've had have been around memory consumption and responsiveness under load. Data integrity has been perfect.
