@quixoticgeek Good luck!
Is now a bad time to tell you about our lord and savior ZFS?
@pooserville ZFS is even worse.
@quixoticgeek That has not been my experience across a few hundred terabytes of data, on Linux/OpenSolaris/macOS. What problems have you run into?
@pooserville When zfs fails. it's incredibly hard to recover any data. When a linux software raid1 fails, you can just ignore the raid, mount the filesystem as is, and recover all your data. It fails open.
@quixoticgeek ZFS mirrors fail open the same way as any RAID 1. (I used to make three-disk mirrors, then just yoink one disk for offsite storage when a remote online backup wasn’t an option. Read fine.) ZFS RAIDZ fails the same way as the equivalent RAID5/6 fails, but with a lot more flexibility in resilvering assuming the number of failed disks is less than the number of redundant disks (spares can be different sizes etc.)
@pooserville still a lot of extra complexity over simple mdadm. Also isn't zfs having all sorts of total data loss bugs of late? mdadm is mature...

@pooserville I've been using mdadm for two decades. Hundreds of not thousands of arrays. All sorts of sizes. And in some cases, nested arrays. I know it's quirks more than is perhaps sane.
@quixoticgeek Fair enough. Best of luck with your current issue!
