I quite like XFS + LVM. LVM now has a high level wrapper for kernel raid and md-integrity.

for previous data I can't bear to go less than raid 6 (equiv). And require ECC ram. I've had several events where after one drive failed, I discovered minor errors on a second drive...

Currently kernel raid can't use raid 6 to decide a majority win if a bit error is discovered. MD-integrity seems to cost a fair bit of performance (relative to zfs). So I like either plain LVM+raid 6 or also add an integrity option if I want to defend against bit rot.

It's simple to operate. Loads of experts available if it breaks. Well tested. easy to expand or even drastically reshape.

It lacks "send". and performance of snapshots could be lower (try thin pools). Can easily add SSD caching, but performance improvement is possibly not as high as with alternatives

works well enough for me...
