They did mention ZFS, so verified hashes of each file block. I hope they are scrubbing, and have at least one snapshot.

- mmh0000 2y agoZFS does nothing to protect you against RAM corrupting your data before ZFS sees it. All you'll end up with is a valid checksum of the now bad data. You can Google more, but, I'll just leave this from the first page of the openZFS manual: Misinformation has been circulated that ZFS data integrity features are somehow worse than those of other filesystems when ECC RAM is not used. This is not the case: all software needs ECC RAM for reliable operation and ZFS is no different from any other filesystem in that regard.[1] [1] https://openzfs.readthedocs.io/en/latest/introduction.html https://openzfs.readthedocs.io/en/latest/introduction.html
- mafro 2y agoWhy would one snapshot help?
- ratboy666 2y agoOne snapshot would help because, if EVERYTHING collapses, and you need data recovery, the snapshot provides a basepoint for the recovery. This should allow better recovery of metadata. Not that this should EVER happen -- it is just a good idea. I use Jim Salter's syncoid/sanoid to make snapshots, age them out, and send data to another pool. I agree that ECC is a damn good idea - I use it on my home server. But, my lappy (i5 thinkpad) doesn't have it.
