On: In Praise of ZFS on Linux's ZED 'ZFS Event Daemon'

[mapgrep]

Disagree that data integrity is “overkill for most home applications.”

[louwrentius → mapgrep]

Tell that to all those Mac, Linux and Windows users on their daily desktops and laptops.

Almost none of them have even ECC memory.

[theamk → louwrentius]

Memory has much fewer “moving parts” than disk. You cannot get bad “memory cable”, and (AFAIK) there are no cases when overloaded power supply caused memory errors,

[gnufx → theamk]

Obviously it's not connected by cable, but you certainly get the equivalent to cable errors, and I've been plagued by them on certain systems. It's revealing when you have a lot of systems with monitoring of ECC errors. I wouldn't like to say whether multiple DIMMs are necessarily more reliable even than rotating disks.

[louwrentius → theamk]

Memory in a regular desktop/laptop is basically the only part not protected by some kind of ECC algorithm.

If you care so much about data integrity, please start there.
