Re: Need advice on ZFS

Hello,

I use ZFS on my NetBSD 10 server for a while to store all my family 
member's data and have never met any problem or data loss. I even 
managed to hack SSD caching into it - the NetBSD version doesn't seem to 
support cache files, only (SSD) disks, but with vnd0 (and a bit 
modification to /etc/rc.d/zfs) it is possible:

NAME        STATE
storage     ONLINE
   mirror-0  ONLINE
     wd0       ONLINE
     wd1       ONLINE
   cache
     vnd0      ONLINE

The wd disks are 4TB IronWolves - the server's 8Gb of memory is more 
than enough for this volume (without deduplication, of course).

Warm regards:

J.

Should I trust NetBSD's ZFS with my user's data?

I understand that our ZFS isn't being kept up as well as FreeBSD's,
that's why I have FreeBSD on one box on my home network, but I'd like
to keep all *my* hosts on NetBSD (my users run Windows). I have one
user (my wife) who has over 5 Terabytes of stuff she's very protective
of, but relies on me to protect it.

When I set up the file server I specified compatibility=2020. Would our
ZFS understand that?

I had bad experiences with zfs cache on SSD/nvme it crashes with time
once it corrupt the dataset so bad that took days to recover using
zpool import -fF -X .... ironwolfs are good but not as reliable as
WDC RED... I had some craches during power surge.. fortunately
there were 2 using mirror
