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 recently looked at this... NetBSD's features (per
https://openzfs.github.io/openzfs-docs/Basic%20Concepts/Feature%20Flags.html#compatibility
) are the same as what's listed in my ZoL
/usr/share/zfs/compatibility.d/freebsd-11.0 file, and that file lists
the same features as /usr/share/zfs/compatibility.d/compat-2020 so you
should be good.
Interesting question and perspective. I've been using ZFS since about
FreeBSD 8. I've never lost a bit and it's so easy to manage. The only
issues I have ever experienced (many, many TB of files across dozens of
drives and controllers) were transferring between my Linux machines and
the FreeBSD machines. I would expect it to be similar to NetBSD and
FreeBSD or Linux. Those pesky features!!! The annoyance is that zfs
complains when you try to access a drive/or snapshot from one system on
another with different features. The good news is that it doesn't affect
the integrity of the original, the bad news is that it's a pain to get
it over on the new system. That said, it's always been the case that
I've been able to get the job done - usually mounting the drive/snapshot
with the incompatible feature read-only and zfs sending it to the
destination with the other set of features. But, in recent days, this
hasn't happened at all.
Full disclosure, I'm a big ZFS fan - been burned so many times by other
"filesystems" it's ludicrous. Let me count the ways that I've been saved
by zfs, well it's a big number :). Now, if I could easily do zfs on root
and bectl like on freebsd on netbsd or linux, that'd make my life
complete. I get tired of backing up when a sent snapshot is just as good
and ten times as easy...
