Yes, I'm using ZFS on laptop to get benefits of snapshotting and zfs
send/receive, apart from that the machine does not do heavy IO :)
Thanks for advice, definitely it is not a intended use scenario.
May some changes in documentation will help to provide better clarity.
Or may be even
ZFS already limits the amount of IO that a scrub can do. Putting
multiple pools on the same disk defeats ZFS's IO scheduler.* Scrubs are
just one example of the performance problems that will cause. I don't
think we should complicate the scrub script to accommodate this
scenario.
My suggestion is
I'm using it on laptop.
One pool holds OS + home directories and other more-or-less fast
changing stuff.
Another one holds only backups and VM images.
First reason was to try deduplication on VM dataset without affecting
main pool.
Second reason was to have two big partitions to do experiments
Why do you have multiple pools on the same disks? That's very much not a
best practice or even typical ZFS installation.
