On one of the pools, I started a scrub. It never finishes. At one time,
I saw it go up to like 70% and then a little bit later I ran the pool
status, it went back to 5% and started again.
What is going on? Here is the pool layout:
pool: data2
state: ONLINE
scrub: scrub in progress, 35.25% done, 0h54m to go
config:
NAME STATE READ WRITE CKSUM
data2 ONLINE 0 0 0
mirror ONLINE 0 0 0
c0t12d0 ONLINE 0 0 0
c0t13d0 ONLINE 0 0 0
mirror ONLINE 0 0 0
c0t15d0 ONLINE 0 0 0
c0t16d0 ONLINE 0 0 0
errors: No known data errors
Thanks

Here is the pool layout:Initiating a snapshot stops the scrub. I don''t know if the scrub is restarted at 0%, or simply aborted. Are you taking snapshots during the scrub? Bob
Oh, my hunch was right. Yup, I do have an hourly snapshot going. I''ll take it out and see. Thanks!

ZFS co-inventor Matt Ahrens recently fixed this: 6343667 scrub/resilver has to start over when a snapshot is taken Trust me when I tell you that solving this correctly was much harder than you might expect.
