Run SCRUB only inside specified time frame

[subscriber]

Hi


Is it possible to set schedule for scrub to run only in specified time frame like every day from 02:00h to 04:00h in the morning ?
Something like Synology offers ?
I know scrubs can be stopped. Does this mean the next scrub job starts from scratch or does it remember the state of the presvious scrub and takes it from where it left of ?

I have 51TB dataset and scrubs run for days which slows the whole system and is noisy.

Thanks in advance

I don't think it necessarily stops the scrub, but should stop you noticing performance impact.

You can also pause a scrub via zpool scrub -p <name of pool>, and resume when convenient with zpool scrub <name of pool>. Potentially, you could set up cron jobs to automate the suspend/resume.

Thank you both for tips, will use both of them to fine tune the scrubbing
