Worth noting: During a zfs resilver (as with any sort of RAID rebuild) your drives are continuously busy. So the vastly-longer CoW/SMR rebuild can be rather problematic on production systems. Best to know your workload, and make sure that you have an ironclad paper trail - showing how PHB ignored your repeated objections and warnings when he decided to save money by buying SMR disks.
- vermaden 2y agoTo be honest I would not expect using SMR drives in some important production systems. I would even prefer to use CMR ones ... but the 2.5 drives with 4-5 TB capacity are only available in SMR - maybe in the future when 2.5 drives will ofeer 8-10 TB of space - there would be a 4-5 TB CMD 2.5 drive.
