November 3, 20241 yr I happened to check the status of my cache pool, which are 2x 500GB SSD in a mirror. To my surprise I found that it had discovered a few errors. pool: cache state: ONLINE status: One or more devices has experienced an unrecoverable error. An attempt was made to correct the error. Applications are unaffected. action: Determine if the device needs to be replaced, and clear the errors using 'zpool clear' or replace the device with 'zpool replace'. see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-9P scan: scrub repaired 384K in 00:33:09 with 0 errors on Fri Nov 1 12:33:14 2024 config: NAME STATE READ WRITE CKSUM cache ONLINE 0 0 0 mirror-0 ONLINE 0 0 0 /dev/nvme0n1p1 ONLINE 3 0 0 /dev/sde1 ONLINE 0 0 0 errors: No known data errors I'm reading this as nvme0n1p1 had read errors, but the data was repaired due to the same bits being available on the other device in the mirror. If I clear the errors and don't see new ones, there is no reason to replace the disk? Why wasn't there a notification sent? I have enabled notification in Browser and Agents for all three notification levels. As you might notice the pool consists of one NVMe and one SATA SSD. I'm planning to replace them with two larger NVMe drives. What's the best method for doing that? replace one by one? will the usable space automatically expand? Edited November 3, 20241 yr by Ademar
