S.M.A.R.T: Status: Failing

[Telos]

Any preferred diagnostic

Use OEM tools.

Confirming if something happens where the drive needs to be reformatted or replaced, a restore from hyper drive should have me back to latest backup time?

Hyper Backup does not support bare metal recovery.

Need to take right steps to prevent a complete rebuild.

WILL TRY OEM repair first…

Noticed a power failure status message though that has happened before and was never a thing

Yes, there was a power interruption, and, power interruptions in the past which never posed (known) issues.

Also, going forward buy a UPS for your NAS; it looks likely that this situation was caused in the first place by a power outtage.

Is the nas still running but just has disk warnings on it? If so replace one disk at a time with a brand new disk and it’ll rebuild.

I think fortran hit the nail on the head, no NAS is pampered without UPS attached

NAS is up and running. New drives just arrived. Have hyper backup running, and not recalling the name for the Synology configuration file. Even with that and the online tutorials, concerned that by the end of this I will be struck rebuilding everything from scratch.

Appreciate the mention of installing one drive at a time and it will rebuild. That is the best case scenario. No concern around blocks/sectors/data getting transferred to new drive?

Update:

Drives have been replaced. Didn’t expect each drive rebuild to take 24-30 hours. When both were complete, got error where a scrub seemed to have done the trick.

A few additional questions surfaced which I will create a separate post to keep the topics separated.

Overall it appears everything has been fixed and running as before, however healthy status messages.

Thank you for the input and support.

Before replacing a failing (or good) drive (not, failed drive) in SHR, always scrub to ensure your data integrity. After you have removed a drive, there is no means to truly repair data integrity as you no longer have dual copy capability
