Hello,

 

For a few weeks I've been seeing errors scatter across all disks in my server.
These errors occur across all backplanes, cables, ports. They've reappeared following new configs, component replacements, etc.

 

If a new config is applied and no parity device declared, it seems that all disks will hum along without issue. 

 

However when a parity action is began, whether sync/rebuild/read, it is inevitable that before long a disk will encounter errors. And then another, and another, until the system pauses that parity action or I intervene to cancel it.

 

Until today when I installed an all new CPU _and_ motherboard. Kicked off a parity sync,
and, again, errors begin appearing on every disk.

 

I've replaced:
- Controller
- RAM
- Motherboard
- CPU

 

I've attached diagnostics captured immediately after cancelling that parity sync.

Some problem with the way your parity is partitioned or something like that.

RAID controllers are not recommended for many reasons, maybe this is one of them.

 

You will probably have to wait several hours for @JorgeB

It's after 1am in that time zone.

It's a Linux kernel issue with that controller's driver, it should be fine if you downgrade to v6.12.4, or wait for 6.12.7, which should be out next week.

Thank you for that information.

 

As this array has been without parity for some time now while I chased these errors, I opted for the downgrade to v6.12.4.

Parity sync is now at 76.7% without encountering a single error.
