Lots of errors, is my controller failing?

Been running the same hardware for a long time now.  Started getting errors on all drives.  Shut down and did a fresh boot.  Here's the complete syslog.  Is my AOC-SAS2LP-MV8 failing??

It looks like most of the errors are relating to ST3500630AS, (your cache drive).

 

I'm seeing three different things here:

 

1 - ata11.00: failed command: READ FPDMA QUEUED

 

These errors are usually (but not necessarily always) related to bad / loose cabling and/or power to the drive

 

2 - ata11.00: device reported invalid CHS sector 0

 

This could be a bad drive, but the only time I've ever seen it on one of my drives, it always went hand in hand with #1 and was narrowed down to a cabling issue

 

3 - BTRFS info (device sdh1): no csum found for inode 2928556 start 662118400

 

Looks like the file system on your cache is corrupted.  Possibly caused by cabling

 

 

You could have a bad drive, or a bad port but right now initially, I would go with bad or loose sas cables or a power problem (weak supply, too many splitters, etc)

 

If you're using hotswap bays, I would also definitely reseat the caddy

 

After you fix the hardware issues, then I would run a scrub on the drive

Running a corsair 750 watt power supply with not splitters.

 

Gonna go swap out my 8087 SAS cables and see if that does the trick

Just noticed that you've got an issue with ata12.00: ATA-8: ST3000DM001-1CH166,            Z1F2XP1C.

 

ata12.00: failed to IDENTIFY (I/O error, err_mask=0x4)  Probably the same cabling issue.

 

Once we get rid of those hardware errors (1 & 2), then you can deal with the scrub (and/or save everything on the cache and reformat it)
