Hi,

 

I just recovered from a failed disk last week, where read errors had occurred on multiple disks until one drive "red balled" and could not be recovered. I was able to rebuild the drive and the server ran smoothly through a parity check without significant errors, but a few "program smartctl is using a deprecated SCSI ioctl, please convert it to SG_IO" messages.

 

A few days later I'm having read errors on two disks (disk 1 and disk 11) as well as hundreds of "program smartctl is using a deprecated SCSI ioctl, please convert it to SG_IO" messages and many "REISERFS error (device md1): zam-7001 reiserfs_find_entry: io error" type errors. All disks were still green, but since I was leaving for the weekend, so I decided to shut down the server in case things we south while I was away. However, after stopping the array, disk11 "red balled"

 

Am I the most unlucky person in the world that all of my disks are failing simultaneously or is something else going on? Thankfully I completed the disk3 rebuild before disk11 died!

 

I've attached the diagnostic zip file.

 

I am running Unraid 6.0.0 with 13 drives (5 on mobo, 8 on SUPERMICRO AOC-SASLP-MV8).

 

Thanks for the help.

Look like a bad or loose SATA connector, a dirty or bad SATA port, a bad or loose SATA HBA. Start with new SATA cables.

Thanks, I'll give that a try.
