- Minor
This is a continuation of an older thread: see here. I updated to Unraid 7 and wanted to open a new ticket. Unraid seems like its functioning fine until suddenly it just suddenly drops off the network. It doesn't show up on my router or when I run arp-scan or anything. The only solution is to power cycle unraid via IPMI. This seems to be random and is not reproducible. There's two log files, so I'm attaching both.
I'm running a SuperMicro X9sri board with a Xeon E5-2620 and 64GB RAM. I'm not using a separate HBA, just the integrated SAS/SATA controller. It seems that the integrated Intel SAS controller on my Supermicro x9sci-f board is having a problem. It keeps spamming the OS with
Jan 7 18:00:00 Tower kernel: sas: Enter sas_scsi_recover_host busy: 1 failed: 1 Jan 7 18:00:00 Tower kernel: sas: ata7: end_device-1:0: cmd error handler Jan 7 18:00:00 Tower kernel: sas: ata7: end_device-1:0: dev error handler Jan 7 18:00:00 Tower kernel: sas: ata8: end_device-1:1: dev error handler
Others thought that perhaps it was the DVD drive so I moved some drives around, but this problem has continued to occur. As far as I can tell, it appears only to be the SAS ports (ata7 and ata8) that are effected. I'm running 2 WD Red Plus SATA drives on them, but this shouldn't be an issue (as far as I'm aware). These drives all pass SMART tests and get expected read/write speeds from Unraid. (~130 Mb/s reads while checking parity).
Is it possible the SAS controller is dying? Is there a BIOS setting I need to change?
Thanks!
