January 31, 20224 yr For a few months now my primary unraid server experiences seemingly random times when it becomes unresponsive. That is, SMB and NFS shares are inaccessible, VM's don't work, and I can not access the web GUI. I don't know for sure, but I believe it might be connected to a repeating log entry I keep getting: Jan 31 16:39:54 Tower kernel: sd 3:0:6:0: [sdh] tag#1347 Sense Key : 0x1 [current] Jan 31 16:39:54 Tower kernel: sd 3:0:6:0: [sdh] tag#1347 ASC=0x1c ASCQ=0x0 That's just from one disk, but all the disks get them and its absolutely unrelenting. Sometimes the server will run for weeks, though more often it will run for a few days before needing to be hard-reset. While I can't recall exactly, I know this started happening after I moved my server from an R410 to an R710. All of my drives are (and have been) SAS drives. After the upgrade, however, I did replace my SATA cache SSDs with LB806M SAS SSDs. Those are mounted in the actual R710 with the HDDs being mounted in an MD1000 external case. Diagnostics attached, and I would be happy to provide any other information needed. Side note, I don't know what it will show in diagnostics, but when downloaded, I was (am) running a parity check with Disk 3 missing. The drive was failing so I replaced a parity drive with a new 10Tb and once this parity check is done, the old 8Tb parity will go in Disk 3's place. There is also a UD that is 'unhealthy', but it's an old desktop drive I was pulling files off of, nothing related to the system as a whole. Just figured I would mention it. tower-diagnostics-20220131-1638.zip
March 27, 20233 yr Author Short answer, no. Long answer, no, but after a lot of searching, I think it might be related to something to do with either the SAS drives or the HBA. I only guess that because I can find some (limited) information on ASC and ASCQ "codes".. It's pretty lame though as these eventually fill up my log file and as far as I know the only way to clear that is a restart... Out of curiosity, what's your setup? Just wondering if there's any common denominator here...
