Anyone ever seen this before? I have 4 servers, 2 old and 2 new, all run 6.5.2a, now 6.5.3 as of this morning. I see this error occur in the logs a few moments after midnight, every night. I did notice mt-st was not installed on the machines that were getting this error, so I installed that and we'll see if the issue recurs for tomorrow; however, was curious if anyone had seen this?
The first host has two directly-attached fiber drives: Jan 4 00:02:19 host1 kernel: st 0:0:0:0: reservation conflict Jan 5 00:01:19 host1 kernel: st 0:0:0:0: reservation conflict Jan 5 00:01:47 host1 kernel: st 1:0:0:0: reservation conflict Jan 6 00:01:18 host1 kernel: st 1:0:0:0: reservation conflict Jan 6 00:02:18 host1 kernel: st 0:0:0:0: reservation conflict Jan 7 00:01:18 host1 kernel: st 0:0:0:0: reservation conflict Jan 7 00:02:20 host1 kernel: st 1:0:0:0: reservation conflict The second host has one directly-attached fiber drive: Jan 1 00:00:45 host2 kernel: st 0:0:0:0: reservation conflict Jan 2 00:02:13 host2 kernel: st 0:0:0:0: reservation conflict Jan 3 00:00:44 host2 kernel: st 0:0:0:0: reservation conflict Jan 4 00:00:45 host2 kernel: st 0:0:0:0: reservation conflict Jan 5 00:00:45 host2 kernel: st 0:0:0:0: reservation conflict Jan 6 00:00:44 host2 kernel: st 0:0:0:0: reservation conflict Jan 7 00:00:44 host2 kernel: st 0:0:0:0: reservation conflict The two servers are setup identical for the most part as the other two with the exception noted above for sotware. For hardware they are using newer HBAs etc. However, in 6.5.x I also see the SCSI reservation option has changed: In 6.0MP7: Go to Master Server Properties -> Media [x] Enable SCSI reserve / release In 6.5.x: Go to Master Server Properties -> Media [x] Enable SCSI reserve (o) SPC-2 SCSI reserve ( ) SCSI Persistent reserve 1. Do you think the issue was caused by the absence of the mt-st package on the two hosts? 2. Or, are the two newer servers (with newer/different qlogic fiber cards), do they need a specific settings, perhaps SCSI Persistent reserve and not SPC-2 SCSI reserve?
