I can reproduce the "tags problem", RELENG_4 built today. Also noticed some weird secondary IDE stuff. Are there any ATA patches I don't know about? Is it worth trying CURRENT? Will do anything (legal) to help solve the problem. I've borrowed the box for the weekend, so fire away. Three IBM-DTLA-307075 rescued from backup duties plus one new IC35L080AVVA07-0. [shown with tags off here] ad0: 78533MB <IC35L080AVVA07-0> [159560/16/63] at ata0-master UDMA100 ad1: 73308MB <IBM-DTLA-307075> [148945/16/63] at ata0-slave UDMA100 ad2: 73308MB <IBM-DTLA-307075> [148945/16/63] at ata1-master UDMA100 ad3: 73308MB <IBM-DTLA-307075> [148945/16/63] at ata1-slave UDMA100 First tried a LEX BN630LT M/B. Installed 4.6-RELEASE, upgraded to STABLE. Set up vinum RAID10 volume. While formating I had systat -vmstat running. Noticed that while the "load" appeared the same on all four disks, ad0 and ad1 were at ~5% busy, ad2 and ad3 were at ~50% busy. I posted somthing similar before (20010807). I've swapped the cables around, same result. Tried different cables, same result. All cables are spec length, don't have any shorter. This is a new board - could be a design fault. So I tried a recent gigabyte board, same result. Set tags on. As soon as I load the vinum volume I get [snip time /kernel] ad2: READ command timeout tag=0 serv=0 - resetting ad2: invalidating queued requests ad2: timeout waiting for cmd=00 s=d0 e=04 ad2: flush queue failed ata1: resetting devices .. ad2: invalidating queued requests ad2: DMA limited to UDMA33, non-ATA66 cable or device ad3: invalidating queued requests done ad2: no request for tag=0 ad2: invalidating queued requests So far only ad2 and ad3 fail. A thought occurs. There could be a master/slave problem with the firmware in the DTLA drives, which is fixed in the IC35. I'll swap the IDE cables on the M/B and see what happens. Maybe I'd better sleep first, I'm rambling. BTW, this is NOT a vinum problem. I get the same problem on normal volumes (but only on ad2 ad3). This is just a *neat* way of loading the drives. -- ian j hart To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
