What chassis is this? ----- Original Message ----- From: "Dr Josef Karthauser" <joe@karthauser.co.uk> To: <freebsd-fs@freebsd.org> Cc: <freebsd-stable@freebsd.org> Sent: Thursday, July 18, 2013 8:29 AM Subject: Drive failures with ada on FreeBSD-9.1, driver bug or wiring issue? Hi there, I'm scratching my head. I've just migrated to a super micro chassis and at the same time gone from FreeBSD 9.0 to 9.1-RELEASE. The machine in question is running a ZFS mirror configuration on two ada devices (with a 8gb gmirror carved out for swap). Since doing so I've been having strange drop outs on the drives; the just disappear from the bus like so: (ada2:ahcich2:0:0:0): removing device entry (aprobe0:ahcich2:0:0:0): NOP. ACB: 00 00 00 00 00 00 00 00 00 00 00 00 (aprobe0:ahcich2:0:0:0): CAM status: ATA Status Error (aprobe0:ahcich2:0:0:0): ATA status: d1 (BSY DRDY SERV ERR), error: 04 (ABRT ) (aprobe0:ahcich2:0:0:0): RES: d1 04 ff ff ff ff ff ff ff ff ff (aprobe0:ahcich2:0:0:0): Error 5, Retries exhausted (aprobe0:ahcich2:0:0:0): NOP. ACB: 00 00 00 00 00 00 00 00 00 00 00 00 (aprobe0:ahcich2:0:0:0): CAM status: ATA Status Error (aprobe0:ahcich2:0:0:0): ATA status: d1 (BSY DRDY SERV ERR), error: 04 (ABRT ) (aprobe0:ahcich2:0:0:0): RES: d1 04 ff ff ff ff ff ff ff ff ff (aprobe0:ahcich2:0:0:0): Error 5, Retries exhausted At first I though it was a failing drive - one of the drives did this, and I limped on a single drive for a week until I could get someone up to the rack to plug a third drive in. We resilvered the zpool onto the new device and ran with the failed drive still plugged in (but not responding to a reset on the ada bus with camcontrol) for a week or so. Then, the new drive dropped out in exactly the same way, followed in short order by the remaining original drive!!! After rebooting the machine, and observing all three drives probing and available, I resilvered the gmirror and zpool again on the two devices expected that I thought were reliable, but before the resilvering was completed the new drive dropped out again. I'm scratching my head now. I can't imagine that it's a wiring problem, as they are all on individual SATA buses and individually cabled. Smart isn't reporting an drive issues either…. :/ So, I'm wondering, is it a driver issuer with 9.1-RELEASE, if I upgrade to 9-RELENG would I expect that to resolve the problem? (Have there been any reported ada bus issuer reported since last December?) The hardware in question is: ahci0: <Intel Cougar Point AHCI SATA controller> port 0xf050-0xf057,0xf040-0xf043,0xf030-0xf037,0xf020-0xf023,0xf000-0xf01f mem 0xdfb02000-0xdfb027ff irq 19 at device 31.2 on pci0 ahci0: AHCI v1.30 with 6 3Gbps ports, Port Multiplier not supported ahcich0: <AHCI channel> at channel 0 on ahci0 ahcich1: <AHCI channel> at channel 1 on ahci0 ahcich2: <AHCI channel> at channel 2 on ahci0 ahcich3: <AHCI channel> at channel 3 on ahci0 ahcich4: <AHCI channel> at channel 4 on ahci0 ahcich5: <AHCI channel> at channel 5 on ahci0 ada0 at ahcich0 bus 0 scbus0 target 0 lun 0 ada0: <WDC WD1000FYPS-01ZKB0 02.01B01> ATA-8 SATA 2.x device ada0: 300.000MB/s transfers (SATA 2.x, UDMA6, PIO 8192bytes) ada0: Command Queueing enabled ada0: 953869MB (1953525168 512 byte sectors: 16H 63S/T 16383C) ada0: Previously was known as ad4 ada1 at ahcich1 bus 0 scbus1 target 0 lun 0 ada1: <WDC WD1000FYPS-01ZKB0 02.01B01> ATA-8 SATA 2.x device ada1: 300.000MB/s transfers (SATA 2.x, UDMA6, PIO 8192bytes) ada1: Command Queueing enabled ada1: 953869MB (1953525168 512 byte sectors: 16H 63S/T 16383C) ada1: Previously was known as ad6 ada2 at ahcich2 bus 0 scbus2 target 0 lun 0 ada2: <WDC WD1000FYPS-01ZKB0 02.01B01> ATA-8 SATA 2.x device ada2: 300.000MB/s transfers (SATA 2.x, UDMA6, PIO 8192bytes) ada2: Command Queueing enabled ada2: 953869MB (1953525168 512 byte sectors: 16H 63S/T 16383C) ada2: Previously was known as ad8 Any ideas would be greatly welcomed.
