I suspect this problem has little to do with RAID, but since I'm using it I thought I'd start here. I have 3 disks in a Vantec HX4 4 SATA drive box, connected by USB. Repeatedly, when I try to read certain sectors of one disk every disk in the box seems to reset and then get remounted. I thought this was a transient power failure the first time (though I'm on UPS), but when it happened again I figured the problem was elsewhere. I am surprised that a read failure on one drive seems to reset the entire connection to the box. The disk is a relatively new WD Red Pro, and so seems unlikely to have a physical failure. The Vantec box is almost 5 years old, and seems a better suspect. The only reason I can think that reading a particular spot on one disk would make it fail is that this is perhaps accompanied by some other activity at the same time. The Vantec itself supplies no RAID or anything fancy, just access to the drives. The setup is only nominally RAID1, since I have yet to add a spare drive for either array in use. It looks as if the RAID arrays survive the redefinition of the physical devices (e.g., sde is reattached as sdj), but it's hard to tell since the partition with the error is mounted read-only and thus generates errors. I have been rebooting the whole system shortly after the problem happens. Should the /dev/md* devices survive such remapping beneath them? After the remapping the file systems the md devices supported on the host computer were still mounted (albeit ro for one of them). mdadm -D did not llist the names of the component devices and the info in proc (or maybe it was run) seemed stale, since it still had the old device names (e.g., sde3 rather than sdj3). Linux Kernel 3.16. Hmm, these problems are occurring a day after a security upgrade of the kernel: [UPGRADE] linux-image-3.16.0-0.bpo.4-amd64:amd64 3.16.36-1+deb8u2~bpo70+1 -> 3.16.39-1~bpo70+1 There is a very long list of changes between those versions: http://ftp-master.metadata.debian.org/changelogs//main/l/linux/linux_3.16.39-1~bpo70+1_changelog Here's the kern.log entries from the event start: Jan 24 15:22:59 tempserver kernel: [96418.113742] usb 2-4: USB disconnect, device number 3 Jan 24 15:22:59 tempserver kernel: [96418.117141] scsi 7:0:0:2: rejecting I/O to offline device Jan 24 15:22:59 tempserver kernel: [96418.117149] scsi 7:0:0:2: [sde] killing request Jan 24 15:22:59 tempserver kernel: [96418.117172] scsi 7:0:0:2: [sde] Unhandled error code Jan 24 15:22:59 tempserver kernel: [96418.117174] scsi 7:0:0:2: [sde] Jan 24 15:22:59 tempserver kernel: [96418.117175] Result: hostbyte=DID_NO_CONNECT driverbyte=DRIVER_OK Jan 24 15:22:59 tempserver kernel: [96418.117177] scsi 7:0:0:2: [sde] CDB: Jan 24 15:22:59 tempserver kernel: [96418.117178] Read(16): 88 40 00 00 00 01 93 d9 41 a8 00 00 00 f0 00 00 Jan 24 15:22:59 tempserver kernel: [96418.117188] end_request: I/O error, dev sde, sector 6775456168 # 2nd time it was 6775455984 Jan 24 15:22:59 tempserver kernel: [96418.117202] scsi 7:0:0:2: rejecting I/O to offline device Jan 24 15:22:59 tempserver kernel: [96418.117205] scsi 7:0:0:2: [sde] killing request Jan 24 15:22:59 tempserver kernel: [96418.117208] scsi 7:0:0:2: [sde] Unhandled error code Jan 24 15:22:59 tempserver kernel: [96418.117210] scsi 7:0:0:2: [sde] Jan 24 15:22:59 tempserver kernel: [96418.117211] Result: hostbyte=DID_NO_CONNECT driverbyte=DRIVER_OK Jan 24 15:22:59 tempserver kernel: [96418.117212] scsi 7:0:0:2: [sde] CDB: Jan 24 15:22:59 tempserver kernel: [96418.117213] Read(16): 88 00 00 00 00 01 93 d9 42 98 00 00 00 20 00 00 Jan 24 15:22:59 tempserver kernel: [96418.117220] end_request: I/O error, dev sde, sector 6775456408 Jan 24 15:23:01 tempserver kernel: [96419.765989] usb 2-4: new SuperSpeed USB device number 4 using xhci_hcd Jan 24 15:23:01 tempserver kernel: [96419.782952] usb 2-4: New USB device found, idVendor=152d, idProduct=0551 Jan 24 15:23:01 tempserver kernel: [96419.782955] usb 2-4: New USB device strings: Mfr=1, Product=2, SerialNumber=5 Jan 24 15:23:01 tempserver kernel: [96419.782957] usb 2-4: Product: USB to ATA/ATAPI Bridge Jan 24 15:23:01 tempserver kernel: [96419.782958] usb 2-4: Manufacturer: JMicron Jan 24 15:23:01 tempserver kernel: [96419.782958] usb 2-4: SerialNumber: DA00862620FF Jan 24 15:23:01 tempserver kernel: [96419.785081] usb-storage 2-4:1.0: USB Mass Storage device detected Jan 24 15:23:01 tempserver kernel: [96419.785189] scsi8 : usb-storage 2-4:1.0 Jan 24 15:23:02 tempserver kernel: [96420.783801] scsi 8:0:0:0: Direct-Access WDC WD20 01FASS-00W2B0 PQ: 0 ANSI: 2 CCS Jan 24 15:23:02 tempserver kernel: [96420.784024] scsi 8:0:0:1: Direct-Access WDC WD20 EARS-00MVWB0 PQ: 0 ANSI: 2 CCS Jan 24 15:23:02 tempserver kernel: [96420.784240] scsi 8:0:0:2: Direct-Access WDC WD40 01FFSX-68JNUN0 PQ: 0 ANSI: 2 CCS The original read error seems to be in sde3, which is md/media3 aka md127 (see partition map below). But there are subsequent failures on md126 aka media4. The writes originate from VirtualBox which stores control info on media3 and has virtual disks on media3 and media4 (AFAIK this is all via regular files--the virtual disks are simply files on the host OS). Here's the rest of the log, and then a bunch of diagnostic info on my system. I'm not sure if attachments are OK, so this is all inline. Thanks for any help you can offer.
