One other data point and I'll leave it unless anything else turns up: I switched the two drives in the dock and got this from dmesg: [Tue Jun 22 10:52:03 2021] usb 4-3: USB disconnect, device number 2 [Tue Jun 22 10:52:03 2021] sd 6:0:0:0: [sdd] Synchronizing SCSI cache [Tue Jun 22 10:52:03 2021] sd 6:0:0:0: [sdd] Synchronize Cache(10) failed: Result: hostbyte=DID_ERROR driverbyte=DRIVER_OK [Tue Jun 22 10:52:03 2021] sd 6:0:0:1: [sde] Synchronizing SCSI cache [Tue Jun 22 10:52:03 2021] sd 6:0:0:1: [sde] Synchronize Cache(10) failed: Result: hostbyte=DID_ERROR driverbyte=DRIVER_OK [Tue Jun 22 10:52:27 2021] usb 4-3: new SuperSpeed Gen 1 USB device number 4 using xhci_hcd [Tue Jun 22 10:52:27 2021] usb 4-3: New USB device found, idVendor=174c, idProduct=55aa, bcdDevice= 1.00 [Tue Jun 22 10:52:27 2021] usb 4-3: New USB device strings: Mfr=2, Product=3, SerialNumber=1 [Tue Jun 22 10:52:27 2021] usb 4-3: Product: ASM1156-PM [Tue Jun 22 10:52:27 2021] usb 4-3: Manufacturer: ASMT [Tue Jun 22 10:52:27 2021] usb 4-3: SerialNumber: 00000000000000000000 [Tue Jun 22 10:52:27 2021] scsi host6: uas [Tue Jun 22 10:52:27 2021] scsi 6:0:0:0: Direct-Access ASMT ASM1156-PM 0 PQ: 0 ANSI: 6 [Tue Jun 22 10:52:28 2021] scsi 6:0:0:1: Direct-Access ASMT ASM1156-PM 0 PQ: 0 ANSI: 6 [Tue Jun 22 10:52:28 2021] sd 6:0:0:0: Attached scsi generic sg4 type 0 [Tue Jun 22 10:52:28 2021] sd 6:0:0:1: Attached scsi generic sg5 type 0 [Tue Jun 22 10:52:28 2021] sd 6:0:0:0: [sdd] 1953525168 512-byte logical blocks: (1.00 TB/932 GiB) [Tue Jun 22 10:52:28 2021] sd 6:0:0:0: [sdd] 4096-byte physical blocks [Tue Jun 22 10:52:28 2021] sd 6:0:0:0: [sdd] Write Protect is off [Tue Jun 22 10:52:28 2021] sd 6:0:0:0: [sdd] Mode Sense: 43 00 00 00 [Tue Jun 22 10:52:28 2021] sd 6:0:0:1: [sde] 1953525168 512-byte logical blocks: (1.00 TB/932 GiB) [Tue Jun 22 10:52:28 2021] sd 6:0:0:1: [sde] 4096-byte physical blocks [Tue Jun 22 10:52:28 2021] sd 6:0:0:0: [sdd] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA [Tue Jun 22 10:52:28 2021] sd 6:0:0:1: [sde] Write Protect is off [Tue Jun 22 10:52:28 2021] sd 6:0:0:1: [sde] Mode Sense: 43 00 00 00 [Tue Jun 22 10:52:28 2021] sd 6:0:0:0: [sdd] Optimal transfer size 33553920 bytes not a multiple of physical block size (4096 bytes) [Tue Jun 22 10:52:28 2021] sd 6:0:0:0: [sdd] Attached SCSI disk [Tue Jun 22 10:52:58 2021] sd 6:0:0:1: tag#26 uas_eh_abort_handler 0 uas-tag 2 inflight: IN <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<*** [Tue Jun 22 10:52:58 2021] sd 6:0:0:1: tag#26 CDB: Mode Sense(6) 1a 00 08 00 04 00 [Tue Jun 22 10:52:58 2021] scsi host6: uas_eh_device_reset_handler start [Tue Jun 22 10:52:58 2021] usb 4-3: reset SuperSpeed Gen 1 USB device number 4 using xhci_hcd [Tue Jun 22 10:52:58 2021] scsi host6: uas_eh_device_reset_handler success [Tue Jun 22 10:52:58 2021] sd 6:0:0:1: [sde] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA [Tue Jun 22 10:52:58 2021] sd 6:0:0:1: [sde] Optimal transfer size 33553920 bytes not a multiple of physical block size (4096 bytes) [Tue Jun 22 10:52:58 2021] sd 6:0:0:1: [sde] Attached SCSI disk The uas message is again from device 6:0:0:1 as before, even though the disks have been swapped. IOW the issue definitely comes from the dock, not from the physical drives themselves. Thanks again. poc _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
