Indicative of single bit errors in the superblock i.e. the "in progress flag is set, which is only set during mkfs and is zero at all other times. You could probably clear that field using xfs_db, but it's likely there are lots of other problems with the disk... > DISK 2: > [57949.398186] usb 2-1.2.4: new high-speed USB device number 16 using ehci-pci > [57949.519158] usb 2-1.2.4: New USB device found, idVendor=13fd, idProduct=0840 > [57949.519160] usb 2-1.2.4: New USB device strings: Mfr=1, Product=2, SerialNumber=3 > [57949.519161] usb 2-1.2.4: Product: External > [57949.519161] usb 2-1.2.4: Manufacturer: Generic > [57949.519162] usb 2-1.2.4: SerialNumber: [elided] > [57949.519441] usb-storage 2-1.2.4:1.0: USB Mass Storage device detected > [57949.519883] scsi host4: usb-storage 2-1.2.4:1.0 > [57950.522787] scsi 4:0:0:0: Direct-Access Generic External 1.14 PQ: 0 ANSI: 4 > [57950.523080] sd 4:0:0:0: Attached scsi generic sg2 type 0 > [57950.523790] sd 4:0:0:0: [sdc] 234441647 512-byte logical blocks: (120 GB/112 GiB) > [57950.524526] sd 4:0:0:0: [sdc] Write Protect is off > [57950.524528] sd 4:0:0:0: [sdc] Mode Sense: 23 00 00 00 > [57950.525248] sd 4:0:0:0: [sdc] No Caching mode page found > [57950.525251] sd 4:0:0:0: [sdc] Assuming drive cache: write through > [57950.573656] sdc: sdc1 > [57950.573659] sdc: p1 size 234439600 extends beyond EOD, enabling native capacity > [57950.578529] sdc: sdc1 > [57950.578530] sdc: p1 size 234439600 extends beyond EOD, truncated The partition table indicates that partition 1 extends past the end of the disk. > [57950.580963] sd 4:0:0:0: [sdc] Attached SCSI disk > [57950.913655] sd 4:0:0:0: [sdc] tag#0 FAILED Result: hostbyte=DID_ERROR driverbyte=DRIVER_SENSE > [57950.913658] sd 4:0:0:0: [sdc] tag#0 Sense Key : Hardware Error [current] [descriptor] > [57950.913659] sd 4:0:0:0: [sdc] tag#0 Add.

At this point, I suspect your problems are the USB enclosure your are using. Plug the disks directly into a SATA port and see if that makes the IO errors go away. This looks like hardware problems, not XFS issues... Cheers, Dave. -- Dave Chinner david@xxxxxxxxxxxxx
