Bug ID: 214479 Summary: Cannot create or mount ext2 file system on a USB external drive Product: Base System Version: 11.0-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: usb Assignee: freebsd-usb@FreeBSD.org Reporter: giorgiox...@hotmail.com CC: freebsd-am...@freebsd.org CC: freebsd-am...@freebsd.org I have two external 1T USB drives which I use for backups. Both contain one MBR partition which is formatted with ext2fs. I can mount and use the first drive under FreeBSD without any problems. On the second drive, I cannot mount the ext2fs. Here is the model of the drive: # smartctl -i /dev/da1 smartctl 6.5 2016-05-07 r4318 [FreeBSD 11.0-RELEASE-p1 amd64] (local build) Copyright (C) 2002-16, Bruce Allen, Christian Franke, www.smartmontools.org === START OF INFORMATION SECTION === Model Family: Western Digital Blue Mobile Device Model: WDC WD10JPVX-00JC3T0 Serial Number: WD-WXQ1E945D4NJ LU WWN Device Id: 5 0014ee 65add21b2 Firmware Version: 01.01A01 User Capacity: 1,000,204,886,016 bytes [1.00 TB] Sector Sizes: 512 bytes logical, 4096 bytes physical Rotation Rate: 5400 rpm Device is: In smartctl database [for details use: -P show] ATA Version is: ACS-2 (minor revision not indicated) SATA Version is: SATA 3.0, 6.0 Gb/s (current: 3.0 Gb/s) Local Time is: Sat Nov 12 11:53:56 2016 CET SMART support is: Available - device has SMART capability. SMART support is: Enabled I have scanned the drive for bad sectors and nothing was found. I have partitioned and formatted with ext2fs under GNU/Linux: GNU/Linux can mount and use the drive. Under FreeBSD I get the following errors: # mount -t ext2fs /dev/da1s1 mnt mount: /dev/da1s1: Invalid argument If I try to check the file system I get the following error: # fsck_ext2fs -f -n -v /dev/da1s1 e2fsck 1.42.13 (17-May-2015) /sbin/e2fsck: Attempt to read block from filesystem resulted in short read while trying to open /dev/da1s1 Could this be a zero-length partition? I have also partitioned the drive under FreeBSD using gpart and formatted with ufs, and everything seems to work OK: I can mount, write files, read files. I have tried formatting with ext2fs from FreeBSD and got warnings: # mke2fs /dev/da1s1 mke2fs 1.42.13 (17-May-2015) /dev/da1s1 contains a ext2 file system Proceed anyway? (y,n) y Warning: could not erase sector 2: Attempt to write block to filesystem resulted in short write Creating filesystem with 244188598 4k blocks and 61054976 inodes Filesystem UUID: 22101a6d-fda0-4bfb-98a2-353b27953c13 Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 4096000, 7962624, 11239424, 20480000, 23887872, 71663616, 78675968, 102400000, 214990848 Allocating group tables: done Warning: could not read block 0: Attempt to read block from filesystem resulted in short read Warning: could not erase sector 0: Attempt to write block to filesystem resulted in short write Writing inode tables: done Writing superblocks and filesystem accounting information: 0/7453 If I check the filesystem from FreeBSD I get the same errors: /sbin/e2fsck -f -n /dev/da1s1 e2fsck 1.42.13 (17-May-2015) /sbin/e2fsck: Attempt to read block from filesystem resulted in short read while trying to open /dev/da1s1 Could this be a zero-length partition? So, I have these problems only with this disk and only with ext2fs. One thing that occurred to me, is that GNU/Linux reports a physical sector size of 2048 bytes while for the other working disk it reports a physical sector size of 512. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-usb@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "freebsd-usb-unsubscr...@freebsd.org"
