The workaround I found was to mount the drive, unmount it and remount it all changes made during the second mount session would then persist. I found the exact same behaviour if I used the rw+ option instead of force. I am assuming that the cause of this behaviour is the stil-buggy read-write support in fuse-ext2. However upon reattachment to a linux system (the WD NAS drive running busybox) I would find that my changes had been mysteriously reverted or, on a couple of occasions, the edited file would be truncated. I could unmount, remount and find my changes still present. The drive mounted normally and I could edit files. I chose Ignore, then issued the following fuse-ext2 command to mount the partition of interest:įuse-ext2 /dev/disk1s1 /Volumes/nas -o force This seems reasonable given that no partition on the drive is supported by OS X out of the box. linux command-line ubuntu-server kill mv Share Improve this question Follow edited at 21:38 asked at 21:14 Jayden Lawson 123 7 1 I think you need a reboot of the OS. On connection to USB, I'd see a warning message that the drive was not readable and an offer to Initialise or Ignore. The fuse-ext2 command is the one taking all the CPU's resources. Fuse-ext2 requires at least Fuse for macOS version 2.7.5 or greater. Dependencies Fuse-ext2 requires at least Fuse version 2.6.0 for Linux. Using the pre-requisite 32 bit kernel, MacFUSE 2.0.3 and fuse-ext2 0.0.7, I found the following behaviour. Fuse-ext2 is an EXT2/EXT3/EXT4 filesystem for FUSE, and is built to work with osxfuse. (you'll probably need to apt-get fuseext2 first. using fuse-ext2 to mount the disk: fuseext2 -o ro -o syncread /dev/sdb4 /mnt/. My question is, what symbol should I be searching for in my kernel config to allow bigger block sized partitions to be mounted? I've scoured google for this, and I thought I saw the option before but I can't find any mention of it in the latest stable kernel source.So I have a 1TB drive with four partitions, only two of which were ext (both ext3 journaled) and the other two were 'not recognised' (the drive was from a Western Digital MyBook World Edition NAS drive). The short answer is you can't mount >4k block size devices on x86 linux machines as far as I can tell without some serious kernel hacking. As far as I can tell my kernel isn't configured to support block sizes of over 4K. In some cases useful info is found in syslog - tryĭmesg output: EXT4-fs (sdb4): bad block size 65536 Missing codepage or helper program, or other error Then i changed the name back to the original umlaut variant and was still able to access the files. But since it has real 'read and write' support i was able to change the file names and bring them back to life. This wasn't either able to read my files with the Umlauts. Download and install FUSE-Ext2 as described here and then run something like mkdir /Volumes/Linux sudo mount -t fuse-ext2 /dev/disk2s6 /Volumes/Linux You can figure out the device from looking at the output of diskutil list. Mount: wrong fs type, bad option, bad superblock on /dev/sdb4, First I uninstalled fuse-ext2 and installed the Paragon ExtFS Driver. So I'm trying to access partition 4 (the big one!): mount -t ext4 /dev/sdb4 /mnt/ Number Start End Size File system Name Flags Copied Change the file system type to ext2 by typing the following command: Copy. Sector size (logical/physical): 512B/4096B Unmount the partition by logging in as root and typing: Copy. morleys funerals live stream Command (m for help): Create a new (dos) partition table: press o and enter. The partition table is as follows: Model: ATA WDC WD30EZRS-11J (scsi) I chose Ignore, then issued the following fuse-ext2 command to mount the partition of interest: fuse-ext2 /dev/disk1s1 /Volumes/nas -o force The drive mounted normally and I could edit files. First make sure the drive is actually connected. I have a 3TB hard disk pulled out of a WD Mybook Live NAS.
