![]() Then I exit the shell and system boots fine. I am able to drop to a shell and manually attach the encrypted container with the command: bioctl -c C -l /dev/sd3a softraid0. The Issue When the system boots it obviously complains it can't find /var /usr /tmp etc. However, this final step would be of no good if a given physical drive has already been taken offline from the logical one, since there is no longer any way to mount it, or modify its content. The rest of the system is mounted on sd4 : /usr, /home, /tmp, /var etc. In the first case run chkdsk /f on Windows then reboot into Windows twice. ![]() Failed to mount /dev/sdb1: Input/output error NTFS is either inconsistent, or there is a hardware fault, or its a SoftRAID/FakeRAID hardware. The final alternative would seem to be to try to fill all filesystems with files full of /dev/zero, which may or may not make the logical drives have the same content, and then trying to do the comparison of the data on the physical drives with sha1 as in the step above. su - root mount /dev/sdb1 /media/user/sdb1 MFTMirr does not match MFT (record 0). This would make it possible to compare data block-by-block (for example, by mounting the filesystems in read-only mode, and doing a sha1 of each physical drive, after ignoring the initial offset that's used to store the softraid information (unless it's stored in multiple locations on disc, like the filesystems do with some most important data)). As I told OWC, I don’t think SoftRaid is ready for the M1. I’ve since used the SSDs in a single enclosure without SoftRaidworks fine. So I quit using the 4M2 enclosure/SoftRaid. There doesn't seem to be any code to this effect currently.Īnother alternative would be to completely zero-out all the physical drives prior to creating the softraid, or zero out out all the logical RAID volumes prior to creating the filesystems. To fix this error, you can use ntfsfix, a tiny and useful utility that fixes some common NTFS problems. I was uncomfortable with the discrepancy, and numerous exchanges with OWC could not correct the situation. However, since each filesystem on top of softraid is RAID-agnostic, there would have to be a special way to, perhaps, mount the filesystem in a read-only mode onto several different mounting points, with each mount being tied to a separate physical drive in the underlying RAID1, and then run a comparison tool to compare filesystem content between the drives. Is no point in wasting a lot of time syncing random data.Īs such, the integrity and consistency between the physical drives would have to be verified with the help of a filesystem. Is by design because all sectors that are read are written first. dev/mapper/nvidia_eahaabcc1).As the documentation for OpenBSD's softraid seems to indicate, the arrays are created without any kind of synchronisation taking place during the creation step: The RAID 1 discipline does not initialize the mirror upon creation. It and mount a different device under the /dev/mapper/ directory, (e.g. After updating to this new macOS release, the SoftRAID version 6 driver will load correctly, and you will be able to access your SoftRAID volumes. Important! If the device is a SoftRAID/FakeRAID then first activate UPDATE: ApWith the release of macOS 11.3 yesterday, Apple has now fixed the bug that prevented the SoftRAID driver from loading on M1 Macs. ![]() Its possible that these contain your filesystems you could try: mount /dev/md1 /mnt Or: mount /dev/md2 /mnt Depending on how your system is configured it is also possible that these devices are themselves part of a larger virtual device. ![]() In the first case run chkdsk /f on Windows Your RAID devices are called /dev/md1 and /dev/md2. NTFS is either inconsistent, or there is a hardware fault, or it's a SoftRAID Comes the M1 Macs Mr Screech macrumors regular 234 250 4 Realize that RAID enclosures with several spinning disks make a lot of noise. I am having trouble mounting my external hard drive, every time I try and do so I get the following message: "Error mounting /dev/sdb1 at /media/fuzzy27/My Book: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,dmask=0077,fmask=0177" "/dev/sdb1" "/media/fuzzy27/My Book"' exited with non-zero exit status 13: $MFTMirr does not match $MFT (record 0).įailed to mount '/dev/sdb1': Input/output error Second attempt, started from scratch and built a new Apple raid volume, tried the convert thing but sadly the result was the same, will not mount the volume.
