Failed to mount error on Raid 5

Greetings,

I'm running .5.48 with a usb external hard drive. After the install, I loaded 3x4TB hard drives from my old raid 5 that was also part of OMV. I wiped those drives doing a quick wipe and then built the raid. Now, when I try to mount the raid, i get this:

Error #6000:
exception 'OMVException' with message 'Failed to mount '5144add1-94fd-4eff-8c54-23ca6309ec05': ' in /usr/share/openmediavault/engined/rpc/filesystemmgmt.inc:873
Stack trace:

#3 /usr/sbin/omv-engined(495): OMVRpc::exec('FileSystemMgmt', 'mount', Array, Array, 1)
#4 {main}

Also noticed that the OS disk is now mounted as dev/SDD.

I've seen other posts for this but no real solution. Does anyone have an idea why this is happening and the fix?

First part of error message:
Failed to mount '5144add1-94fd-4eff-8c54-23ca6309ec05':

When I try to force mount:
Vault:~# mount -a /dev/md127
mount: wrong fs type, bad option, bad superblock on /dev/md127,

In some cases useful info is found in syslog - try
dmesg | tail or so

As you requested:

The same hard drive from a previous omv install using the same external usb case.

Nope... not smart enough to do that!

This is what I get:

mkdir /mnt/test101 && mount -t ext4 /dev/md127 /mnt/test101

fsck.ext4 /dev/md127 produces:

Error reading block 1953529856 (Invalid argument). Ignore error<y>? cancelled!

UltraNAS: Invalid argument while reading block 1953529856

Zitat von davidh2k

Are you sure its a ext4 filesystem?

I double checked in the gui under the filesystem

Neither command asked me to force a rewrite. If you want me to do so, how can I do that?
