The output from dmesg is shown in the attached image.
(sorry for not sending text content, as I'm away of the server and a friend of mine is doing the stuff)
I'll check the other command result in the following post.

It follows the output of the command cat /proc/filesystems.

There seems to be an xfs file on the raid array. And xfs is supported in the kernel but with sector size if 512 bytes.
The question is now with what sector size did the lacie firmware formatted the array.
What does these commands tell us
Code: Select all
blkid /dev/md4
gdisk -l /dev/md4

It follows the outputs, where blkid did not produce any result.

mmm... the standalone kernel has a limited linux system. Probably lacie firmware used a blocksize of 4096 Bytes to format the xfs file system, need to check if support for sector size of 4096 Bytes can be added in the kernel

Ok, I'll wait for this check, hope that the new version could solve the issue.
Furthermore, a donation of 5 € was sent to you. Thanks for the advising.

ok thank you much appreciated

Lets first do some further investigation, I checked the standalone kernel it supports xfs file system with block size of 512 and 4096 Bytes (the normal values for linux kernels). I cannot believe the lacie firmware used another setting and even then also their kernel would be unable to mount it.
From the data you provided earlier I can see that sector size of the dile system is 512 Bytes :thumbup

please try this command(using the the busybox mount command instead of util-linux version)
Code: Select all
busybox mount -t xfs /dev/md4 /md4

oke
If you have performed the mount command also give this command
Code: Select all
dmesg | tail


In the outputs you posted earlier I see two things that are not normal
md4: unknown partition table

and with gdisk command indeed we do do not see a partion table.

Could be that we need to check if repair the xfs file system is required using xfs_repair

On a raid block device, it is the expected output. So on gdisk side it is ok. In my opinion we should use directly xfs_repair tool and what output it returns
