Thumbs down mount raid volumes - SnapServer

Good morning,

I'm trying to recover a raid5 set in a 4x1T Snapserver 410 through linux, due to hardware failure, but impossible to do so. I'm just trying to read (the best howto's about Snapservers) but it is still offline. Each disk is partitioned in the nextway:

Device Boot Start End Blocks Id System
/dev/sda1 * 47 32129 16041+ 83 Linux
/dev/sda2 32130 1124549 546210 83 Linux
/dev/sda3 1124550 2216969 546210 5 Extended
/dev/sda4 2216970 1953525167 975654099 83 Linux
/dev/sda5 1124551 1670759 273104+ 83 Linux
/dev/sda6 1670761 2216969 273104+ 83 Linux

The Guardian OS is installed in the first partitions, plus /dev/sdX4 (the biggest one, I thing the raid 5 set).

When doing

[root@livecd ~]# mdadm --assemble --scan
mdadm: device 3 in /dev/md/101_1 has wrong state in superblock, but /dev/sdc5 seems ok
mdadm: Failed to restore critical section for reshape, sorry.
Possibly you needed to specify the --backup-file
mdadm: Failed to restore critical section for reshape, sorry.
Possibly you needed to specify the --backup-file
mdadm: No arrays found in config file or automatically

I don't know how to mount this raidset, has no information at all. Indeed, over raid5 info, there is LVM.

I've found,0 in order to recover, but couldn't.

Does anybody knows how to deal with this??

Thanks in advance.
