    Yeah, the forum software doesn't handle dashes correctly.

     

    Thx for the update.  It looks like there was no file corrupted.  So I think the system is ok now.

 Hi Stephen,

 

Thanks for your quick reaction.

 

I just logged in as root in Tech support mode.

Launched the rnutil chroot command but I got a "killed" message like you can see 

I guess it failed with the message "flush_space+5a" on the  LCD. I still tried the brtf command in case but it failed.

    Here is output of the command, seems a bit better

# rnutil start_raids
mdadm: /dev/md/0 has been started with 4 drives.
mdadm: /dev/md/1 has been started with 4 drives.
mdadm: /dev/md/data-0 has been started with 4 drives.
mount: mounting LABEL=7c6e9e38:data on /data failed: No such file or directory
Scanned Btrfs device /dev/md/data-0

    the mount on /data failed and indeed, it is empty

     

    You can find here https://drive.google.com/open?id=1--vOp-VNXZAUipZuPT-TFqgmk7ltMuwi&usp=drive_fs   the dmesg outpout in case you can find some usefull information.

      Ok.  Does mount | grep md0 show that the OS partition has been mounted?

       

      If not, try mount /dev/md0 /sysroot

       

      If it's mounted, you should then be able to check the usage.

        The /dev/md0 was not mounted.

        I tried to mount it and unfortunatly it failed.

        # mount | grep md0
# mount
rootfs on / type rootfs (rw,size=2011292k,nr_inodes=502823)
proc on /proc type proc (rw,noatime,nodiratime)
sysfs on /sys type sysfs (rw,noatime,nodiratime)
udev on /dev type devtmpfs (rw,noatime,nodiratime,size=10240k,nr_inodes=502828,mode=755)
devpts on /dev/pts type devpts (rw,noatime,nodiratime,mode=600,ptmxmode=000)
# mount /dev/md0 /sysroot
Killed
