hi team, just flashed Syncloud into a brand new HC4. The boot is ok. I have found only a problem: shutdown -h now does not carry out any effect. On the Rasp Pi4 the same command triggers a real shutdown with a list of services that stop. This is crucial because I don't know the effects on Syncloud system after a "hot" shutdown and, first of all, HC4 contains 2 hard drives and I don't think it's a good idea to switch the system off with disk running. Any comments? Thanks a lot for great support

As I understand shutdown calls systemd so it does a proper stop of all the services.

shutdown -h now does not carry out any effect

That is probably because our uwsgi service does not have a proper shutdown event handler so it waits for 30 seconds before the shutdown (times 2 probably), try waiting for a minute or two.

YES! You are right: proper shutdown and the disks stop. Also with Rasp Pi4 I had to wait for a couple of minutes, the only difference is that with HC4 the console does not give any message, only a blinking cursor while with Rasp the user gets several colorful messages for any service. Anyway, being that I'm gonna perform the shutdown remotely from now on, I'm not interested in what happens console-wise. Thanks a lot.

1. I have followed the guide to use mdadmfor RAID1. Everything flowed smoothly except for the last sudo initramfs-update -u that gave this output: update-initramfs: Generating /boot/initrd.img-4.9.236-63 W: Couldn´t identify type of root file system for fsck hook Could it be an issue for the next boot? UPDATE After a reboot the RAID is still correctly mounted. 2. the RAID 1 is up and running with EXT4 partition (see details below) but Syncloud ask me for formatting it. Note: the size of the RAID is correct. How do I have to go ahead? There is a similar issue for Helios (#433 ) but unfortunately it is not clear what the solution is, if any, because the user has never replied clearly

Here follow the details of the status of RAID1 (md0):

cat /proc/mdstat and df -h -x devtmpfs -x tmpfs :

and sudo mdadm -D /dev/md0 :

and here is lsblk -Jp -o NAME,....:

Thank you very much

First of all this is not correct issue for raid problems (this is much better https://github.com/syncloud/platform/issues/570). Here is the instruction to follow: https://github.com/syncloud/platform/wiki/Multiple-Disks You should unmount the disk first.
