Host can't reboot / shutdown

[stephane_c]

Hello,

I have a problem with my proxmox server when I want to reboot or shutdown.
The server shutdown correctly all VMs/containers, but can't shutdown itself (I think I have a kernel panic).

Hardware :

• CPU: Intel(R) Core(TM) i7-7700K CPU
• MB : MSI Product Name: Z270 GAMING PRO (MS-7A59)
• 2x SSD (RAID 1) NVME for system
• 3x HD (RAID 5) for vm/containers

I checked log files, but don't see useful information about this.

Screen when shutdown: ( I can't get more information )

Any way to find more logs / information about this ?

+1 for taking an appropriate screenshot

it looks to me like a disk device was missing at the time of the unmount step of the shutdown
did you unplug a USB key without unmounting properly ?
also does the problem happen on each shutdown ?

Hello,
I don't have usb key, and yes problem happen on each shutdown.

I take an other screen :

in my fstab :
(RPOOL = 2xSSD RAID 1 xfs, md0 => 3xHDD RAID 5)

# <file system> <mount point> <type> <options> <dump> <pass>
/dev/zvol/rpool/swap none swap sw 0 0
proc /proc proc defaults 0 0
/dev/md0        /disks/ ext4    defaults        0       0

root@server:~# zpool list

            nvme1n1p2  ONLINE       0     0     0

errors: No known data errors

Shutdown problem was appeared just after proxmox installation (I was never can reboot server without force hardware)

PVE does not support mdraid. The kernel stack trace indicate that it tried to write out an unmapped buffer. The only references I could find to similar issues are a bug in fallocate/truncate, and interactions with already closed nbd connections. Maybe mdraid has a similar problem?
