Everything was working fine up until like half an error ago than all of a sudden my vm was stuck and i noticed that half of dockers that were running at that time also stopped all of sudden than when i tried launching them back i ended up with execution error code 403 and now when im trying to launch my im getting back this error -- "Hook script execution failed: internal error: Child process (LC_ALL=C PATH=/bin:/sbin:/usr/bin:/usr/sbin HOME=/ /etc/libvirt/hooks/qemu 'Windows 10 New' prepare begin -) unexpected exit status 126: libvirt: error : cannot execute binary /etc/libvirt/hooks/qemu: Input/output error"

im attaching my diagnostics with this post.

please help me figure out how to fix this and how can i prevent it from happening again in the future.

It appears that your cache drive dropped offline (or dropped dead) which is resulting in havoc.  Reseat the cabling to it

if a had not ran that fix common problem plugin, i would have said that that cant be as i was still able to access all my data that was their on my cache drive and under unraid's main page all my drives were active and normal but as i did i know it had something to do with my cache drive as fcp plugin reported two errors and both were about my cache drive.

1. Error --  my cache was read only or completly full

2. error -- unraid was unable to write to docker.img ( we can conclude that this error popped up cause of first error.)

my cache wasn't even half full at that time. so i thought that maybe unraid isn't detecting my cache drive's capacity properly so i rebooted my server and since then its been like 17 hours and 20 minutes and so far everything is working normally, as it should. All my dockers are up and running and my vm's are also working now.

so dont know what really happened.

fortunately one thing is for sure, that my cache didn't dropped dead on me.😅

@Squid hey something similar happened today as well everything was working fine and boom all of sudden my vm is stuck and all my dockers stopped only this time unraid was reporting that their were updates available for all my dockers which is weird but i know that i think this issue happened yesterday at the same time it today and my server is scheduled to auto update all my dockers and plugins at this time.

which lead me to believe that it might has something to do with ca auto update applications plugin.
