VM doesn't work anymore after umount an lv

i'm not a system administrator so i think that i made a big mistake! we had a problem of storage distribution on VMs in the openstack private cloud. So i took one VM to reduce the storage and i tried first to execute lvreduce to reduce the logical volume but it asks me to umount the lv before. So i run umount <path-of-my-lv> -l and after that i have not access to vms on ssh even when i rebooted it from the openstack dashboard.

I got this Error when i tried to connect using ssh as usual

Remote side unexpectedly closed network connection

any propositioin please ?

Thanks for advance

Solution

  • There is a bad entry on /etc/fstab so the VM doesn't boot anymore.

    By commenting the bad line and restart the machine, it works again and after that you could correct the mounts and lvms.
