[SOLVED] Can't Open BlockDev(Need Help!)

[lucasprini]

Im getting Can't open blockdev in my dmesg and journalctl in the proxmox HOST.

its tmeta and tdata dms that shows this. Both for my truenasISCSI lvm-thin and the local-lvm thin.

why is this happening, how do i fix? I have normal access to both storages, everything works normally at higher levels, ive already checked the disks health, if its active, if there metadata space, permissions, cant figure out what is going on.
Any insights on this issue?
I'll post my dmesg log in the attachments.

I haven't seen snumbd before, but a quick Google search tells me that is a kernel module developed for the Acronis Cyber Cloud, which is probably used to backup or manage the TrueNAS. Please correct me if I have wrong assumptions here.

It seems like that the snumbd daemon wants access to the LVM thinpool itself (*_tmeta and *_tdata are the metadata and data volumes themselves), which is probably not what you want, except you want to backup the whole thinpool instead of the VM disk volumes itself. I have never used Acronis products however, so I'd suggest to ask the Acronis Support for that matter.

Thanks for your reply, i did have acronis Host Agent installed. Ive reinstalled my proxmox VE cause i had the chance to do so. The problem was solved and i did not need acronis in this host anymore. But thanks for the support, it'll be very useful for future problems.
