Backup to NFS - when small = ok, large - hangs

[Equand]

Here's the thing, the vmtar command hangs in the backup process:

ll /mnt/vzsnap0
ls: reading directory /mnt/vzsnap0: Input/output error

Is there a way to disable gzipping/tarring the snapshot?
Something like just snapshot directly to the NFS share?

ls: reading directory /mnt/vzsnap0: Input/output error

That usually indicates a problem with your disk.

Is there a way to disable gzipping/tarring the snapshot?

You can disable compression. But tar is our output format, so you can't disable that.

Something like just snapshot directly to the NFS share?

No, that is not implemented.

I see, and our main disk is full, as well as other one. That's what causes the disk problem (otherwise raid hardware would be alarmed).
Ok I will try hacking into it.
Even iscsi target won't help?
