PXMX 4.4 Error Backup: -5 input/output error

[Jose A]

Hi Everybody!

Scene: i have proxmox 4.4 with 3 virtual machines (VM's 100,200 and 300), i make backup 300 and 200, all ok, but the backup with the 100 is impossible, i got this error when the backup reaches the 11%.

The space on the machines are similar (50-70 Gb).

I try to make backup to a NAS, the same error, i make backup to a directory, the same error...

I delete the virtual machines 200 and 300 for obtainin more space, but the backup of the 100 it's impossible to make.

With proxmox 3.x the past year i make copy of the machine transfer the file of the virtual machine, but in this new proxmox 4.4 it is not possible, or yes?

Thanks a lot!

Hi,
looks that the hdd-image of vm 100 has an error?!

Which format do you use? (qcow2, lvm, zfs...)?

Hey!
The virtual machine runs good, no problems, the disk is an SSD 240 Gb with 5 months, i plain to change this system to an RAID system with mechanic disks, i use the default system with proxmox 4.4, i think is LVM.

 

[Jose A]

I think the problem can be the free space, but the backup of the other machinews was perfect, i do not understand this.

Hi,
how much free space do you have?

What is the output of following commands?

lvs
df -h

Any info in syslog?

Sorry about this, i'm a rookie in proxmox, i do not view nothing in syslog ( /var/log/syslog )
