Please note that the result from qqa command is not trusted, so you need to
parse
the result if you really want to use it.
Also, sometime guest-fsfreeze-freeze just returns an empty string ''.
Also, it can run into timeouts, and can raise other exceptions.
So please catch exceptions here.

Re: [pve-devel] backup ceph high iops and slow
HI, we talked about this some month ago.. does anybody know if it will be improved soon? So mainly ist a ceph problem. Or also should we communicate with the qemu devs? making bigger backups now takes way to much time. Making a backup from a node wich has about 5tb will take about 36 hours :-( -Ursprüngliche Nachricht- Von: pve-devel [mailto:pve-devel-boun...@pve.proxmox.com] Im Auftrag von Dmitry Petuhov Gesendet: Freitag, 17.

I get around 600 iops for 40mb/sec which is by the way very slow for a backup. When I make a disk clone from local to ceph I get 120mb/sec (which is the network limit from the old proxmox nodes) and only around 100-120 iops which is the normal for a seq read with 120mb/sec... Is the vzdump making problems? It's not vzdump's issue, but qemu's.
