do you know how to do this ?
my zpool create :
zpool create -f -o ashift=12 zfs_datastore raidz /dev/sdc /dev/sdd /dev/sde /dev/sdf /dev/sdg special mirror /dev/sda /dev/sdb
I disabled PBS on all nodes. still have writes
seems that writes are caused by txg_sync

Hi,
I finally put this dedicated server on production, and it runs well.
for example, each day at 21:00 I run backup job for all PVE environnements at the same time.
Transfer rate is approaching 500 Mbytes/sec, Cpu utilisation ~50% and bandwidth 2.5-3 Gbps
I'm able to backup ~200 VMs in 30...
Hi
Due to many failed backups and failed verifies, I've decided to delete all the backups and restart from a clean datastore.
But there is still bad chunks :
Do you know how to delete them ?
Thanks
Yes,
Seems that verify does the job on every snapshots even if they are already in status OK.
It could takes hours with hundred (or more) of backups inside !
Hi,
I still have to kill proxmox-backup-client each time Tuxis PBS is unavailable.
For example, today @ 08:00 CET
Nodes are up to date.
Thanks in advance
Thanks,
So the good news is I should able to backup few nodes at the same time considering I have lots of cpus...I guess
