Really strange, the snapshots must be exists on both hosts. What say "pve-zsync list" on the host you added the job?
[SOLVED] snapshots ZFS?
- Thread starter killmasta93
- Start date
Thanks for the reply, on host 1 I get this
Code:
root@prometheus:~# pve-zsync list
SOURCE NAME STATE LAST SYNC TYPE CON
123 test2 ok 2018-03-23_21:21:01 qemu sshOk, you have an existing working pve-zsyncjob, you have snapshots on first host, an no Datasets on second host, but an working pve-zsyncjob, sorry for the question, but do you really have the right second host?
Thanks for the reply
not sure what do you mean?
um well in theory the snapshots should be on the host 2 rather then on the host 1? or am i doing this all wrong lol.

On both hosts have to be the same datesets (synct with pve-zsync) and on both hosts have to be the same snapshots. This it how it works. For example here my homesync:
First host (created job)
Secondhost Target:
Code:
@weekly root pve-zsync sync --source v-machines/home --dest [2001:470:1e1b:589:ec4:7bfe:fabb:c725]:v-machines --name home --maxsnap 8 --method sshFirst host (created job)
Code:
zfs list -t snapshot

So the only difference i had from this would be the IP which mine is IPV4, the part of v-machines is that where you also host your vms? on the 2nd host and 1st host?
I think i messed up complete using this guide https://www.servethehome.com/automating-proxmox-backups-with-pve-zsync/
The worst part i cant seem to remove on the 2nd host the vmdata/vmbackup data sheet it keeps saying
so in theory this is what i should do both host 1 and host 2 have the same rpool and vmdata pool
so to backup the vms from host 1 to host 2 it would be like this
Meaning creating from scratch the job backing up vm 123 to host 2 which is going to vmdata?
Thank you
Code:
pve-zsync sync --source v-machines/home --dest [2001:470:1e1b:589:ec4:7bfe:fabb:c725]:v-machines --name home --maxsnap 8 --method sshI think i messed up complete using this guide https://www.servethehome.com/automating-proxmox-backups-with-pve-zsync/
The worst part i cant seem to remove on the 2nd host the vmdata/vmbackup data sheet it keeps saying
Code:
zfs destroy -R vmdata/vmbackup
cannot destroy 'vmdata/vmbackup': dataset already existsso in theory this is what i should do both host 1 and host 2 have the same rpool and vmdata pool

Code:
pve-zsync create --source 123 --dest 192.168.3.80:vmdata --verbose --maxsnap 7 --name test3Thank you
IPV4 and 6, that makes no difference. V-Machines is my Source and on the other machine also the targetpool. No there are no VM's there. The VM's are on an dataset. I sync no VM's, only the datasets from host1, so here HOME.
No, look at the documentation, you need an dataset too.
do i need to have the same data sheet from host 1? as on host 1 i do not have data sheet /vmbackup
No, but it make it much more easier. For example. if i sync VMXXX from host1 to host 2 then i have on host1 and host2 the dateset v-machines/HDD-vmdata-KVM. The advantage is that after moved the configfile to /etc/pve/qemu-server, i'am immediately able to start the VM, without change the config hddpath to special dataset like backup or vmbackup....
Thanks for the reply, but i thought the idea is to have the snapshots on the other host 2 rather then on host 1?
o wow i did not know that howcome? i think that might be the issue as host 1 does not have the same data sheet as host1 might need the vmbackup sheet
I wanted to Thank @fireon that he helped me personally, He found that the issue was that i created a zol running this command
The correct command is
then give it a quota
also the previous vmdata/vmbackup had childs which he helped me to delete which was the reason it wont not delete
Code:
zfs create -s -V 400gThe correct command is
Code:
zfs create vmdata/vmbackup
Code:
zfs set quota=400g vmdata/vmbackupalso the previous vmdata/vmbackup had childs which he helped me to delete which was the reason it wont not delete
would you mind elaborating please? I have used ZFS snapshots before and borg too I am just not sure how to combine those. Please share your solution at least the concept of it.
