[SOLVED] pve-zsync stuck

[dik23]

pve-zsync seems to have got stuck last night

pve-zsync list
SOURCE                   NAME                     STATE     LAST SYNC           TYPE  CON

101                      101                      ok        2018-09-11_22:31:34 lxc   ssh 
102                      102                      ok        2018-09-11_22:33:55 lxc   ssh 
103                      103                      ok        2018-09-11_22:38:24 lxc   ssh 
104                      104                      ok        2018-09-11_22:30:22 lxc   ssh 
130                      130                      ok        2018-09-11_22:38:04 lxc   ssh

I've tried pve-zsync disable / enable and forcing cron with run-parts /etc/cron.d

I have no problem connecting to the backup destination with ssh

Any ideas?

Did you disable/enable any task before pve-zsync got stuck? If so, it might be related to https://bugzilla.proxmox.com/show_bug.cgi?id=1907

 

[dik23]

That's the one. Thanks. Any news on when a fix will be stable?

No idea, but you can patch your local version in the meantime. See https://pve.proxmox.com/pipermail/pve-devel/2018-September/033689.html for the change.
