    @Bastien-Nollet said in Full backup - new long-retention options: Yes, a backup is kept if it matches one of the retention criteria, either the schedule's retention or the LTR. (the backup is not duplicated, we just check for both criteria to know if we should keep the backup or not) Could we have an option to choose wich LTR day from month to keep ? and even for weekly, what weekday ?

    @LEB-ID It's called Add new Server in XCP-ng Center too... old habits die hard. But Pools is not the right word either. It's hard coming up with something short and precise.

    @olivierlambert said in Backup-NG Error "invalid header checksum" after VM-Disk-Resize and reaching retention Limit.: So the issue appeared just when the oldest extended delta had to be merged in the full I suppose. This is exact, but we need to have a proper process to reproduce it. This might be related to: increasing the size of the disk above a certain threshold increasing the content of the disk above a certain threshold

    After: mount 192.168.10.6:/mnt/raid/nfs /mnt/jan and i look with mount i get this: 192.168.10.6:/mnt/raid/nfs on /mnt/jan type nfs4 (rw,relatime,vers=4.1,rsize=131072,wsize=131072,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=10.211.55.19,local_lock=none,addr=192.168.10.6) So its working. After manual typing what XO tried: mount -t nfs 192.168.10.6:/mnt/raid/nfs/backup /mnt/jan -o vers=3 I get the same error: mount.nfs: access denied by server while mounting 192.168.10.6:/mnt/raid/nfs/backup So the “-o vers=3" option is the problem. Can i edit a file in XO to get rid of the “-o vers=3” option? SOLVED In XO i used the option -o vers=4 and this works.

    @olivierlambert said in Continuous Replication fails with VDI_IO_ERROR(Device I/O errors) on fresh XOA install after XenServer 7.2 -> XCP-ng 8.0 upgrade: To your config file, yes. Where this config file is depends on where do you installed Xen Orchestra (I suppose from the sources, so I can't guess where do you installed, could be anyware ) edit: I think it's fixed now and integrated by default in the config Great, this fix already is in the new version. I was having this problem (Error: VDI_IO_ERROR(Device I/O errors)) and was not be able to do CR of my VMs but now CR works. Thank you PS: BTW that was my config file

    When you click on the link of the error message it should send you to the official documentation, explaining what it means: https://xen-orchestra.com/docs/backup_troubleshooting.html#error-messages I'm not sure to understand the UI question, can you post a screenshot?

    Do you mean to say when you edit the network config box, and fill it out with your own network info (adhering to this standard: https://cloudinit.readthedocs.io/en/latest/topics/network-config-format-v1.html) that cloudinit in the vm gives a yaml error? This indicates the way you filled out the entry box is not properly formatted. Keep in mind to pass networking info, your cloudinit install in your template VM needs to be set to use nocloud data sources, and keep in mind the network configuration passed via cloud-init is added to the template VM, not replaced, so you need to properly configure your template VM to not already have adapters configured with IP addresses etc

    Yes, you are right infact the old instances are halted and are temporarily kept till I am not sure the imported ones are perfectly working on new node. Unfortunately in the meantime I need a way to manage boths and it means xencenter or cli. Thanks for having pointed my attention to the duplicated uiids problem.

    See me previous post here -- https://xen-orchestra.com/forum/post/5072 I'm guessing that you were missing the symlinks for the plugins, otherwise they should have been present in XO.

    I think the simplest way to just do this once is to go to Settings > Config, there you can export the backup. Once you create your new instance of XOCE, you can import the backup using the same page, then just logout of the default user, and you can login using your old credentials. Make sure to delete the admin@admin.net account after.

    So you can't create a backup with XOA Free. This edition is meant for all usual administrative tasks, like XCP-ng Center if you like. If you want backup features, 2 choices: going for XOA Starter, Enterprise or Premium depending on your backup needs. See each edition features here: https://xen-orchestra.com/#!/featuresmatrix (each edition comes with pro support, updater and remote SSH access if needed) install XO from the sources on a system you like, following our guide: https://xen-orchestra.com/docs/from_the_sources.html
