    @stormi I really appreciate the continued help. I'm not sure it works. On my single-host pool master—the one I want to join into my half-upgraded pool—I run the command: xe host-emergency-disable-tls-verification It returns with no errors. If I do xe host-param-list and look through the parameters for my host, I see: tls-verification-enabled ( RO): false This is the only thing I see documented that can turn off TLS verification. If some other command like pool-uninstall-ca-certificate would have the effect of disabling TLS verification, I can't see that documented anywhere. In fact, even though xe pool-uninstall-ca-certificate appears to be a valid command that my xe binary knows about, I can't find that particular command documented at all. Even after the emergency-disable-tls-verification, if I attempt to join that host to the half-upgraded pool (using xe pool-join...) I get: Error code: POOL_JOINING_HOST_TLS_VERIFICATION_MISMATCH It seems like even though the host has TLS verification off, the fact that its pool has verification enabled is blocking the action.

    Hi, Latest XOA, with fully patched XCP 8.3 here. I'm fiddling around again with NBD+CBT in backup jobs (was avoiding CBT for a time, to reliably control my backups and avoid unnecessary KEY points) in the context of THICK SRs to spare some space. I know that CBT is reset when migrating from one SR to another. But here is what I encounter : VM has no CBT enabled on its VDIs, it is on a SHARED SR in a pool of 3 hosts backup option changed for NBD+CBT, was only NBD before CBT is enabled on the next run by the backup job, I get a delta (was expecting a FULL ?) next run, delta, as expected i migrate this VM on another HOST, without changing its SR CBT is immediatly disabled ? why ?? next run of backup it tries a delta, but "fall back to a full" (normal as CBT has been disabled...), and do a KEY point on the remote next run is a delta as expected does this mean if I do a rolling pool update or host maintenance that will move the all VMs around, all CBT will be disabled and I should expect a FALL BACK TO FULL on all my NBD+CBT enabled backup jobs ??! why disabling CBT on a change of HOST and no move of SR ?

    What do you mean "how it works"? It's the same thing than before, just "isolated" from the rest, working in a... worker. And yes, the long run objective is the ability to run it as a service on the remote directly, reducing a lot the merge time (because latency is the worst enemy of merging).

    Backup does not work if one host in the pool is offline

    @olivierlambert said in Backup does not work if one host in the pool is offline: When you connect to a working, machine, yes it does But XAPI connection isn't persistent: it means, when the pool is disconnected, XO has no recollection whatsoever on who was the "real" master the last time it was connected. The only info we store is the IP address you entered in Settings/server. I agree, functionally speaking, it can be limiting in your case. A viable option would be to save all existing hosts IPs in the XO database, as fallback if we can't connect to the IP you entered. This is not a very common case, that's why it wasn't done before Looks like a good suggestion. Thanks. In my case I migrated everything from the poolmaster to the second host, then changed the second host to pool master, waited an hour and then shut down the old pool master (now just a pool member). XOA was online during the entire process and I had forgotten to check the server list.

    That's because the effort to change this will be taken into account in XO 6 Alternatively, you can indeed contribute, this will be very welcome!

    Hi ! We are experiencing these kind of problems because we activated Continous Replication and frequency was way too low. Now I want to eliminate all those files in the chain, can I do it manually from XCP-NG Center or XOA ? Thanks !!! [image: 1635327169557-c2aa1fb3-2ed2-41cf-b242-e2a23e6832e4-image.png]

    It can't be done by XO, because XO is using XAPI to make all calls (there's no XAPI command to rename a file on the SR, also XO isn't connected via SSH, so there's 0 change it was caused by XO). So it was done manually at some point (check your host bash history).

    There's no issue nor restriction to replicate a shutdown VM. CR will work as long as the destination VM never booted (otherwise destination blocks will be modified, so you understand now why we should block boot except if you really know what you do )

    Hi, It doesn't' work that way. XCP-ng is not capable of pushing any data by itself, it has to be pulled. That's exactly why we manage to build XO Proxies to solve this kind of common "enterprise" issue, when you have remote sites

    Backing up the backup

    Doing a bit more hunting it seems like if we could get Arcserve to use the nolock option then that would likely solve the problem, but there's nowhere to add any options and the Arcserve Proxy itself uses the Windows NFS client behind the scenes. Right now we've worked around the problem by creating a separate, read-only SMB share pointing to the same location and using that for Arcserve instead. Our only concern now is what could happen if XO starts a job while Arcserve is still doing its own backup. Edit: I did a bit more Googling after posting the above and came across this thread: https://www.truenas.com/community/threads/nfs-the-process-cannot-access-the-file-because-another-process-has-locked.12644/ ... which suggests that it's actually a long-standing TrueNAS bug. Buried within the comments is this suggestion: If you're having trouble with the NFS locking mechanism, and you would like to use the "NET USE" command, or the [WNetAddConnection] function to mount a NFS share without locking, there's an undocumented registry entry hidden in the NFSNP.DLL: "HKLM\Software\Microsoft\Client for NFS\CurrentVersion\Users\Default\Mount" REG_DWORD "Locking" If the value is "0x0" then locking will be disabled globally. If the value is "0x1" then locking will ben enabled globally. We'll test it and report back.

    @cbaguzman hi, you could try a hard mount instead of soft, then it should constantly retry until it sees the mount again https://www.ibm.com/docs/en/spectrum-protect/8.1.6?topic=considerations-nfs-hard-soft-mounts
